Only supported on #8971 Processor (CCIN 26F2)
The Model 570 offers pluggable DIMMs for memory. Each 0/2-way processor
card contains eight slots for up to eight pluggable DIMMs. The minimum memory
for a 9406 Model 570 is 2 GB. The maximum memory capacity depends on the
number of processors ordered for the system and on the type of memory and
functionality required.
The main storage cards are installed according to the following rules. There are
no restrictions for mixing and matching DIMMs other than:
Memory DIMMs must be installed in quads.
Quads must all be the same DIMM.
DIMMs are plugged, by quad, in either of the following sequences:
J0A, J0C, J1A, J1C
J0B, J0D, J1B, J1D
Note: We recommend that you perform memory balancing. You must order
sufficient memory to balance memory across processors.
Memory Spreading and Balancing
Performance measurements have determined that optimal performance requires
both spreading of memory across processors and balancing memory across
processors. The following rules should be followed for Model 570 memory.
