Performance Balancing
Balancing is the paired arrangement of expansion boards for optimal performance
based on the bus architecture of the expansion slots. When populating boards on a
shared bus, be sure that both boards operate at the same speed (two PCI boards or
two PCI-X boards). To balance expansion board performance, populate slots across
different buses before populating two slots on the same bus. Table 3-15 provides a
recommended expansion slot population order.
Table 3-15: Recommended Expansion Slot Population Order
Slot Number Population Order PCI-X Bus Sharing
1 1
2 4
Shared PCI-X bus
3 2
4 5
Shared PCI-X bus
5 3
6 6
Shared PCI-X bus
Note: This population order is only a recommendation. Expansion boards
can reside in any slot.
