exds_netdiag

The exds_netdiag utility performs tests on and retrieves data from the networking components
in an X9720 Network Storage System. It performs the following functions:
Reports failed Ethernet Interconnects (failed as reported by the HP Blade Chassis Onboard
Administrator)
Reports missing, failed, or degraded site uplinks
Reports missing or failed NICs in server blades

exds_netperf

The exds_netperf tool measures network performance. The tool measures performance between
a client system and the X9720 Network Storage 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– 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 X9720
Network Storage System server blade, as shown in the following example:
exds_netserver -s glory[1-8]
