HP XP7 Owner's Guide

Cache memory
Your HP XP7 can be configured with up to 512 GB of cache memory per controller chassis (1 TB
for a two-module system). Each controller chassis can contain from two to eight cache memory
adapter boards. Each board contains from 8 GB to 64 GB.
Cache memory adaptor boards are installed in pairs and work together to provide cache and
shared memory for the system. Each pair is called a cluster. From one to four cache clusters can
be installed in a controller.

Each drive size requires its own chassis.
Minimum number of drives - Four HDDs or SSDs per controller chassis (two in upper half, two in
lower half). HDDs or SSDs must be added four at a time to create RAID groups, unless they are
spare drives. The minimum number of operating FMD drives is four, one in each FMU in the FBX
chassis. Spares are additional.
