OneFS Web Administration GuideThe OneFS Web Administration Guide describes how to activate licenses, configure network interfaces, manage the file system, provision block storage, run system jobs, protect data, back up the cluster, set up storage pools, establish quotas, secure access, migrate data, integrate with other applications, and monitor PowerScale clusters.
- About this guideThis guide describes how the PowerScale OneFS web administration interface provides access to cluster configuration, management, and monitoring functionality.
- Scale-out NAS overviewThe scale-out NAS storage platform combines modular hardware with unified software to harness unstructured data. Powered by the OneFS operating system, a cluster delivers a scalable pool of storage with a global namespace.
- Where to go for support This topic contains resources for getting answers to questions about PowerScale products.
- PowerScale scale-out NASPowerScale OneFS combines the three layers of storage architecture—file system, volume manager, and data protection—into a scale-out NAS cluster.
- General cluster administration
- Access zones
- Authentication
- Administrative roles and privileges
- Identity management
- Home directoriesWhen you create a local user, OneFS automatically creates a home directory for the user.
- Data access controlOneFS supports two types of permissions data on files and directories that control who has access: Windows-style access control lists (ACLs) and POSIX mode bits (UNIX permissions).
- File sharingYou can access files and directories using SMB for Windows file sharing, NFS for Unix file sharing, secure shell (SSH), FTP, and HTTP.
- File filteringFile filtering enables you to allow or deny file writes based on file type.
- Auditing
- Snapshots
- Deduplication with SmartDedupe
- Data replication with SyncIQ
- Data layout with FlexProtect
- NDMP backup
  - NDMP backup and recovery overviewIn OneFS, you can back up and recover file-system data through the Network Data Management Protocol (NDMP). From a backup server, you can direct backup and recovery processes between a PowerScale cluster and backup devices such as tape devices, media servers, and virtual tape libraries (VTLs).
  - NDMP two-way backupThe NDMP two-way backup is also known as the local or direct NDMP backup. To perform NDMP two-way backups, you must connect your PowerScale cluster to a Backup Accelerator node which is synonymous with a Fibre Attached Storage node, and attach a tape device to that node. You must then use OneFS to detect the tape device before you can back up to that device.
  - NDMP three-way backupThe NDMP three-way backup is also known as the remote NDMP backup.
  - Support for NDMP sessions on Generation 6 hardwareYou can enable two-way NDMP sessions by configuring them with the optional 2x10GbE + 2x8GB Fibre Channel network interface card (NIC) on Generation 6 nodes. A 2x10GE + 2x8GB Fibre Channel NIC is a hybrid host bus adapter (HBA) that enables two-way NDMP sessions over the Fibre Channel port. Contact Dell EMC Professional Services to enable support for the 2x10GbE + 2x8GB Fibre Channel NIC.
  - Setting preferred IPs for NDMP three-way operations If you are using Avamar as your data management application (DMA) for an NDMP three-way operation in an environment with multiple network interfaces, you can apply a preferred IP setting across a PowerScale cluster or to one or more subnets that are defined in OneFS. A preferred IP setting is a list of prioritized IP addresses to which a data server or tape server connects during an NDMP three-way operation.
  - NDMP multi-stream backup and recoveryYou can use the NDMP multi-stream backup feature, in conjunction with certain data management applications (DMAs), to speed up backups.
  - Snapshot-based incremental backupsYou can implement snapshot-based incremental backups to increase the speed at which these backups are performed.
  - NDMP backup and restore of SmartLink filesYou can perform NDMP backup and restore operations on data that has been archived to the cloud.
  - NDMP protocol supportYou can back up the PowerScale cluster data through version 3 or 4 of the NDMP protocol.
  - Supported DMAsNDMP backups are coordinated by a data management application (DMA) that runs on a backup server.
  - NDMP hardware supportOneFS can back up data to and recover data from tape devices and virtual tape libraries (VTLs).
  - NDMP backup limitationsNDMP backups have the following limitations.
  - NDMP performance recommendationsConsider the following recommendations to optimize OneFS NDMP backups.
  - Excluding files and directories from NDMP backupsYou can exclude files and directories from NDMP backup operations by specifying NDMP environment variables through a data management application (DMA). If you include a file or directory, all other files and directories are automatically excluded from backup operations. If you exclude a file or directory, all files and directories except the excluded one are backed up.
  - Configuring basic NDMP backup settingsYou can configure NDMP backup settings to control how these backups are performed on the PowerScale cluster. You can also configure OneFS to interact with a specific data management application (DMA) for NDMP backups.
  - Managing NDMP user accountsYou can create, delete, and modify the passwords of NDMP user accounts.
  - NDMP environment variables overview NDMP environment variables are associated with paths. When an environment variable path matches with the path of a backup or a recovery operation, the environment variable is applied to that operation.
  - Managing NDMP contextsEach NDMP backup, restore, restartable backup, and multi-stream backup process creates a context. The NDMP server stores the corresponding working files in the context. You can view or delete a context.
  - Managing NDMP sessionsYou can view the status of NDMP sessions or terminate a session that is in progress.
  - Managing NDMP Fibre Channel portsYou can manage the Fibre Channel ports that connect tape and media changer devices to a Fibre Attached Storage node. You can also enable, disable, or modify the settings of an NDMP Fibre Channel port.
  - Managing NDMP preferred IP settingsIf you are performing NDMP three-way operations using Avamar in an environment with multiple network interfaces, you can create, modify, delete, list, and view cluster-wide or subnet-specific NDMP preferred IP settings.
  - Managing NDMP backup devicesAfter you attach a tape or media changer device to a Fibre Attached Storage node, you must configure OneFS to detect and establish a connection to the device. After the connection between the cluster and the backup device is established, you can modify the name that the cluster has assigned to the device, or disconnect the device from the cluster.
  - NDMP dumpdates file overviewWhen you set the UPDATE environment variable to Y, the NDMP daemon maintains a dumpdates file to record all but the token-based backup sessions. The timestamp within the dumpdates file helps identify the changed files for the next level-based backup. The entries within the dumpdates file also provide information about the last backup session at a given path and the type of backup session which can be a full, level-based incremental, or snapshot-based backup. This information determines the type of incremental backup you must run subsequently. The entries within the dumpdates file may be obsolete when the backup path is removed. In such a case, all the obsolete entries can be removed from the dumpdates file.
  - NDMP restore operationsNDMP supports the following types of restore operations:
  - Sharing tape drives between clustersMultiple PowerScale clusters or an PowerScale cluster and a third-party NAS system can be configured to share a single tape drive, which helps to maximize the use of the tape infrastructure in your data center.
  - Managing snapshot based incremental backupsAfter you enable snapshot-based incremental backups, you can view and delete the snapshots created for these backups.
  - Managing cluster performance for NDMP sessionsNDMP Redirector distributes NDMP loads automatically over nodes by using the optional 2x10GbE + 2x8GB Fibre Channel NIC on Generation 6 nodes. You can enable NDMP Redirector to automatically distribute NDMP two-way sessions to nodes with lesser loads. The load-distribution capability results in improved cluster performance when multiple NDMP operations are initiated.
  - Managing CPU usage for NDMP sessionsNDMP Throttler manages the CPU usage during NDMP two-way sessions on 6th Generation nodes. The nodes are then available to adequately support other system activities.
