Introduction to the DR Series System Documentation 1 The DR Series system documentation contains topics that explain how to use the Dell DR Series system to perform data storage operations and manage storage and replication containers. The topics in this administrator’s guide introduce and describe the DR Series system graphical user interface (GUI), which you use to manage your backup and replication operations.
• • • • Dell DR Series System Command Line Reference Guide — provides information about managing DR Series system data backup and replication operations using the DR Series system command line interface (CLI). Dell DR Series System Getting Started Guide — provides an overview of setting up your DR Series system hardware and includes technical specifications.
Understanding the DR Series System 2 The Dell DR Series system is a high-performance, disk-based backup and recovery appliance that is simple to deploy and manage and offers unsurpassed Total Cost of Ownership benefits. Features such as innovative firmware and an allinclusive licensing model ensure optimal functionality and provide the assurance of no hidden costs for valuable future features.
About the DR Series System The Dell DR Series system is a backup and recovery solution designed to reduce your backup data footprint by using a number of comprehensive backup and deduplication operations that optimize storage savings. The DR Series system is available in the following models: • DR2000v—a Virtual Machine (VM) template for ESX and Hyper-V. • DR4000—which consists of pre-installed DR Series system software on a Dell PowerEdge R510 appliance platform.
enclosures. Adding an expansion shelf provides additional data storage for the DR Series system and also requires a license. Each added expansion shelf enclosure must be equal to or greater than each DR Series system internal drive slot capacity (0–11). For more information, see the topic, “Expansion Unit Limits,” in the Dell DR Series System Interoperability Guide and the related Expansion Shelf topics in this guide.
The DR Series system supports the 64:1 replication of data (32:1 if on the DR4X00 and 8:1 for the DR2000v), whereby up to 64 source DR Series systems can write data to different individual containers on a single, target DR Series system. This supports, for example, the use case where branch or regional offices can each write their own data to a separate, distinct container on a main corporate DR Series system.
Replication Replication is the process by which key data is saved from storage locations, with the goal of maintaining consistency between redundant resources in data storage environments. Data replication improves the level of fault-tolerance, which improves the reliability of maintaining saved data and permits accessibility to the same stored data. The DR Series system uses an active form of replication that lets you configure a primary-backup scheme.
Replication Seeding The DR Series systems support replication seeding, which provides the ability to create a local seed and place it in a remote system. The seed backup is a process on the source DR Series system, which collects all of the unique data chunks from the containers and stores them on the target device. This is helpful if you have a new replication target DR to set up, the amount of data to be replicated is very large, and the network bandwidth is low.
Under this scenario, a fraction of the data to be recovered is sent across the WAN link. This could speed up a remote restore significantly. However, there are some downsides to this type of scenario: • If step 1 is not followed correctly, any changes not fully replicated are lost. • During steps 2 and 3, any data that is written to the original DR Series system source container may be lost. • During step 4, if the data is not fully replicated back before the switch is made, it may be lost.
NFS is a client-server application in which a client can view, store, and update files on a remote system just like they are working on a local system. System or Network Administrators can mount all or a portion of a file system, and the file system (or portion) that is mounted can be accessed using the privileges assigned to each file. NOTE: If you want to do a mount on AIX, you must set the nfs_use_reserved_ports and portcheck parameters first. The parameters cannot be set to 0.
NOTE: Any user that is part of BUILTIN\Administrators can edit ACLs on CIFS shares. The local DR Series system administrator is included in the BUILTIN\Administrators group. To add additional domain groups to the BUILTIN \Administrators group, you can use the Computer Manager tool on a Windows client to connect to the DR Series system as Domain administrator and add any groups you want. This capability allows users other than the Domain administrator to modify an ACL as needed. • • • • • • • BUILTIN\
• Group (group in which the owner belongs) • Other (other users with an account on the system) Each of these three user types support the following access permissions: • Read (read access that allows user to read files) • Write (write access that allows user to create or write to a file) • Execute (access that allows user to execute files or traverse directories in the filesystem) NOTE: A root user has all levels of permission access, and a user can be a member of a single group or of multiple grou
such as CommVault, EMC Networker, and Tivoli Storage Manager. For the current list of qualified DMAs, see the Dell DR Series System Interoperability Guide. Rapid NFS is a new client file system type that ensures that only unique data is written to the DR Series system. It uses user space components and file system in user space (FUSE) to accomplish this. Metadata operations such as file creates and permission changes go through the standard NFS protocol, whereas write operations go through RDNFS.
– • • • Provides throughput that is significantly better than CIFS or NFS RDA with OST and DMA integration: – OpenStorage API enables the DMA-to-media server software communications – DR Series system storage capabilities can be used without extensive changes to DMAs – Backup and replication operations are simplified by using built-in DMA policies DR Series system and RDA with OST: – Control channel uses TCP port 10011 – Data channel uses TCP port 11000 – Optimized write operations enable cli
– Restore – Replication Supported Virtual Tape Library Access Protocols The DR Series system supports the following virtual tape library (VTL) tape access protocols. • Network Data Management Protocol (NDMP) • Internet Small Computer System Interface (iSCSI) NDMP The Network Data Management protocol (NDMP) is used to control data backup and recovery between primary and secondary storage in a network environment. For example, a NAS server (Filer) can talk to a tape drive for the purposes of a backup.
external expansion shelf enclosures (see the DR Series Expansion Shelf section in this topic). The hot-swappable data drives that are attached to the RAID controller are configured as: • 11 drives that operate as RAID 6, which act as virtual-disks for data storage (drives 1–11). • The remaining drive (drive 0) acts as the global hot-spare drive for RAID 6 for the system for the DR4000, DR4100 and DR6000 and a dedicated hot spare for the DR4300e, DR4300, and DR6300.
NOTE: If you are running a DR Series system with an installed release of system software prior to 2.1, and you intend to upgrade to release 3.x system software and add an external expansion shelf (or shelves), Dell recommends that you observe the following best practice sequence of operations to avoid any issues: • Upgrade the DR Series system with the release 3.

NOTE: For the DR4300e, DR4300, and DR6300, the MD1400 expansion shelf enclosure is used for data storage expansion. The MD1400 has 4 ports in each controller or EMM; and, Dell recommends using ports 1 and 2 on the MD1400. If you plan on installing multiple expansion shelf enclosures, then the two SAS In ports on the rear chassis of the EMM on the additional enclosure are daisy-chained to the two SAS Out ports on the EMM rear chassis on the first enclosure.
Figure 5. SAS Port and Cable Connections (Dell PowerVault MD1200 EMM) 1. SAS cable 2. pull-tab Adding a DR Series Hardware System Expansion Shelf To set up, add, and connect an expansion shelf correctly to a DR Series hardware system appliance, you need to complete the following tasks. • Power off the DR Series system. • Install all cabling that connects the external expansion shelf (or shelves) to the DR Series system (For information, see the topic, DR Series System — Expansion Shelf Cabling).
5. Once the previous step completes, to verify that an enclosure was added, click Dashboard→ Health. The Health page is displayed, and each properly cabled and activated expansion shelf enclosure has a corresponding tab that displays a green status check mark (for example, if you have installed two enclosures, two tabs are displayed: Enclosure 1 and Enclosure 2).
Setting Up the DR Series System Hardware 3 You can interact with the DR Series system hardware using one of two supported methods: a web-based graphical user interface (GUI) accessed using a web browser or a command line interface (CLI) using a terminal emulator application (for example, PuTTY). Before you can interact with your system, you must first, however, ensure that the DR Series system is properly set up. NOTE: The topics in this section apply to physical DR Series systems.
• IP Addresses: You need to make sure to have IP addresses that you use for the DR Series system. The DR Series system ships with a default IP address and subnet mask address, which should only be used for an initial system configuration. NOTE: You need to have an IP address available to replace the default IP address if you choose the static mode of IP addressing, or select to use the DHCP mode of IP addressing.
Initializing the DR Series System Before you can start using the DR Series system graphical user interface (GUI) for the first time, you must properly initialize the system. To initialize the DR Series system, complete the following: 1. Log in to the DR Series system CLI by using a local console KVM (keyboard-video monitor) connection or an iDRAC connection. For more information, see Local Console Connection, or iDRAC Connection. 2.
If your network does not accept the default subnet mask address (255.0.0.0), you can establish a connection between the DR Series system and a laptop workstation. In this case, make sure that you connect using SSH, and use the default IP address to run the Initial System Configuration Wizard. If you are using a known static IP address, you can skip running the Initial System Configuration Wizard, and directly configure the DR Series system using its user interface.

For more information, see Modifying the System Password.
3. To log in using the default password, type St0r@ge! , and click Login. NOTE: After you have reset the login password to its default and logged in to the DR Series system, Dell recommends for security reasons that you create a new unique login password. 4. In Service Tag, type the Service Tag associated with your system.
The System has successfully rebooted dialog is displayed after rebooting (system reboot may take up to 10 minutes to complete). Configuring Active Directory Settings You need to configure the Active Directory setting to direct your DR Series system to join or leave a domain that contains a Microsoft Active Directory Service (ADS). To join an ADS domain, complete steps 1 through 4 in the following procedure (to leave an ADS domain, skip to step 5).
Configuring Local Workgroup Users Settings You need to configure settings to create a local workgroup of CIFS authenticated users. This capability lets you create a local workgroup (Local Workgroup Users) to which you can add new users, edit existing users, or delete users from the workgroup. To configure the DR Series system for a Local Workgroup Users, complete the following: 1. Select System Configuration → Local Workgroup Users. The Local Workgroup Users (CIFS) page is displayed. 2.
3. In Email Address, type a valid email address using the address format that your email system supports. 4. Click Submit to configure the recipient email address (or click Cancel to display the Email Alerts page). The Email Alerts page is displayed, and an Added email recipient dialog is displayed when successful. 5. To create additional recipient email addresses, repeat steps 2 through 4.

The Email Relay Host page is displayed, and an Updated external email server information dialog is displayed when successful. Configuring System Date and Time Settings If you need to configure or manage the date and time settings used by your system that synchronize it with other DR Series systems or clients running in your domain, navigate to the Date and Time page, and click Edit.
NOTE: If the DR Series system is joined to a Microsoft Active Directory Services (ADS) domain, the Edit option will be disabled (grayed out) and the Mode, Time Zone, or Date and Time values cannot be changed in the Settings pane. This is because whenever a DR Series system is joined to a domain, the Network Time Protocol (NTP) is disabled and the DR Series system uses the domain-based time service. NTP is used in the Mode setting when the DR Series system is part of a workgroup and not joined to a domain.
This administrative tool lets you control access to shares and also configure read-only or read-write access to user groups or individual users within the Active Directory Service (ADS) when joined to an ADS domain. To implement share-level security on a DR Series system that has been joined to an ADS domain, make sure that you have mapped a drive on the DR Series system using an account with DOMAIN\Administrator credentials (or by using an account that is equivalent to a domain administrator).
Managing DR Series Storage Operations 5 This chapter describes how to use the DR Series system to perform data storage operations, including creating and managing containers, setting up and managing replication, viewing detailed client information, and setting up and managing encryption. Understanding the Storage Page and Options To open the Storage page, click Dashboard → Storage.
Understanding the Storage Options The DR Series system stores backed up and deduplicated data that has been ingested by the system into easily accessible storage containers. A number of system storage operations are available in the DR Series system graphical user interface (GUI) that simplify the process for storing this type of data.
NOTE: Use Select to identify the container on which you want to perform an action. For example, click Select, and click Display Statistics to display the Container Statistics page for the container you selected. Replication Page To display the Replication page, click Storage → Replication. The Replication page displays the number of source replications, the names of the local and remote containers, the peer state, and the bandwidth selected per container.
• Plug-In — The plug-in type installed on each client. • Backup Software — The backup software used with each client. • Idle Time — The idle time (non-activity) for each client. • Connection — The number of connections for each client. • Mode — The current mode type for each client. Clients Page (Using the NFS or CIFS Tabs) On the Clients page (Storage→ Clients), click the NFS or CIFS tab to view the following information for NFS or CIFS clients.
If an OST or RDS client is set to run in Auto mode, the OST or RDS client will run in the mode setting determined by the media server. • The following table shows the relationship between the configured OST or RDS client mode types and the supported client mode based on client architecture type and corresponding number of CPU cores. For information about Rapid NFS and Rapid CIFS supported client modes based on architecture and CPU cores, see Best Practices: Rapid NFS and Best Practices: Rapid CIFS.
Managing Container Operations This topic describes using the DR Series system to manage your data storage and container operations. Data storage operations include tasks such as creating new containers, managing or deleting existing containers, moving data into containers, and displaying current container statistics. Creating Storage Containers By default, the DR Series system provides a container named backup for your use after you complete the basic system configuration and initialization process.
6. For Marker Type, select the appropriate marker that supports your DMA. • None — Disables marker detection for the container. • Auto — Automatically detects CommVault, Tivoli Storage Manager (TSM), ARCserve, and HP Data Protector marker types. In addition, select this option if you need to support EMC Networker 2.0. • Networker — Supports EMC Networker 3.0. If you need to support EMC Networker 2.0, select Auto. • Unix Dump — Supports the Amanda marker, among others.
access clients list box. (To delete an existing client from this list box, select the IP address (or FQDN hostname) of the client you want to delete, and click Remove. The “deleted” client disappears from the list box.) NOTE: The DR Series system administrator that manages the system has a different set of privileges than does the CIFS administrator user. Only the DR Series system administrator can change the password for the CIFS administrator user.

Additional tapes can be added as required. For more information, see the topic, VTL and DR Series Specifications. 8. 9. For Access Protocol, select one of the following options. • NDMP • iSCSI • No Access (select this option if you are not ready to select a protocol.
For iSCSI, you should configure the CHAP password for the system-wide CHAP account. To do so, you can use the CLI or navigate to Storage > Clients, and then click Edit CHAP Password. You can add additional tapes to the library after container creation by editing the container in the GUI or by using the following CLI command: vtl --update_carts –-name --add --no_of_tapes NOTE: For more information about using the command line interface, see the Dell DR Series Command Line Reference Guide.
3. Modify the marker type for the selected container as needed. For details, see the topic, Creating Storage Containers. CAUTION: If you are changing the marker type on a DR6000 and you are using Rapid CIFS, you must remount the share on the client after you change the marker type. 4. Modify the connection type options for the selected container as needed.

Refer to the Dell DR Series System Interoperability Guide for details about the supported system limits for replication per DR Series system model. For a definition of connections and streams, see Streams_vs_Connections. • Version Checking — The DR Series system software includes version checking that limits replication only between other DR Series systems that run the same system software release version.
CAUTION: Exercise care when configuring the direction of replication for source and target containers. For example, target containers can have their contents deleted if they contain existing data. NOTE: Because you cannot modify an existing defined role (source or target replica) for a replication relationship, if necessary, you must delete the existing replication relationship, and then recreate a new relationship with the specific source and target roles that you want. 1. Select Storage→ Replication.
4. To start the scheduled replication process, click Start, and click OK to start replication (or click Cancel to display the Replication page). The Successfully started replication dialog is displayed. Adding a Cascaded Replica To add a cascaded replica to an existing replication relationship, complete the following steps. 1.

Using Global View 7 This topic describes how to monitor and navigate to multiple DR systems in your enterprise using the Global View feature, which provides a real-time view of multiple DR systems in your enterprise. About Global Views The Global View is a dashboard that provides a holistic picture of all DR Series systems added to it, making it easy to monitor and manage remote systems. For example, suppose you are an administrator in a headquarters office with a DR Series system.
• All DR Series systems must be in the same Active Directory Services (ADS) domain, in the same login group, and have identical login credentials. This includes the system to which you are currently logged in. For details, see the procedures that follow. • When you use Global View, you must log in to the DR Series system using your domain credentials; for example, you must log in as DOMAIN\Administrator instead of Administrator.
Adding a Login Group in an ADS Domain After you configure your DR systems within the same ADS domain, you must ensure that a login group exists and add it to the domain. Adding a login group is only possible when the DR Series system is already joined to a domain. Also, you must be logged in as a domain user that is part of an enabled login group. To add a login group in an ADS domain, complete the following: 1. Select System Configuration → Active Directory. The Active Directory page is displayed.
Global View Summary NOTE: If an alert is displayed with a message that "Member units will fail to connect because non-Active Directory credentials were used", see Prerequisites.

9 Configuring and Using Rapid NFS and Rapid CIFS Rapid NFS and Rapid CIFS enable write operation acceleration on clients that use NFS and CIFS file system protocols. Similar to OST and RDS, these accelerators allow for better coordination and integration between DR Series system backup, restore, and optimized duplication operations with Data Management Applications (DMAs) such as CommVault, EMC Networker, and Tivoli Storage Manager.
The Rapid NFS plugin (driver) must be installed on client systems After the plug-in is installed, write operations will go through Rapid NFS while metadata operations such as file creates and permission changes will go through the standard NFS protocol. Rapid NFS can be disabled by uninstalling the plug-in. Markers must be set on the client, not in the DR Series GUI If you are using a DMA that supports a marker, should explicitly set it.
Best Practices: Rapid CIFS This topic introduces some recommended best practices for using Rapid CIFS operations with the DR Series system. Containers must be of RDA containers cannot use Rapid CIFS. If you have existing NFS/CIFS containers, you do not type NFS/CIFS need to create new containers to use Rapid CIFS; you can install the plug-in (driver) to existing clients.
Installing the Rapid NFS Plug-In The Dell Rapid NFS plug-in must be installed on to the media server type you choose (for supported operating systems and DMAs, see the Dell DR Series System Interoperability Guide). The plug-in software enables integration between DR Series system data storage operations and the supported data management applications (DMAs). Before you install, make sure you adhere to the Best Practices covered in another topic in this chapter.
NOTE: If you want to do a mount on AIX, you must set the nfs_use_reserved_ports and portcheck parameters first. The parameters cannot be set to 0. For example: root@aixhost1 / # nfso -po portcheck=1 root@aixhost1 / # nfso -po nfs_use_reserved_ports=1 To ensure that the plug-in is running successfully, check the log file at: tail -f /var/log/oca/rdnfs.log.

Configuring and Using VTL 12 This topic introduces Virtual Tape Libraries (VTLs) and related concepts and tasks. Refer to the subsequent topics and procedures in this section for more information. Understanding VTL A Virtual Tape Library (VTL) is an emulation of a physical tape library on a disk-based deduplication and compression system such as the DR Series system.
NDMP The Network Data Management protocol (NDMP) is used to control data backup and recovery between primary and secondary storage in a network environment. For example, a NAS server (Filer) can talk to a tape drive for the purposes of a backup. You can use the protocol with a centralized data management application (DMA) to back up data on file servers running on different platforms to tape drives or tape libraries located elsewhere within the network.
NOTE: For more information about using the CLI, see the Dell DR Series CLI Reference Guide. A library can only contain tapes of the same size. For example, if the library is originally created with 10 tapes of size 10GiB, additional tapes of size 10GiB can only be added.
Refer to the topics, Creating Storage Containers and Creating a VTL Type Container, for detailed instructions about creating containers. Refer to the Dell DR Series System Command Line Interface Guide for details about the CLI commands for creating containers. Authentication/User Management Considerations • You can use the following commands to view user information and manage passwords for the iSCSI user: iscsi_user, and NDMP user: ndmp_user.
Configuring and Using Encryption at Rest 13 This chapter introduces the concept of Encryption at Rest as used by the DR Series system as well as related concepts and tasks. NOTE: Due to export regulations, the encryption at rest feature is not available in certain markets, and, therefore, may not be available in your locale. Refer to the subsequent topics for more information. Understanding Encryption at Rest Data that resides in the DR Series system can be encrypted.
Term Description Internal mode A mode of key lifecycle management in which the keys are periodically generated and rotated. The minimum key rotation period before the content encryption key can be rotated and a new key is generated is 7 days. This rotation period is user-configurable and can be specified in days. Encryption at Rest and DR Series Considerations This topic describes key features and considerations of using Encryption at Rest in the DR Series system.
The administrator must set a passphrase as the first step in configuring encryption. This passphrase is used to encrypt the content encryption keys, which adds a second layer of security to the key management. 2. Enabling encryption and setting the mode. The administrator should enable encryption by using the GUI or CLI. At this time, the mode is also set. The default key management mode is “internal” mode, in which key rotation happens periodically as specified by the set key rotation period. 3.
