Caching can be enabled on the controller, which sets caching on all the RAID array/host drives
configured on the controller. This mode of caching utilizes the memory that is located on the
controller (SDRAM that is either embedded or an inserted DIMM module). The other caching
mode is enabling the caching feature of the hard disk drives. In this method, the cache memory
that is utilized is located on the disk drive and does not use the controller’s memory.
In the event of power loss to the computer system, data located in disk cache is not protected
by the battery backup unit of those controllers that support optional battery backup. The
battery backup only protects data that is located in the controller cache.
