If lockstep or memory mirroring is used, RDIMMs must be installed in pairs (a minimum of one pair per

each processor), and both RDIMMs in a pair must be identical in type and size. Lockstep and memory

mirroring modes are mutually exclusive. Only one operational memory mode can be enabled on a storage

server, and it is a system-wide setting.
