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 InfiniBand.
•
One host channel adapter 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.
The network diagram in
Figure 10-1
should be connected for basic testing.

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.
