Enable FAST

Cache

FAST Cache is enabled as an array-wide feature in the system properties of the

array in Unisphere

™

. Click the FAST Cache tab, click Create, and then select the

eligible EFDs to create the FAST Cache. There are no user-configurable parameters

for the FAST Cache.

FAST Cache was not enabled for the replica storage in this solution. The replica

images were serviced from the EFDs. Enabling FAST Cache for these LUNs causes

additional overhead without added performance.

If the replica images are stored on SAS disks, enable FAST Cache for those LUNs.

To enable FAST Cache for any LUN in a pool, go to the properties of the pool in

Unisphere™ and click the Advanced tab. Select Enabled to enable FAST Cache,

as shown in the following figure.
