Any volume assigned to use a controller's SSD Cache is not eligible for an automatic load balance transfer.

Currently, only one SSD Cache is supported per storage array.

The maximum usable SSD Cache capacity on a storage array is 5 TB.

SSD Cache is not supported on snapshot images.

SSD Cache is not available on the EF600 or EF300 storage system.

If you import or export volumes that are SSD Cache enabled or disabled, the cached data is not imported or exported.

You cannot remove the last drive in an SSD Cache without first deleting the SSD Cache.

You can enable security on SSD Cache only when you create the SSD Cache. You cannot enable security later as you can on a volume.

If you mix drives that are secure-capable with drives that are not secure-capable in SSD Cache, you cannot enable Drive Security for these drives.

Secure-enabled volumes must have an SSD Cache that is secure enabled.
