Expanding the SSD Cache

The SSD cache can be expanded by adding a new SSD RAID group.


Expanding the SSD cache clears all cached data.

  1. Go to Storage & Snapshots > Storage > Cache Acceleration.
  2. Click Manage and then select Expand.

    A confirmation message appears.

  3. Click OK.
  4. Select one or more SSDs.

    All data on the selected disks will be deleted.

  5. Select a RAID type.

    Selecting a RAID type with no disk failure protection (Single, JBOD, RAID 0) when the cache type is Write-only or Read-write may result in data loss.


    RAID 10 provides the best write cache performance.

  6. Click Expand.

    A confirmation message appears.

  7. Click OK.
