Xserve RAID: Controllers appear with different size cache memory in RAID Admin

The two Xserve RAID controllers may have different cache memory sizes when monitored with RAID Admin.
For example, the RAID Admin Components tab reports that one controller module has a Cache Size of 128 MB but the other controller module has a Cache Size of 512 MB.

This can happen after replacing a controller module from an AppleCare Service Parts Kit for Xserve RAID.

This is a valid and fully-supported configuration. It doesn't affect the way Xserve RAID works.
