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
  - Snapshots overviewA OneFS snapshot is a logical pointer to data that is stored on a cluster at a specific point in time.
  - Data protection with SnapshotIQYou can create snapshots to protect data with the SnapShotIQ software module. Snapshots protect data against accidental deletion and modification by enabling you to restore deleted and modified files. To use SnapshotIQ, you must activate a SnapshotIQ license on the cluster.
  - Snapshot disk-space usageThe amount of disk space that a snapshot consumes depends on both the amount of data stored by the snapshot and the amount of data the snapshot references from other snapshots.
  - Snapshot schedulesYou can automatically generate snapshots according to a snapshot schedule.
  - Snapshot aliasesA snapshot alias is a logical pointer to a snapshot. If you specify an alias for a snapshot schedule, the alias will always point to the most recent snapshot generated by that schedule. Assigning a snapshot alias allows you to quickly identify and access the most recent snapshot generated according to a snapshot schedule.
  - File and directory restorationYou can restore the files and directories that are referenced by a snapshot alias. You can copy the data from the snapshot, clone a file from the snapshot, or revert the entire snapshot.
  - Best practices for creating snapshotsConsider the following snapshot best practices when working with a large number of snapshots.
  - Best practices for creating snapshot schedulesSnapshot schedule configurations can be categorized by how they delete snapshots: ordered deletions and unordered deletions.
  - File clonesSnapshotIQ enables you to create file clones that share blocks with existing files in order to save space on the cluster. A file clone usually consumes less space and takes less time to create than a file copy. Although you can clone files from snapshots, clones are primarily used internally by OneFS.
  - Snapshot locksA snapshot lock prevents a snapshot from being deleted. If a snapshot has one or more locks applied to it, the snapshot cannot be deleted and is referred to as a locked snapshot. If the duration period of a locked snapshot expires, OneFS will not delete the snapshot until all locks on the snapshot have been deleted.
  - Snapshot reserveThe snapshot reserve enables you to set aside a minimum percentage of the cluster storage capacity specifically for snapshots. If specified, all other OneFS operations are unable to access the percentage of cluster capacity that is reserved for snapshots.
  - SnapshotIQ license functionalityYou can create snapshots only if you activate a SnapshotIQ license on a cluster. However, you can view snapshots and snapshot locks that are created for internal use by OneFS without activating a SnapshotIQ license.
  - Creating snapshots with SnapshotIQTo create snapshots, you must configure the SnapshotIQ licence on the cluster. You can create snapshots either by creating a snapshot schedule or manually generating an individual snapshot.
  - Managing snapshotsYou can delete and view snapshots. You can also modify the name, duration period, and snapshot alias of an existing snapshot. However, you cannot modify the data contained in a snapshot; the data contained in a snapshot is read-only.
  - Restoring snapshot dataYou can restore snapshot data through various methods. You can revert a snapshot or access snapshot data through the snapshots directory.
  - Managing snapshot schedulesYou can modify, delete, and view snapshot schedules.
  - Managing snapshot aliasesYou can configure snapshot schedules to assign a snapshot alias to the most recent snapshot created by a snapshot schedule. You can also manually assign snapshot aliases to specific snapshots or the live version of the file system.
  - Managing with snapshot locksYou can delete, create, and modify the expiration date of snapshot locks.
  - Configure SnapshotIQ settingsYou can configure SnapshotIQ settings that determine how snapshots can be created and the methods that users can access snapshot data.
  - Set the snapshot reserveYou can specify a minimum percentage of cluster-storage capacity that you want to reserve for snapshots.
  - Managing changelistsYou can create and view changelists that describe the differences between two snapshots. You can create a changelist for any two snapshots that have a common root directory.
