Creating a Storage Pool

  1. Go to Main Menu > Storage & Snapshots > Storage/Snapshot.
  2. Perform one of the following actions.

    NAS State

    Action

    No volumes or storage pools

    Click New Storage Pool

    One or more volumes or storage pools

    Click Create > New Storage Pool

    The Create Storage Pool Wizard opens.

  3. Click Next.
  4. Optional: If you want to use disks in a connected expansion unit, select the expansion unit from the Enclosure Unit list.

    You cannot select disks from multiple expansion units.

  5. Select one or more disks.
    Warning:

    All data on the selected disks will be deleted.

  6. Select a RAID type.

    Storage & Snapshots displays all RAID types that match the number of selected disks and automatically selects the most optimized RAID type.

    Supported RAID Types

    Default RAID Type

    One

    Single

    Single

    Two

    JBOD, RAID 0, RAID 1

    RAID 1

    Three

    JBOD, RAID 0, RAID 5

    RAID 5

    Four

    JBOD, RAID 0, RAID 5, RAID 6, RAID 10

    RAID 5

    Five

    JBOD, RAID 0, RAID 5, RAID 6

    RAID 6

    Six or more

    JBOD, RAID 0, RAID 5, RAID 6, RAID 10, RAID 50

    Note:

    RAID 10 requires an even number of disks.

    RAID 6

    Tip:

    Use the default RAID type if you are unfamiliar with the technology.

    For details, see RAID Types.

  7. Optional: Select the disk that will be used as a hot spare for this RAID group.

    The designated hot spare automatically replaces any disk in the RAID group that fails.

    For RAID 50 or RAID 60, a spare disk must be configured later. You should configure a global spare disk so that all sub-groups share the same spare disk. For details, see Configuring a Global Hot Spare.

  8. Optional: Select the number of RAID 50 or RAID 60 sub-groups.

    The selected disks are divided evenly into the specified number of RAID 5 or 6 groups.

    • A higher number of sub-groups results in faster RAID rebuilding, increased disk failure tolerance, and better performance if all the disks are SSDs.

    • A lower number of sub-groups results in more storage capacity, and better performance if all the disks are HDDs.

    Warning:

    If a RAID group is divided unevenly, the excess space becomes unavailable. For example, 10 disks divided into 3 sub-groups of 3 disks, 3 disks, and 4 disks will provide only 9 disks of storage capacity.

  9. Click Next.

    The Pool Creation Summary window opens.

  10. Click Create.

    A confirmation message appears.

    Warning:

    All data on the selected disks will be deleted.

  11. Click OK.

QTS creates the storage pool and then displays the information on the Storage/Snapshot screen.
