Managing FSx for ONTAP volumes

Each storage virtual machine (SVM) on an FSx for ONTAP file system can contain one or more volumes, which are isolated data containers 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 AWS Management Console, AWS 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.

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

  • Volume name

  • Volume type – The type can be RW (the volume is read-writable) or DP (the volume is read-only and can be used as the destination of 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 turn on 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 – You can choose from three built-in policies or use a custom policy that you create in the ONTAP CLI or REST API. For more information, see Snapshot policies.

  • Copy tags to backups – You can enable automatic backups of tags on your volumes using this option in the AWS CLI or Amazon FSx API. For more information, see Copying tags to backups.

You can create up to 500 volumes per file system.
