exds_netperf
The exds_netperf tool measures network performance. The tool measures performance between
a client system and the HP ExDS9100 system. Run this test when the system is first installed. Where
networks are working correctly, the performance results should match the expected link rate of the
network, that is, for a 1 GB link, expect about 90 MB/s. You can also run the test at other times to
determine if degradation has occurred.
The exds_netperf utility measures streaming performance in two modes:
• Serial—Streaming I/O is done to each network interface in turn. The host where exds_netperf
is run is the client that is being tested.
• Parallel—Streaming I/O is done on all network interfaces at the same time. This test uses several
clients.
The serial test measures point-to-point performance. The parallel test measures more components of
the network infrastructure and could uncover problems not visible with the serial test. Keep in mind
that overall throughput of the parallel test is probably limited by client’s network interface.
The test is run as follows:
• Copy the contents of /opt/hp/mxso/diags/netperf-2.1.p13 to an x86_64 client host.
• Copy the test scripts to one client from which you will be running the test. The scripts required are
exds_netperf, diags_lib.bash, and nodes_lib.bash from the /opt/hp/mxso/diags/
bin directory.
• Run exds_netserver -s <server_list> to start a receiver for the test on each HP ExDS9100
server blade, as shown in the following example:
exds_netserver -s glory[1-8]
• Read the README.txt file to build for instructions on building exds_netperf and build and
install exds_netperf. Install on every client you plan to use for the test.
• On the client host, run exds_netperf in serial mode against each HP ExDS9100 server in turn.
For example, if there are two servers whose eth2 addresses are 16.123.123.1 and 16.123.123.2,
use the following command:
