66 low latency aspects of the fabric, a minimum of dual Xeon servers (in the neighborhood of 2.0 GHz) with 133Mhz PCI-X expansion busses are required. • An Ethernet switch should be used to network the two servers together. This switch can be of any speed, but a gigabit version will provide the best platform for comparing high performance communication over Ethernet and IB. • One HCA is required for each server. • A utility called netperf is also required for performance testing. The tool and more information can be found by going to http://www.netperf.org, or by contacting your sales engineer for a pre-built RPM. Install the netperf server and client on both servers in the test setup. Network Topology The network diagram in Figure 10-1 illustrates the way two servers, a switch, and an Ethernet network should be connected for basic testing. Test Client Host (Listener) Figure 10-1: Sample Test Topology Host and Switch Setup For basic inter-fabric testing of the switch, no configuration is required on the switch itself; therefore, configuration of the switch's management interface can be left for later. • For instructions on installing the HCAs, please refer to "Installing the Host Channel Adapter" on page 5. This section will instruct you how to physically install the HCAs into your servers. • To install the ULP drivers, please read and follow the instructions in "Installing HCA Host Drivers" on page 12. NOTE: Do not continue on to configure the drivers after the installation, as this will be described below to suit the appropriate environment.
