Volume/Performance Information page


Use this page to view a list of the physical and logical attributes of the volume. This information might help in answering performance-related questions. The title of this page depends on whether you are viewing a FlexVol volume or a FlexGroup volume.

Volume attributes

  • Type

    The volume's type; either read-write (RW) or data-protection (DP).

  • Style

    The style of volume; either FlexVol or FlexGroup.

  • Cluster

    The name of the cluster to which this FlexVol volume or FlexGroup volume belongs. You can click the name to display cluster details in the Cluster/Performance Explorer page.

  • Aggregates

    The name of the aggregate on which this FlexVol volume resides, or the number of aggregates on which this FlexGroup volume resides.

    For FlexVol volumes, you can click the name to display aggregate details in the Aggregate/Performance Explorer page. For FlexGroup volumes, you can click the number to display the aggregates that are used in this FlexGroup volume in the Performance/Aggregates Inventory page.

  • Storage VM

    The name of the SVM to which this FlexVol volume or FlexGroup volume belongs. You can click the name to display SVM details in the Storage VM/Performance Explorer page.

  • Tiering Policy

    The tiering policy set on the volume. The policy takes affect only when the volume is deployed on a FabricPool aggregate. The available policies are:

    • None. The data for this volume always remains on the performance tier.

    • Snapshot Only. Only Snapshot data is moved automatically to the cloud tier. All other data remains on the performance tier.

    • Backup. On data protection volumes, all transferred user data starts in the cloud tier, but later client reads can cause hot data to move to the performance tier.

    • Auto. Data on this volume is moved between the performance tier and the cloud tier automatically when ONTAP determines that the data is “hot” or “cold”.

    • All. The data for this volume always remains on the cloud tier.

  • RAID Type

    The redundancy type that is being used on the performance tier of the aggregate where this volume resides. Possible types:

    • RAID0

    • RAID4

    • RAID-DP

    • RAID-TEC


    The value “Not Applicable” is displayed for FlexGroup volumes because the constituent volumes can be on aggregates of different RAID types.

  • Capacity (free/total)

    The total storage available on the volume, in gigabytes, and the amount of storage currently available.

  • Logical Space Used

    The real size of the data that is being stored on this volume without applying the savings from using ONTAP storage efficiency technologies.
