Restrictions for each model in using mirroring between processor memory modules
* The same restrictions are applied to the A1080a-S/A1080a-D /A1080a-E/A1040a .
 The memory capacity of each processor memory module that performs mirroring must be the
same.
The following shows the supported memory mirroring configuration.
A1080a-S/A1080a-D/A1040a Model:
Mirroring in the processor memory module : supported
Mirroring between processor memory modules: the following three configurations are
supported.
(1) In the two-processor memory module configuration of processor memory modules #1 and
#2, mirroring of #1 and #2 is performed.
(2) In the three-processor memory module configuration of processor memory modules #1, #2,
and #3, mirroring of #1 and #2 is performed and #3 is not performed.
(3) In the four-processor memory module configuration of processor memory modules #1, #2,
#3, and #4, mirroring of #1 and #2, and #3 and #4 are performed respectively.
#3 #4 #1 #2
#3 #4 #1 #2
#3 #4 #1 #2
NOTE:
Replace the following processor memory modules #1/#2/#3/#4 with
processor memory modules #5/#6/#7/#8 for Server 2 of RA1080a-D
model.
