7.2.2 Processor operating characteristics
Table 7-1 describes the operating characteristics of the server based on the number of
processors and how the memory is installed. The table also describes how the server will
react in the event of a failure in either processor 1 or 2.

Memory installed Operational characteristics
Processor 1 is installed
Memory installed only on the system
board. Minimum of 2 DIMMs.
Performance improves as DIMMs are added to evenly
populate all ranks on each memory controller.
Memory installed on both the system
board and the mezzanine memory
board.
The memory installed on the mezzanine memory board is
not addressable by processor 1 and is ignored.
Memory installed on both the system
board and the MAX5.
Performance is significantly improved when more active
memory calls are using local memory on the system board.
