Configuring the MaxIQ Cache The MaxIQ cache is a global read cache pool. It uses the Solid State Drives (SSDs) in your system as fast cache memory for read-intensive operations. You can configure the MaxIQ cache only if you have one or more MaxIQ-compatible Solid State Drives installed on the RAID controllers in your system. Note: For MaxIQ caching applications, you can use any Solid State Drive on the compatibility list, including Adaptec MaxIQ SSDs and, with some controllers, select SSDs from other manufacturers. See www.adaptec.com/compatibility for a list of MaxIQ-compatible Solid State Drives. Adaptec Storage Manager assigns all compatible SSDs to the MaxIQ cache pool, by default. Use the following procedures to add or remove SSDs, to configure the MaxIQ cache fetch rate, and to enable MaxIQ caching for a logical drive. To check the status of the SSDs in the MaxIQ pool, including wear-level and longevity indicators, see Working with Solid State Drives on page 90. To check the MaxIQ cache statistics for a logical drive, see Viewing Statistics on page 123. Note: Before you can enable MaxIQ caching for a logical drive, you must enable read caching; see page 64.

Adaptec Storage Manager assigns all compatible SSDs to the MaxIQ cache pool, by default. Use
the following procedures to add or remove SSDs, to configure the MaxIQ cache fetch rate, and
to enable MaxIQ caching for a logical drive.
To check the status of the SSDs in the MaxIQ pool, including wear-level and longevity
indicators, see
