of load balancing must be given before the initial system setup and configuration take place. For example, the Intel Pentium Pro processor is optimized for performance using PCI peripherals. The Compaq ProLiant servers that support dual-peer PCI bus architectures provide aggregate I/O throughput - Compaq ProLiant 2500 | PCI Bus Balancing and Optimization on Compaq ProLiant Ser - Page 6
2 explains where to place controllers to enable PCI bus balancing on Compaq ProLiant servers that contain the dual-peer bus architecture. For example, a system configuration might consist of one NIC and two drive array controllers (configuration #3 highlighted in Table 2). As demands change and the - Compaq ProLiant 2500 | PCI Bus Balancing and Optimization on Compaq ProLiant Ser - Page 7
hand, is still available and in a hot-plug slot thus allowing the system administrator time to replace the failed NIC (#4) during non-peak hours, when access to the server is at a minimum. This configuration uses the minimum number of PCI hot-plug slots while providing redundancy to controllers - Compaq ProLiant 2500 | PCI Bus Balancing and Optimization on Compaq ProLiant Ser - Page 8
is optimal and a higher level of availability is achieved. In the third configuration, if the standby network controller failed, no network users would have access to any resources on that server while the system administrator shuts down the system to replace the failed controller.

. The only limitation in this configuration is that one of the active network controllers is located in a non-hot plug slot and therefore cannot be replaced while the system is running.

Before making any modifications, evaluate all of the current network server configurations first. The server configuration might not need to change; therefore, the system administrator might

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.
