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 procedures in this section to add or remove SSDs, to configure the MaxIQ cache fetch rate, and to enable MaxIQ caching for a logical device.
To check the status of the SSDs in the MaxIQ pool, including wear-level and longevity indicators, see Maintaining Solid State Drives. To check the MaxIQ cache statistics for a logical device, see Logging Statistics for Remote Analysis.
Note! Before you can enable the MaxIQ cache for a logical device, you must enable read caching.
To configure the MaxIQ cache pool:
In the Logical Devices View, click the Configure MaxIQ Cache Pool button.
The Configure MaxIQ cache pool window opens.
Select one or more SSDs in the Available SSDs list, then click SSD >. (Show Me!)
The SSD is added to the MaxIQ cache pool and the icon changes to indicate that it’s part of the cache.
To remove an SSD from the cache, select one or more SSDs from the MaxIQ Cache Pool list, then click < Cache.
Select the MaxIQ cache fetch rate from the drop-down list: Low, Medium, High. (The default is Medium.)
Click Apply.
The Configure MaxIQ cache pool window closes and the cache configuration is saved.
To enable/disable the MaxIQ cache for a logical device:
In the Logical Devices View, select a logical device.
In the menu bar, select Actions, click Configure MaxIQ, then select Enable MaxIQ Caching or Disable MaxIQ Caching.
