PS Group Management Storage Manager allows you to centrally manage your PS Groups. For each PS Group, you can configure volumes, snapshots, and replications between a PS Group and Storage Center. You can also configure access policies to grant volume access to hosts. FluidFS Cluster Management Storage Manager allows you to centrally manage your FluidFS clusters and monitor FluidFS cluster status and performance.
Replications and Live Volumes As part of an overall Disaster Recovery Plan, replication copies volume data from one managed storage system to another managed storage system to safeguard data against local or regional data threats. If the source storage system or source site becomes unavailable, you can activate the destination volume to regain access to your data. A Live Volume is a pair of replicating volumes that can be mapped and active at the same time.

Part II Storage Management This section describes how to use Storage Manager to administer, maintain, and monitor Storage Centers and PS Series groups.
3 Storage Center Overview Storage Center is a storage area network (SAN) that provides centralized, block-level storage that can be accessed by Fibre Channel, iSCSI, or Serial Attached SCSI (SAS). How Storage Virtualization Works Storage Center virtualizes storage by grouping disks into pools of storage called Storage Types, which hold small chunks (pages) of data. Block-level storage is allocated for use by defining volumes and mapping them to servers.
Disk Management Storage Center manages both physical disks and the data movement within the virtual disk pool. Disks are organized physically, logically, and virtually. • Physically: Disks are grouped by the enclosure in which they reside, as shown in the Enclosures folder. • Logically: Disks are grouped by class in disk folders. Storage Center enclosures may contain any combination of disk classes. • Virtually: All disk space is allocated into tiers.
Drive Spares Drive spares are drives that Storage Center reserves to replace a drive when one fails. When a drive fails, Storage Center restripes the data across the remaining drives using the spare drive as a replacement for the failed drive. Storage Center designates at least one drive spare for each disk class. For SCv2000 series, SC7020, SC7020F, SC5020, SC5020F, and SCv3000 storage systems, Storage Center groups drives into groups of no more than 21 drives.
Redundancy Redundancy levels provide fault tolerance for a drive failure. • Non-redundant: Uses RAID 0 in all classes, in all tiers. Data is striped but provides no redundancy. If one drive fails, all data is lost. Do not use non-redundant storage for a volume unless the data has been backed up elsewhere. • Single-redundant: Protects against the loss of any one drive. Single-redundant tiers can contain any of the following types of RAID storage.
Table 3. SSD Redundancy Recommendations and Requirements Drive Size Redundancy Level Up to 1.7 TB for WI and RI For most models of Storage Centers, single redundancy is the default when adding drives of this size to a new or existing page pool. NOTE: For drives of this size, dual-redundant the default redundancy level for SCv3000 series, SC7020, SC7020F, SC5020, and SC5020F storage systems. 1.8 TB up to 3.
Emergency Mode Storage Center enters Emergency Mode when the system can no longer operate because it does not have enough free space. In Emergency Mode, Dell Storage Manager Client responds with the following actions: • Generates an Emergency Mode alert. • Expires Snapshots at a faster rate than normal. • Prevents new volume creation. • Volumes are taken offline. Data cannot be written to or read from volumes.
Storage Center Operation Modes Storage Center operates in four modes: Installation, Pre-production, Normal, and Maintenance. Name Description Install Storage Center is in Install mode before completing the setup wizard for the Storage Center. Once setup is complete, Storage Center switches to Pre-Production mode. Pre-Production During Pre-production mode, Storage Center suppresses alerts sent to support so that support is not alerted to expected test scenarios caused by testing.
blocks of data remain on high-performance drives, while less active blocks automatically move to lower-cost, high-capacity SAS drives. Because SSDs are automatically assigned to Storage Tier 1, profiles that include Storage Tier 1 allow volumes to use SSD storage. If you have volumes that contain data that is not accessed frequently, and do not require the performance of Tier 1 SSDs, use a Medium or Low Priority Profile or create and apply a new profile that does not include Storage Tier 1.
If Tier 1 fills to within 95% of capacity, Storage Center creates a space management snapshot and moves it immediately to Tier 2 to free up space on Tier 1. The space management snapshot is moved immediately and does not wait for a scheduled Data Progression. Space management snapshots are marked as Created On Demand and cannot be modified manually or used to create View Volumes. Space management snapshots coalesce into the next scheduled or manual snapshot.
RAID Tiering for SCv2000 Series Controllers RAID Tiering for SCv2000 series controllers moves data between RAID 10 and RAID 5/6. It does not move data between Storage Tiers. RAID Tiering happens at 7 PM everyday. Data progression runs until it completes or reaches the maximum run time. Storage Profiles for SCv2000 Series Controllers The following table summarizes the Storage Profiles available to SCv2000 series controllers.
Summary Tab The Summary tab displays a customizable dashboard that summarizes Storage Center information. The Summary tab is displayed by default when a Storage Center is selected from the Storage navigation tree. Figure 4. Summary Tab Related link Managing Storage Center Settings Viewing Summary Information Storage Tab The Storage tab of the Storage view allows you to view and manage storage on the Storage Center. This tab is made up of two elements: the navigation pane and the right pane. Figure 5.

7 Managing Virtual Volumes With Storage Manager VVols is VMware’s storage management and integration framework, which is designed to deliver a more efficient operational model for attached storage. This framework encapsulates the files that make up a virtual machine (VM) and natively stores them as objects on an array. The VVols architecture enables granular storage capabilities to be advertised by the underlying storage. These storage policies can be created for vSphere Storage Policy-Based Management.
The proper steps for purging data in a LAB environment only are: 1. Using VMware vCenter — Delete all respective VVols VMs 2. Using Storage Center—Perform Purge In the event the order is reversed (by accident), VVols metadata lingers in the database even if Storage Manager is uninstalled. This metadata must be deleted to ensure a robust operating environment if a new lab environment is to be set up and intended to use VVols.
NOTE: Storage containers are not supported outside of the virtual volumes context. You must use Storage Manager to create storage containers. Setting Up VVols Operations on Storage Manager To set up and run operations for virtual volumes (VVols) in Storage Manager, you must: • Register VMware vCenter Server in Storage Manager. • Register VMware vCenter Server in Storage Center either by using Auto manage Storage Center option in Storage Manager or by manually adding vCenter server in Storage Center.
Thick provisioning is not supported for operations such as creating or cloning a VVol VM. Only thin provisioning is supported. VASA Provider The VASA provider enables support for VMware VVols operations. A VASA provider is a software interface between the vSphere vCenter server and vendor storage arrays. Dell provides its own VASA provider that enables vCenter to work with Dell storage. This VASA provider supports the VMware VASA 2.0 API specifications.
5. Click OK. Using Storage Manager Certificates With VASA Provider When you run the Register VASA Provider wizard, the URL of the VASA provider is automatically generated. This URL identifies the host on which the Data Collector is installed. The host is identified as either an IP address or Fully-Qualified Domain Name (FQDN). Depending on how you installed or upgraded Storage Manager or if you changed the host for the Data Collector, you might need to take additional steps to update the certificates.
IP Change Action Required Storage Manager host (or both) to remove FQDN configuration. Restart Storage Manager for the changes to take effect and register VASA Provider again. NOTE: Failure to unregister the VASA Provider before making changes in name lookup service results in initialization errors on vCenter for certain services and causes VASA registration to fail. Managing Storage Containers You can create and use storage containers to organize VMware virtual volumes (VVols) in your environment.
Specifying one or both of these options indicates the data reduction preferences for VMs that are then created. You can also specify options for Data Reduction Input: • None • Compression • Deduplication with Compression These options are presented as checkboxes on the Create Storage Container wizard. NOTE: Even if the Compression Allowed and Deduplication Allowed checkboxes are selected, selecting the None profile option results in no action being taken.
Expected Behaviors for Data Reduction Scenarios The settings specified in both the storage container Data Reduction options and in the VMware Storage Profile determine the results of VM and VVol creation. If the storage container Data Reduction settings conflict with the settings in the VM Storage Profile, creation of VMs and virtual volumes could fail. The following table describes the expected behavior for new VM creation with the Compression option. Table 4.
Table 7. Expected Behavior for Compression and Deduplication Checkboxes on Storage Container Old Checkbox Value New Checkbox Value Expected Behavior Compression Enabled Compression Disabled Data Reduction Profile of existing volumes remains unchanged. Compliance check warns that the VM is not compliant with storage container. Clone/Fast Clone of VM to the same storage container follows rules of Table 4.
Source Datastore Destination Datastore Expected Behavior Storage Container Deduplication = Supported Storage Container Deduplication = Not Supported Default Data Reduction Policy on Container = Deduplication with Compression Destination VM Storage Policy = None Specified Migration succeeds. The volumes on the destination inherit the destination storage container's default Data Reduction Profile.

8 PS Series Storage Array Administration PS Series storage arrays optimize resources by automating performance and network load balancing. Additionally, PS Series storage arrays offer all-inclusive array management software, host software, and free firmware updates. To manage PS Series storage arrays using Dell Storage Manager, the storage arrays must be running PS Series firmware version 7.0 or later. About Groups A PS Series group is a fully functional iSCSI storage area network (SAN).
A group can provide both block and file access to storage data. Access to block-level storage requires direct iSCSI access to PS Series arrays (iSCSI initiator). Access to file storage requires the FS Series NAS appliance using NFS or SMB protocols and the Dell FluidFS scale-out file system. With storage data management features, you can: • Manage a group through several built-in mechanisms such as ssh, serial line, telnet, and web-based user interfaces.

Part III FluidFS v6 Cluster Management This section describes how to use Storage Manager to manage FluidFS clusters running version 6.x. NOTE: FluidFS Cluster Management contains two separate sections, one for FluidFS v6 and one for FluidFS v5 because the GUI procedures are different between these two versions.
13 How FS8x00 Scale-Out NAS Works Dell FS8x00 scale-out NAS leverages the Dell Fluid File System (FluidFS) and Storage Centers to present file storage to Microsoft Windows, UNIX, and Linux clients. The FluidFS cluster supports the Windows, UNIX, and Linux operating systems installed on a dedicated server or installed on virtual systems deploying Hyper-V or VMware virtualization. The Storage Centers present a certain amount of capacity (NAS pool) to the FluidFS cluster.
Term Description Standby controller A NAS controller that is installed with the FluidFS software but is not part of a FluidFS cluster. For example, a new or replacement NAS controller from the Dell factory is considered a standby controller. Backup power supplies Each NAS controller contains a backup power supply that provides backup battery power in the event of a power failure. FluidFS cluster One to six FS8x00 scale-out NAS appliances configured as a FluidFS cluster.
Feature Description Highly available and active-active design Redundant, hot-swappable NAS controllers in each NAS appliance. Both NAS controllers in a NAS appliance process I/O. Multitenancy Multitenancy enables a single physical FluidFS cluster to be connected to several separated environments and manage each environment individually. Automatic load balancing Automatic balancing of client connections across network ports and NAS controllers, as well as back-end I/O across Storage Center volumes.
Overview of the FS8x00 Hardware Scale-out NAS consists of one to six FS8x00 appliances configured as a FluidFS cluster. Each NAS appliance is a rack-mounted 2U chassis that contains two hot-swappable NAS controllers in an active-active configuration. In a NAS appliance, the second NAS controller with which one NAS controller is paired is called the peer controller.
Figure 46. FS8600 Architecture Storage Center The Storage Center provides the FS8600 scale-out NAS storage capacity; the FS8600 cannot be used as a standalone NAS appliance. Storage Centers eliminate the need to have separate storage capacity for block and file storage. In addition, Storage Center features, such as Dynamic Capacity and Data Progression, are automatically applied to NAS volumes. SAN Network The FS8600 shares a back-end infrastructure with the Storage Center.
If client access to the FluidFS cluster is not through a router (in other words, a flat network), define one client VIP per NAS controller. If clients access the FluidFS cluster through a router, define a client VIP for each client interface port per NAS controller. Data Caching and Redundancy New and modified files are first written to the cache, and then cache data is immediately mirrored to the peer NAS controller (mirroring mode).
Scenario System Status Data Integrity Comments Simultaneous dual-NAS controller failure in single NAS appliance cluster Unavailable Lose data in cache Data that has not been written to disk is lost Sequential dual‑NAS controller failure in multiple NAS appliance cluster, same NAS appliance Unavailable Unaffected Sequential failure assumes enough time is available between NAS controller failures to write all data from the cache to disk (Storage Center or nonvolatile internal storage) Simultaneous
14 FluidFS System Management for FS Series Appliances This section contains information about basic FluidFS cluster system management. These tasks are performed using the Dell Storage Manager Client. NAS Access FluidFS v6.x supports the Unicode /UTF-8 encoding, allowing concurrent access from any UTF-8 compatible client. All NAS interfaces expect UTF-8 characters for file, folder/directory, share, and other names. Consequently, all names are internally maintained and managed in UTF-8 format.
Using the Dell Storage Manager Client or CLI to Connect to the FluidFS Cluster As a storage administrator, you can use either the Dell Storage Manager Client or command-line interface (CLI) to connect to and manage the FluidFS cluster. By default, the FluidFS cluster is accessed through the client network. Connect to the FluidFS Cluster Using the Dell Storage Manager Client Log in to the Dell Storage Manager Client to manage the FluidFS cluster.
• From Windows using an SSH client, connect to a client VIP. From the command line, enter the following command at the login as prompt: cli • From a UNIX/Linux system, enter the following command from a prompt: ssh cli@client_vip_or_name 2. Type the FluidFS cluster administrator user name at the login as prompt. The default user name is Administrator. 3. Type the FluidFS cluster administrator password at the user_name’s password prompt. The default password is Stor@ge!.
Service Port FTP (Passive) 44430–44439 SSH 22 Storage Manager communication 35451 Secured management can be enabled only after the system is deployed. To make a subnet secure: • It must exist prior to enabling the secured management feature. • It can reside on the client network (subnet-level isolation of management traffic) or the LOM (Lights Out Management) Ethernet port (physical isolation of management traffic).
Change the Prefix for the Secured Management Subnet Change the prefix for the secured management subnet. 1. the Storage view, select a FluidFS cluster. 2. Click the File System tab. 3.

Enable or Disable Secured Management Enable secured management to exclusively limit management traffic to one specific subnet. Prerequisites • The subnet on which you enable secured management must exist before you enable the secured management feature. • The FluidFS cluster must be managed by Storage Manager using the subnet on which secured management will be enabled.
Rename the FluidFS Cluster Changing the FluidFS cluster name changes the FluidFS cluster name that is displayed in Storage Manager and the name that clients use to access the FluidFS cluster. Prerequisites After changing the FluidFS cluster name, you must also make the following adjustments: • Change the FluidFS cluster name on the DNS server. • If the FluidFS cluster is joined to an Active Directory domain, leave and then rejoin the FluidFS cluster to the Active Directory domain.
View and Configure Time Settings Provide the correct time information for the FluidFS system. An NTP server is mandatory for working with Active Directory.

• Quota rules • Data reduction • Snapshots • NDMP backup • Replication File Security Styles The Windows and UNIX/Linux operating systems use different mechanisms for resource access control. Therefore, you assign each NAS volume a file security style (NTFS, UNIX, or Mixed) that controls the type of access controls (permission and ownership) for the files and directories that clients create in the NAS volume.
– A single NAS volume can contain NFS exports, SMB shares, or a combination of NFS exports and SMB shares. – The minimum size of a NAS volume is 20 MB. (If the volume has already been used, the minimum size should be more than the used space or reserved space, whichever is highest.) • Business requirements – A company or application requirement for separation or for using a single NAS volume must be considered.
Example 3 NAS volumes can be created based on a feature (snapshots, replication, NDMP backup, and so on). • Advantages – The NAS volumes are created to match the exact needs for each feature. • Disadvantage – User mapping is required. A user needs to choose one security style (either NTFS or UNIX) and then, based on the security style chosen, the correct mapping for other users is set.

Refer to the Data Management Application (DMA) documentation for a listing of the variables supported by DMA. If DMA does not set any of the variables, the NDMP server operates with the default value. Table 15. Supported NDMP Environment Variables Variable Name Description Default TYPE Specifies the type of backup/restore application.
Variable Name Description Default During recovery, if this variable is set and if the backup data stream was generated with this variable turned on, the NDMP server handles deleting files and directories that are deleted between incremental backups. Setting this variable requires additional processing time and enlarges the backup data stream size (how much it changes depends on the number of elements in the backup data set). If this feature is not important to the end user, it should not be set.
Figure 49. Two-Way Configuration NOTE: If a controller loses the connectivity to the tape, the NDMP session assigned to the controller will fail. Configuring and Adjusting NDMP Two-Way Backup Tape Connectivity You must define the zoning so that the FC-attached tape drive can be seen by the HBAs on all NAS controllers. Drives must be available through every HBA port so that you can choose which port to use for each backup, and balance the load between HBA ports.
To work around this problem, change the behavior during backup. If a backup is started with the DEREF_HARD_LINK environment variable set to Y, the backup will back up all instances of the hard link files as if they were regular files, rather than just backing up the first instance of the hard link files. In this case, a selective restore will always have the file data. The disadvantage of this option is that backups might take longer and more space is required to back up a data set with hard link files.
Environment Variable Description Used In Default Value TYPE Specifies the type of backup and restore application. The valid values are: Backup and Restore dump • • dump – NDMP server generates inode-based file history tar – NDMP server generates file-based file history FILESYSTEM Specifies the path to be used for the backup. The path must be a directory. Backup None LEVEL Specifies the dump level for the backup operation. The valid values are 0 to 9.
Environment Variable Description Used In Default Value Backup -1 Backup N data set). If this feature is not important in your environment, this variable should not be set. BASE_DATE Specifies whether a token-based backup is performed. Token-based backup is used by Tivoli Storage Manager as an alternative to backups using the LEVEL environment variable. The valid values are: • • DEREF_HARD_LINK -1 – Specifies that token-based backup is disabled 0 – Specifies that a token-based backup is performed.

The following considerations apply when using replication for disaster recovery: • If the original source NAS volume is no longer available, you can configure the recovery NAS volume to replicate to another NAS volume in the original source FluidFS cluster. However, if the original source NAS volume is available, fail back to it. Failing back to the original source NAS volume usually takes less time than failing back to a new NAS volume.
NOTE: If NFS exports are used, the NAS volume names of the source and target should be the same, as the export path name includes the NAS volume name. This is not relevant for SMB shares. ………………………… Source volume An (Cluster A) to target volume Bn (Cluster B) 3.

In the File System tab navigation pane, select Cluster Maintenance. 4. In the right pane, click the Support tab. 5. In the Diagnostic Tools area, click Run Diagnostic. The Run Diagnostic wizard opens. 6. Select the type of diagnostic to run. 7. Select the secondary type (authentication or file access).
NOTE: Power off only the NAS controller on which you are running the embedded system diagnostics. Do not power off the remaining NAS controllers. Powering off a NAS controller disconnects client connections while their clients are being transferred to other NAS controllers. Clients will then automatically reconnect to the FluidFS cluster. 2. Press and release the recessed power button at the back of the NAS controller to turn on the NAS controller. 3.
Steps 1. Connect a network cable to the LOM (Lights Out Management) Ethernet port on a NAS controller. The LOM Ethernet port is located on the lower right side of the back panel of a NAS controller. 2. Connect a Windows client to the iBMC. a. Connect a Windows client to the same network used for the LOM Ethernet port. b. Open a web browser. In the address bar of the web browser, type the iBMC IP address of the NAS controller. The iBMC login page appears. c. In the Username field, type ADMIN. d.
4. The FluidFS cluster and Active Directory server must use a common source of time. Configure NTP and verify the system time is in sync with the domain controller time. Active Directory Configuration Issues Description Unable to add Active Directory users and groups to SMB shares. Cause Probable causes might be: • • • Workaround Unable to ping the domain using a FQDN. DNS might not be configured. NTP might not be configured.
Troubleshooting an NDMP Internal Error Description Backup or restore fails with an internal error. Cause NDMP internal errors are indicators of a file system not being accessible or a NAS volume not being available. Workaround If the backup application cannot connect to a FluidFS cluster: 1. 2. Verify that NDMP is enabled. Verify that the backup application IP address is configured in NDMP. If the backup appliance can connect to a FluidFS cluster, but cannot log in: 1. 2.
Workaround Check the current ACL setting in the Windows client. Redefine the ACLs for the files by using a Windows client the same way you initially defined it. Verify that you set the ACLs as the owner of the files, directories, and SMB shares. If you cannot redefine your ACLs because you currently do not have permissions, perform the following steps: 1. 2. 3. Restore the files from snapshots or a backup.
Workaround This is an informative event. The administrator may contact the locking client and request to close the application referencing this file. It could be that the application that opened the file did not shut down gracefully. It is recommended to reboot the client if possible. SMB Locking Inconsistency Description The SMB service is interrupted due to SMB interlocking issues. Cause There are various SMB client interlocking scenarios.
• • Workaround The FluidFS cluster is restored from a backup or remote replication. During restore time, the directory structure is not complete and a few directories might not exist. When a client with an authorization to access a higher directory in the same path deletes or alters a directory that is being mounted by another client. When multiple clients are accessing the same data set, it is recommended to apply a strict permission level to avoid this scenario. 1.
Workaround If the issue is due to NFS/UDP and firewall, check whether the client mounts using UDP (this is usually the default) and there is a firewall in the path. If a firewall exists, add an appropriate exception to the firewall. If the issue is due to permissions: • • • Verify the path you provided is correct. Check that you are trying to mount as root. Check that the system's IP address, IP range, domain name, or netgroup is in the NFS exports list.
NFS Insecure Access to Secure Export Description A client tries to access a secure export from an insecure port. Cause The secure NFS export requirement means that the accessing clients must use a well-known port (below 1024), which usually means that they must be root (uid=0) on the client. Workaround Identify the relevant NFS export and verify that it is set as secure (requires secure client port).
Workaround • When a client with an authorization to access a higher directory in the same path deletes or alters a directory that is being mounted by another client. When multiple clients are accessing the same data set, it is recommended to apply a strict permission scheme to avoid this scenario. 1. If the FluidFS cluster is being restored, communicate the current status to the client and instruct the client to wait for the restore process to complete.
NFS Access Denied to a File or Directory Description A client cannot access the NFS file or directory despite the fact that the user belongs to the group owning the NFS object and the group members are permitted to perform the operation. Cause NFS servers (versions 2 and 3) use the Remote Procedure Call (RPC) protocol for authentication of NFS clients. Most RPC clients have a limitation, by design, of up to 16 groups passed to the NFS server.
smbclient /// -U user%password -c ls Workaround It is recommended that you use the NFS protocol interfaces to access the FluidFS cluster file system from UNIX/Linux clients. To work around this issue: 1. Ensure that the administrator creates NFS exports to the same locations that you use to access using SMB and connect to them using the mount command from UNIX/Linux clients. 2. Use NFS-based interfaces to access the FluidFS cluster.
Tx_pause for eth(x) on node 1 is off. Cause Flow control is not enabled on the switch(es) connected to a FluidFS cluster controller. Workaround See the switch vendor's documentation to enable flow control on the switch(es). Troubleshoot Replication Issues This section contains probable causes of and solutions to common replication problems.
Replication Target Volume is Busy Reclaiming Space Description Replication between the source NAS volume and the target NAS volume fails because the target NAS volume is busy freeing up space. Cause Replication fails because the target NAS volume is busy freeing up space. Workaround The replication continues automatically when the space is available. Verify that the replication automatically continues after a period of time (an hour).
Replication Source FluidFS Cluster is Busy Description Replication between the source NAS volume and the target NAS volume fails because the file system of the source NAS volume is busy replicating other NAS volumes. Cause Replication fails because the file system of the source NAS volume is busy replicating other NAS volumes. Workaround The replication continues automatically when the file system releases part of the resources.
4. 5. issues and possible authentication problems. In many cases the domain controller is also the NTP server. Verify that the NTP server is up and provides the NTP service. Check the network path between the FluidFS cluster and the NTP server, using ping, for example. Verify that the response time is in the millisecond range. Troubleshooting System Shutdown Description During a system shutdown using Storage Manager, the system does not stop and the NAS controllers do not shut down after 20 minutes.
Controller Taking Long Time to Boot Up After Service Pack Upgrade Description The NAS controller takes a long time to boot up after upgrading the service pack of the NAS controller firmware. Cause The upgrade process can take up to 60 minutes to complete. Workaround • • • 500 Connect a keyboard and monitor to the NAS controller that is taking a long time to boot up. If the system is booting, and is at the boot phase, let the upgrades finish. This can take up to 60 minutes to complete.
Part IV FluidFS v5 Cluster Management This section describes how to use Storage Manager to manage FluidFS clusters running version 5.x. NOTE: FluidFS Cluster Management contains two separate sections, one for FluidFS v6 and one for FluidFS v5 because the GUI procedures are different between these two versions.
23 FS8x00 Scale-Out NAS with FluidFS Overview This section contains an overview of FS8x00 scale-out Network Attached Storage (NAS). How FS8x00 Scale-Out NAS Works Dell FS8x00 scale-out NAS leverages the Dell Fluid File System (FluidFS) and Storage Centers to present file storage to Microsoft Windows, UNIX, and Linux clients. The FluidFS cluster supports the Windows, UNIX, and Linux operating systems installed on a dedicated server or installed on virtual systems deploying Hyper-V or VMware virtualization.
Term Description Controller (NAS controller) The two primary components of a NAS appliance, each of which functions as a separate member in the FluidFS cluster. Peer controller The NAS controller with which a specific NAS controller is paired in a NAS appliance. Standby controller A NAS controller that is installed with the FluidFS software but is not part of a FluidFS cluster. For example, a new or replacement NAS controller from the Dell factory is considered a standby controller.
Feature Description High-performance, scale-out NAS Support for a single namespace spanning up to four NAS appliances (eight NAS controllers). Capacity scaling Ability to scale a single namespace up to 4-PB capacity with two Storage Centers. Connectivity options Offers 1GbE and 10GbE copper and optical options for connectivity to the client network. Highly available and active-active design Redundant, hot-swappable NAS controllers in each NAS appliance.
Overview of the FS8x00 Hardware Scale-out NAS consists of one to four FS8x00 appliances configured as a FluidFS cluster. Each NAS appliance is a rack-mounted 2U chassis that contains two hot-swappable NAS controllers in an active-active configuration. In a NAS appliance, the second NAS controller with which one NAS controller is paired is called the peer controller.
– Internal network – LAN/client network The following figure shows an overview of the scale-out FS8600 architecture. Figure 55. FS8600 Architecture Storage Center The Storage Center provides the FS8600 scale-out NAS storage capacity; the FS8600 cannot be used as a standalone NAS appliance. Storage Centers eliminate the need to have separate storage capacity for block and file storage.
VIPs) on the client network that allow clients to access the FluidFS cluster as a single entity. The client VIP also enables load balancing between NAS controllers, and ensures failover in the event of a NAS controller failure. If client access to the FluidFS cluster is not through a router (in other words, a flat network), define one client VIP per NAS controller. If clients access the FluidFS cluster through a router, define a client VIP for each client interface port per NAS controller.

Each file in the restored NAS volume will have the properties, such as permission and time, that existed when you (or a schedule) created the snapshot.
Managing NDMP The FluidFS cluster supports Network Data Management Protocol (NDMP), which is an open standard protocol that facilitates backup operations for network attached storage, including FluidFS cluster NAS volumes. NDMP should be used for longer-term data protection, such as weekly backups with long retention periods.
Figure 58. Two-Way configuration NOTE: If a controller loses the connectivity to the tape, the NDMP session assigned to the controller will fail. Configuring and Adjusting NDMP Two-Way Backup Tape Connectivity You must define the zoning so that the FC-attached tape drive can be seen by the HBAs on all NAS controllers. Drives must be available through every HBA port so that you can choose which port to use for each backup, and balance the load between HBA ports.
To work around this problem, change the behavior during backup. If a backup is started with the DEREF_HARD_LINK environment variable set to Y, the backup will back up all instances of the hard link files as if they were regular files, rather than just backing up the first instance of the hard link files. In this case, a selective restore will always have the file data. The disadvantage of this option is that backups might take longer and more space is required to back up a data set with hard link files.
Environment Variable Description Used In Default Value TYPE Specifies the type of backup and restore application. The valid values are: Backup and Restore dump • • dump: NDMP server generates inode-based file history tar: NDMP server generates file based file history FILESYSTEM Specifies the path to be used for the backup. The path must be a directory. Backup None LEVEL Specifies the dump level for the backup operation. The valid values are 0 to 9.
Environment Variable Description Used In Default Value Backup -1 Backup N data set). If this feature is not important in your environment, this variable should not be set. BASE_DATE Specifies whether a token-based backup is performed. Token-based backup is used by Tivoli Storage Manager as an alternative to backups using the LEVEL environment variable. The valid values are: • • DEREF_HARD_LINK -1: Specifies that token-based backup is disabled 0: Specifies that a token-based backup is performed.

Replication Scenarios Description Disaster recovery Mirrors data to remote locations for failover during a disaster Configuring replication is a three step process: • Add a replication partnership between two FluidFS clusters. • Add replication for a NAS volume. • Run replication on demand or schedule replication. How Replication Works Replication leverages snapshots. The first time you replicate a NAS volume, the FluidFS cluster copies the entire contents of the NAS volume.
Figure 62.
After a partner relationship is established, replication between the partners can be bidirectional. One system could hold target NAS volumes for the other system as well as source NAS volumes to replicate to that other system. A replication policy can be set up to run according to a set schedule or on demand. Replication management flows through a secure SSH tunnel from system to system over the client network.

• • • Workaround Unable to ping the domain using a FQDN. DNS might not be configured. NTP might not be configured. When configuring the FluidFS cluster to connect to an Active Directory domain: 1. Ensure that you use a FQDN and not the NetBIOS name of the domain or IP address of the domain controller. Ensure that the user has permissions to add systems to the domain. Use the correct password. Configure DNS. The FluidFS cluster and Active Directory server must use a common source of time.
If the backup appliance can connect to a FluidFS cluster, but cannot log in: 1. 2. Use the default user name “backup_user” configured in Storage Manager for the NDMP client while setting up the NDMP backup/restore in your backup application. Use the password configured in Storage Manager for the NDMP client while setting up the NDMP backup/restore in your backup application.
SMB Client Clock Skew Description SMB client clock skew errors. Cause The client clock must be within 5 minutes of the Active Directory clock. Workaround Configure the client to clock-synch with the Active Directory server (as an NTP server) to avoid clock skews errors. SMB Client Disconnect on File Read Description The SMB client is disconnected on file read. Cause Extreme SMB workload during NAS controller failover. Workaround The client needs to reconnect and open the file again.
Workaround The system recovers itself automatically, an event is issued when recovered. SMB Maximum Connections Reached Description The maximum number of SMB connections per NAS controller has been reached. Cause Each NAS appliance is limited to a certain number of connections. Workaround • • • If the system is in an optimal state (all NAS controllers are online) and the number of SMB clients accessing one of the NAS controllers reaches the maximum, consider adding another NAS appliance.
• Manually create the missing directories to enable access. Clients receive errors when trying to access existing data in a deleted path. • Remove the SMB share and communicate this to the client. List all available SMB shares on the FluidFS cluster and identify the problematic SMB share. It must have an indication that it is not accessible. 3. SMB Write to Read Only NAS Volume Description A client tries to modify a file on a read-only NAS volume.
If the FluidFS cluster is not responding due to a port mapper failure: • • • Check the FluidFS cluster status. Check the network connection by trying to NFS mount from some other system. Verify whether other clients experience the same problem. If the FluidFS cluster is not responding due to the program not being registered, check if the port mapper on your client is up.
• If a secure NFS export is not required (for example, the network is not public), ensure that the export is insecure and retry accessing it. NFS Mount Fails Due to Export Options Description This event is issued when an NFS mount fails due to export options. Cause The export list filters client access by IP address, network, or netgroup, and screens the accessing client. Workaround 1. Verify the relevant NFS export details. Write down all existing options so that you are able to revert to them.
• 3. Manually create the missing directories to enable the mount. Clients receive errors when trying to access existing data in a deleted path. • Remove the NFS export and communicate this to the client. List all available NFS exports on the FluidFS cluster and identify the problematic NFS export. It must have an indication that it is not accessible. NFS Owner Restricted Operation Description An NFS client is not permitted to perform the requested action to the specific file.
Workaround A possible way to verify this problem is to use newgrp to temporarily change the primary group of the user and thus ensure it is passed to the server. The simple workaround, although not always feasible, is to remove the user from unnecessary groups, leaving only 16 groups or less. Troubleshoot NAS File Access and Permissions Issues This section contains probable causes of and solutions to common NAS file access and permissions problems.
Strange UID and GID Numbers on Dell NAS System Files Description New files created from Ubuntu 7.x clients get the UID and GID of 4294967294 (nfsnone). Cause By default, Ubuntu 7.x NFS clients do not specify RPC credentials on their NFS calls. As a result, files created from these clients, by any user, are owned by 4294967294 (nfsnone) UID and GID. Workaround To force UNIX credentials on NFS calls, add the sec=sys option to the FluidFS cluster mounts in the Ubuntu fstab file.
Troubleshoot Replication Issues This section contains probable causes of and solutions to common replication problems. Replication Configuration Error Description Replication between the source and target NAS volumes fails because the source and target FluidFS cluster topologies are incompatible. Cause The source and target systems are incompatible for replication purposes. Workaround Verify that both the source and target have the same number of NAS controllers.
Workaround The replication continues automatically when the space is available. Verify that the replication automatically continues after a period of time (an hour). Replication Target Volume is Detached Description Replication between the source NAS volume and the target NAS volume fails because the target NAS volume is detached from the source NAS volume. Cause Replication fails because the target NAS volume was previously detached from the source NAS volume.
Workaround The replication continues automatically when the file system releases part of the resources. Verify that the replication automatically continues after a period of time (an hour). Replication Source is Down Description Replication between the source NAS volume and the target NAS volume fails because the file system of source NAS volume is down. Cause The file system of the source NAS volume is down. Workaround Check whether the FluidFS cluster is down in the source system.
Troubleshooting System Shutdown Description During a system shutdown using Storage Manager, the system does not stop and the NAS controllers do not shut down after 20 minutes. Cause The system shutdown procedure is comprised of two separate processes: • • Stopping the file system Powering down the NAS controllers The file system might take a long time to clean the cache to storage either due to lot of data, or due to an intermittent connection to the storage.
Workaround • • • 662 Connect a keyboard and monitor to the NAS controller that is taking a long time to boot up. If the system is booting, and is at the boot phase, let the upgrades finish. This can take up to 60 minutes to complete. Do not reboot the NAS controller manually if it is in the boot phase.

34 Storage Center Replications and Live Volumes A replication copies volume data from one Storage Center to another Storage Center to safeguard data against local or regional data threats. A Live Volume is a replicating volume that can be mapped and active on a source and destination Storage Center at the same time. Storage Center Replications A Storage Center can replicate volumes to a remote Storage Center and simultaneously be the target of Replication from a remote Storage Center.
Asynchronous Replication Asynchronous replication copies snapshots from the source volume to the destination volume after they are frozen. NOTE: By default, data is replicated from the source volume to the lowest storage tier of the destination volume. To change this default, modify the settings for a replication.
Requirement Description • Asynchronous replication: Version 5.5 or later Storage Center license The source and destination Storage Centers must be licensed for Remote Instant Snapshot. Storage Manager configuration The source and destination storage system must be added to Storage Manager Data Collector. NOTE: Replications cannot be created or managed when the Dell Storage Manager Client is directly connected to a Storage Center.
Topology Limitations for Volumes Associated with Multiple Replications The following limitations apply to volumes that are associated with multiple replications. • Only one synchronous replication can be configured per source volume. Subsequent replications must be asynchronous. • For cascade mode (replications configured in series), only the first replication can be a synchronous replication. Subsequent replications in the series must be asynchronous.

Tiebreaker The tiebreaker is a service running on the Data Collector that prevents the primary and secondary Live Volumes from simultaneously becoming active. If the secondary Storage Center cannot communicate with the primary Storage Center, it consults the tiebreaker to determine if the primary Storage Center is down. If the primary Storage Center is down, the secondary Live Volume activates.
Figure 77. Step Four NOTE: When the primary Storage Center recovers, Storage Center prevents the Live Volume from coming online. Automatic Restore of a Live Volume Enabling Automatic Restore repairs the Live Volume relationship between the primary and secondary Live Volumes after recovering from a failure. After an automatic restore, the original secondary Live Volume remains as the primary Live Volume. The following steps occur during an automatic repair of a Live Volume.
2. The primary Storage Center recognizes that the secondary Live Volume is active as the primary Live Volume. 3. The Live Volume on the secondary Storage Center becomes the primary Live Volume. 4. The Live Volume on the primary Storage Center becomes the secondary Live Volume. Figure 79.

35 Storage Center DR Preparation and Activation Activate disaster recovery to restore access to your data in the event of an unplanned disruption. How Disaster Recovery Works Disaster recovery (DR) is the process activating a replicated destination volume when the source site fails. When the source site comes back online, the source volume can be restored based on the volume at the DR site. The following diagrams illustrate each step in the DR process.
Step 2: The Source Site Goes Down When the source site goes down, the data on the source volume can no longer be accessed directly. However, the data has been replicated to the destination volume. Figure 83. Replication When the Source Site Goes Down 1. Source volume (down) 2. Replication over Fibre Channel or iSCSI (down) 3. Destination volume 4. Server mapping to source volume (down) 5.
Step 4: Connectivity is Restored to the Source Site When the outage at the source site is corrected, Storage Manager Data Collector regains connectivity to the source Storage Center. The replication cannot be restarted at this time because the destination volume contains newer data than the original source volume. Figure 85. Replication After the Source Site Comes Back Online 1. Source volume 2. Replication over Fibre Channel or iSCSI (down) 3. Destination volume (activated) 4.
Step 5B: The Activated DR Volume is Deactivated After the replication from the activated DR volume to the original source volume is synchronized, Storage Manager prompts the administrator to halt IO to the secondary volume. NOTE: IO must be halted before the destination volume is deactivated because the deactivation process unmaps the volume from the server. Figure 87. DR-Activated Volume is Deactivated 1. Source volume being recovered 2. Replication over Fibre Channel or iSCSI 3.
Related link Remote Data Collector Preparing for Disaster Recovery Prepare for DR by saving restore points, predefining DR settings, and testing those settings.
• Up: The replication is up and running normally. • Degraded: There is something wrong with the replication. See to the State column information about why replication is no longer running. This replication is eligible for DR. • 3. Down: The replication is not running. See to the State column information about why replication is no longer running. This could be because the destination system is no longer available or that the source and Destination volume are no longer up and running.
Test Activating Disaster Recovery Testing DR activation for a replication restore point creates a test-activated view volume and maps it to the appropriate server without interrupting service for the original volume. This allows you to make sure that your DR plan is viable. • Periodically test-activate DR for restore points to ensure their the restore point is viable. • DR activation settings specified for test activation are retained for future DR activation and test activation.
Figure 89. Test Activate Disaster Recovery Dialog Box b. Select the server to which the test-activated volume will be mapped by clicking Change next to the Server label. c. Modify the remaining settings for the test-activated volume as needed, then click OK. These attributes are described in the online help. 6.
