Performance Balancing
Balancing is the paired arrangement of expansion boards for optimal performance
based on the bus architecture of the expansion slots. Properly balancing the boards
across buses can improve performance. To balance expansion boards:
•
Populate slots 1 and 2 with 133-MHz PCI-X boards.
•
Populate slots 3-8 with 100-MHz PCI-X boards.
•
Populate slots across different buses before populating two slots on the same bus.
For more information about PCI-X bus architecture and numbering, refer to the white
paper, PCI Bus Numbering in a Windows NT Environment, on the HP website at:
