Managing FSx for ONTAP volumes

Each storage virtual machine (SVM) on an FSx for ONTAP file system can have one or more volumes. A volume is an isolated data container for files, directories, or iSCSI logical units of storage (LUNs). Volumes are thin provisioned, meaning that they consume storage capacity only for the data stored in them.

You can access a volume from Linux, Windows, or macOS clients over the Network File System (NFS) protocol, the Server Message Block (SMB) protocol, or over the Internet Small Computer Systems Interface (iSCSI) protocol by creating an iSCSI LUN (shared block storage). FSx for ONTAP also supports multi-protocol access (concurrent NFS and SMB access) to the same volume.

You can create volumes by using the Amazon Web Services Management Console, Amazon CLI, the Amazon FSx API, or NetApp BlueXP. You can also use your file system’s or SVM’s administrative endpoint to create, update, and delete volumes by using the NetApp ONTAP CLI or REST API.

You can create up to 500 volumes per scale-up file system and 1,000 volumes per scale-out file system.

When you create a volume, you define the following properties:

  • Volume style – The volume style can be either FlexVol or FlexGroup. For more information, see Volume styles.

  • Volume name – The name of the volume.

  • Volume type – The volume type can be either Read-Write (RW) or Data protection (DP). DP volumes are read-only and used as the destination in a NetApp SnapMirror or SnapVault relationship.

  • Volume size – This is the maximum amount of data that the volume can store, regardless of the storage tier.

  • Junction path – This is the location in the SVM's namespace where the volume gets mounted.

  • Storage efficiency – You can enable storage efficiency at the volume level. NetApp ONTAP storage efficiency features, including data compaction, compression, and deduplication provide typical storage savings of 65% for general-purpose file sharing workloads.

  • Volume security style (Unix, NTFS, or Mixed) – This setting determines what type of permissions are used for data access on the volume when authorizing users.

  • Data tiering – Set the tiering policy for the volume that defines which data is stored in the cost-effective capacity pool tier. For more information, see Volume data tiering.

  • Snapshot policy – Snapshot policies define how the system creates snapshots for a volume. You can choose from three predefined policies or use a custom policy that you have created using the ONTAP CLI or REST API.

  • Copy tags to backups – Amazon FSx will automatically copy any tags from your volumes to backups using this option. You can set this option using the Amazon CLI or Amazon FSx API. For more information, see Copying tags to backups.
