Preface As part of an improvement effort, revisions of the software and hardware are periodically released. Some functions that are described in this document are not supported by all versions of the software or hardware currently in use. The product release notes provide the most up-to-date information about product features. Contact your service provider if a product does not function properly or does not function as described in this document.
1 Overview This chapter contains the following information: Topics: • • SMB support Planning considerations SMB support PowerStore T model supports SMB 1 through SMB 3.1.1. When SMB support is enabled on the NAS server, you can create SMB-enabled file systems. The NAS server with SMB support can either be stand-alone or Active Directory domain-joined. Domain-joined NAS servers are placed in the OU=Computers, OU=EMC NAS Servers organizational unit by default.
3. Create a domain account in Active Directory. Creating network VLANs and IP addresses is optional for NAS servers. If you plan to create a VLAN for NAS servers, the VLAN cannot be shared with the PowerStore T model management, or storage networks. Also, be sure to work with your network administrator to reserve the network resources and configure the network on the switch. See the PowerStore Networking Guide for PowerStore T Models for details.
Documentation resources Refer to the following for additional information: Table 2. Documentation resources Document Description Location PowerStore Networking Guide for PowerStore T Models Provides network planning and configuration information. https://www.dell.com/ powerstoredocs PowerStore Configuring NFS Guide Provides information necessary to configure NFS Exports with PowerStore Manager.
2 Create NAS servers This chapter contains the following information: Topics: • • • Overview of configuring NAS servers Create NAS server for SMB (Windows-only) file systems Change NAS server settings Overview of configuring NAS servers Before you can provision file storage on the PowerStore T model appliance, a NAS server must be running on the system. A NAS server is a file server that supports the SMB protocol, NFS protocol, or both to share data with host clients.
Wizard Screen Description Sharing Protocol Select Sharing Protocol Select SMB. NOTE: If you select both SMB and NFS protocols, you automatically enable the NAS server to support multiprotocol. Multiprotocol configuration is not described in this document. Windows Server Settings Select Standalone to create a stand-alone SMB server or Join to the Active Directory Domain to create a domain member SMB server.
NOTE: If you change the Windows Server Type from Standalone to Join to the Active Directory Domain, then you must go to the User Mapping tab and select Enable automatic mapping for unmapped Windows accounts/users. ● Select the FTP card to enable or disable FTP or SFTP, change FTP or SFTP properties, configure user authentication, a user home directory, and authentication message settings. For details see Configure FTP sharing protocol.
3 Additional NAS Server Features This chapter contains the following information: Topics: • • • • Configure FTP or SFTP sharing protocol Configure NAS server networks Enable NDMP backup Configure NAS server Security Configure FTP or SFTP sharing protocol You can configure FTP or FTP over SSH (SFTP) after the NAS server has been created. Prerequisites Passive mode FTP is not supported. About this task FTP access can be authenticated using the same methods as SMB.
Configure file interfaces for a NAS Server You can configure the file interfaces for a NAS server after the server has been added to PowerStore. About this task You can add more file interfaces, and define which is the preferred interface to use. Also, you can define which interface to use for production and backup, or for IPv4, or IPv6. Steps 1. Select Storage > NAS Servers > [nas server]. 2. On the Network page, click Add to add another file interface to the NAS server. 3.
Enable NDMP backup You can configure standard backup for the NAS servers using NDMP. The Network Data Management Protocol (NDMP) provides a standard for backing up file servers on a network. When NDMP is enabled, a third-party Data Management Application (DMA), such as Dell EMC Networker, can detect the PowerStore NDMP using the NAS server IP address. About this task Enabling NDMP is performed after the NAS server is created. PowerStore supports: ● Three-way NDMP.
Understanding Common AntiVirus Agent (CAVA) Common AntiVirus Agent (CAVA) provides an antivirus solution to clients using a NAS server. It uses an industry-standard SMB protocol in a Microsoft Windows Server environment. CAVA uses third-party antivirus software to identify and eliminate known viruses before they infect files on the storage system. Antivirus software is important because the storage system is resistant to the invasion of viruses because of its architecture.
Table 3. Antivirus parameters (continued) Parameter Description Mandatory Example begins, using the configured shutdown parameter (see next row). shutdown= Specifies the shutdown action to take when no server is available. Default value is Allow Access. No Allow Access, Stop_SMB_Access, Disable_Virus_Checker highWaterMark= Alerts the system when the number of requests in progress exceeds highWaterMark.
4 Create file systems and SMB shares This chapter contains the following information: Topics: • • Create a file system Create an SMB share Create a file system A file system must be created on the NAS server before you can create an SMB share. Prerequisites Ensure that there is a NAS server that is configured to support the SMB protocol as described in Configuring NAS servers. Steps 1. Select Storage > File Systems and click Create. 2. Continue to work through the Create File System wizard.
Option Description ● Minimum - Specifies the shortest period for which files can be locked (default value is 1 day). ● Default - Used when a file is locked and no retention period is specified. ● Maximum - Specifies the longest period for which files can be locked. SMB Share Optionally, configure the initial SMB Share. You can add shares to the file system after the initial file system configuration. For details about the SMB Share options, see: Create an SMB share.
Table 4. File system advanced settings for SMB (continued) Setting Description Notify on Write Enabled Enable notification when a file system is written to. This option is disabled by default. Notify on Access Enabled Enable notification when a file system is accessed. This option is disabled by default. Enable SMB Events publishing Enable the processing of SMB events for this file system.
Advanced SMB share properties You can configure the following advanced SMB share properties when you create an SMB share or change its properties: Table 5. Advanced SMB Properties Option Description Continuous Availability Gives host applications transparent, continuous access to a share following a failover of the NAS server on the system (with the NAS server internal state saved or restored during the failover process).
5 More file system features This chapter contains the following information: Topics: • • File-level retention File system quotas File-level retention File-level retention (FLR) enables you to prevent modifications or deletion of locked for a specified retention period. Protecting a file system using FLR enables you to create a permanent, and unalterable set of files and directories.
Configure file-level retention File-level retention is configured at file system creation. For details, see Create a file system. NOTE: Retention period parameters can be modified at a later time. Modify file-level retention About this task Retention period parameters can be set at file system creation or later and can be modified. Modifying retention period parameter does not affect files that are already locked. Steps 1.
Table 6. Quota types (continued) Type Description ● Track directory usage by setting the tree quota hard and soft limits to 0 (zero). NOTE: If you change the limits for a tree quota, the changes take effect immediately without disrupting file system operations. User quota on a quota tree Limits the amount of storage that is consumed by an individual user storing data on the quota tree. Quota Limits Table 7.
Add a user quota onto a file system Create a user quota on a file system to limit or track the amount of storage space that individual users consume on that file system. When you create or modify user quotas, you can use default hard and soft limits that are set at the file-system level. Prerequisites You must enable Quotas and set the User Quota defaults before you can add a User Quota to a files system. See Enable User Quotas. NOTE: You cannot create quotas for read-only file systems. Steps 1.
6 NAS Server replication This chapter contains the following information: Topics: • Overview Overview PowerStore enables you to replicate NAS servers asynchronously between a local system and a remote system. Replication occurs at a NAS server level - all the file systems within the replicated NAS server are replicated to the remote system. RPO is configured at the NAS server level and is identical across all associated file systems.
7 Using CEPA with PowerStore This chapter contains the following information: Topics: • • • • • Events publishing Create a publishing pool Create an event publisher Enabling an event publisher for a NAS server Enable event publisher for a file system Events publishing CEE enables third-party applications to receive event information from the storage system upon accessing file systems.
