RAID Array 3000 Controller Shelf The controller supports one (for a single controller) or two (for dual-controllers) standard 72-pin cache SIMMs of up to 64 MB. In a dual-controller setup, both controllers must have identical cache configurations and the total usable cache (per controller) will be half the amount installed due to mirroring. Thus, in a sin- gle controller setup the maximum usable cache is 128 MB while a redundant setup has a maximum usable cache of 64 MB (per controller). The RA
