You first need to enable it using symqos command and then create the cache partition with min and max cache allocated % and then you add your devices to these partition. This will keep you cache intensive devices to remain seperate BUT plan your allocation wisely. You may also want to look at the Analyze option before setting it up to find out action cache usage by your application.

For detailed information, check the Solution Enabler array control CLI guide.
