When configuring memory mirroring
In addition to the above installation rules, observe the rules below as well when you
configure memory mirroring.
■
Configure a mirroring pair as a unit of eight modules by combining two sets of
memory, with four modules per set. (See Figure 2-5 and Figure 2-6.)
■
For memory groups A and B of each CPU in the SPARC M12-2/M12-2S (16
memory slots), install memory modules that are all of the same capacity and rank.
■
For memory groups A, B, and C of each CPU in the SPARC M12-2/M12-2S (24
memory slots), install memory modules that are all of the same capacity and rank.
■
Set the memory mirror mode for each CPU or CMU.
