PCI Bus Balancing and Optimization on
Compaq ProLiant Servers
With the introduction of dual-peer PCI (Peripheral Component Interconnect) bus
architecture, Compaq recommends balancing the load between the two PCI buses to
achieve optimal performance on the server.
This white paper identifies the importance of PCI Bus Balancing and provides technical
configurations for achieving high performance and availability on bridged PCI buses
and dual-peer PCI bus architectures.
