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
- File retention with SmartLock
- Protection domains
- Data-at-rest encryption
- S3 Support
- SmartQuotas
- Storage pools
  - Storage pools overviewOneFS organizes different node types into separate node pools. You can configure node pool membership to include node types that you specify, and you can add node types to, and remove node types from, existing node pools. You can organize these node pools into logical tiers of storage. By activating a SmartPools license, you can create file pool policies that store files in these tiers automatically, based on criteria that you specify.
  - Storage pool functionsWhen a cluster is installed, and whenever nodes are added to the cluster, OneFS automatically groups nodes into node pools. Autoprovisioning of nodes into node pools enables OneFS to optimize performance, reliability, and data protection on the cluster.
  - AutoprovisioningWhen you add a node to a cluster, OneFS attempts to assign the node to a node pool. This process is known as autoprovisioning, which helps OneFS to provide optimal performance, load balancing, and file system integrity across a cluster.
  - Node poolsA node pool is a group of three or more nodes that forms a single pool of storage. As you add nodes to the cluster, OneFS attempts to automatically provision the new nodes into node pools.
  - Virtual hot spareVirtual hot spare (VHS) settings enable you to reserve disk space to rebuild the data in the event that a drive fails.
  - SpilloverWhen you activate a SmartPools license, you can designate a node pool or tier to receive spillover data when the hardware specified by a file pool policy is full or otherwise not writable.
  - Suggested protectionBased on the configuration of your PowerScale cluster, OneFS automatically calculates the amount of protection that is recommended to maintain Dell EMC PowerScale stringent data protection requirements.
  - Protection policiesOneFS provides a number of protection policies to choose from when protecting a file or specifying a file pool policy.
  - SSD strategiesOneFS clusters can contain nodes that include solid-state drives (SSD). OneFS autoprovisions nodes with SSDs into one or more node pools. The SSD strategy defined in the default file pool policy determines how SSDs are used within the cluster, and can be set to increase performance across a wide range of workflows. SSD strategies apply only to SSD storage.
  - Other SSD mirror settingsOneFS creates multiple mirrors for file system structures and, by default, stores one mirror for each of these structures on SSD. You can specify that all mirrors for these file system structures be stored on SSD.
  - Global namespace accelerationGlobal namespace acceleration (GNA) enables data on node pools without SSDs to have additional metadata mirrors on SSDs elsewhere in the cluster. Metadata mirrors on SSDs can improve file system performance by accelerating metadata read operations.
  - L3 cache overviewYou can configure nodes with solid-state drives (SSDs) to increase cache memory and speed up file system performance across larger working file sets.
  - TiersA tier is a user-defined collection of node pools that you can specify as a storage pool for files. A node pool can belong to only one tier.
  - File pool policiesFile pool policies define sets of files—file pools—and where and how they are stored on your cluster. You can configure multiple file pool policies with filtering rules that identify specific file pools and the requested protection and I/O optimization settings for these file pools. Creating custom file pool policies requires an active SmartPools license.
  - Managing node pools in the web administration interfaceYou can manage node pools through the OneFS web administration interface. You must have the SmartPools or higher administrative privilege.
  - Managing L3 cache from the web administration interfaceYou can manage L3 cache globally or on specific node pools from the web administration interface. You must have the SmartPools or higher administrative privilege. On HD400 nodes, L3 cache is turned on by default and cannot be turned off.
  - Managing tiersYou can move node pools into tiers to optimize file and storage management. Managing tiers requires the SmartPools or higher administrative privilege.
  - Creating file pool policiesYou can configure file pool policies to identify logical groups of files called file pools, and you can specify storage operations for these files.
  - Managing file pool policiesYou can modify, reorder, copy, and remove custom file pool policies. Although you can modify the default file pool policy, you cannot reorder or remove it.
  - Monitoring storage poolsYou can access information on storage pool health and usage.
