Memory Installation Configuration Rules
You can mount up to 4 memory boards on the SPARC Enterprise M4000 server and
up to 8 memory boards on the SPARC Enterprise M5000 server. The DIMMs on the
memory board are grouped into group A and group B. (See
).
Here are the DIMM mount conditions:
■
In each group, 4 DIMMs are mounted in a unit.
■
The size of the DIMMs in group A must be equal to or larger than the size of the
DIMMs in group B. You need not necessarily mount DIMMs in group B.
■
In each of the groups, mount the DIMM of same size and of same rank. The
DIMMs of different size cannot be mixed in a group.
■
To replace with the DIMMs of different size or different rank, you need to follow
the above conditions on every memory board in the same CMU.
Note –
When you upgrade using larger size memory than the size of Group A, move
the memory mounted in Group A to Group B, and then mount the upgrade memory
to Group A.
