Figure 25: Cache module DIMM locations

Note: The cache size requirement for running ACS V8.8-

P or V8.8-

S is 512 MB.

For ACS V8.8-

F, V8.8-

G, and V8.8-

L, the minimum cache size requirement is

128 MB in unmirrored configurations and 256 MB in mirrored configurations, per

cache module. Failure to upgrade cache memory appropriately can result in an

inoperable controller and increase subsystem down-time.
