5.5 HP StorageWorks X9720 Network Storage System Administrator Guide (AW549-96026, March 2011)

• On the client host, run exds_netperf in serial mode against each X9720 Network Storage
System 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:
# exds_netperf --serial --server “16.123.123.1 16.123.123.2”
• On a client host, run exds_netperf in parallel mode, as shown in the following example. In
this example, hosts blue and red are the tested clients (exds_netperf itself could be one of these
hosts or on a third host):
# exds_netperf --parallell \
--server “16.123.123.1,16.123.123.2” \
--clients “red,blue”
Normally, the IP addresses you use are the IP addresses of the host interfaces (eth2, eth3, and so on).
POST error messages

LUN layout
The LUN layout is presented here in case it's needed for troubleshooting.
For a capacity block with 1 TB HDDs:
• 2x 1 GB LUNs—These were used by the X9100 for membership partitions, and remain in the
X9720 for backwards compatibility. Customers may use them as they see fit, but HP does not re-
commend their use for normal data storage, due to performance limitations.
• 1x 100 GB LUN—This is intended for administrative use, such as backups. Bandwidth to these
disks is shared with the 1 GB LUNs above and one of the data LUNs below.
• 8x ~8 TB LUNs—These are intended as the main data storage of the product. Each is supported
by ten disks in a RAID6 configuration; the first LUN shares its disks with the three LUNs described
above.
For capacity blocks with 2 TB HDDs:
• The 1 GB and 100 GB LUNs are the same as above.
• 16x ~8 TB LUNs—These are intended as the main data storage of the product. Each pair of LUNs
is supported by a set of ten disks in a RAID6 configuration; the first pair of LUNs shares its disks
with the three LUNs described above.
X9720 monitoring
The X9720 actively monitors the following components in the system:
• Blade Chassis: Power Supplies, Fans, Networking Modules, SAS Switches, Onboard Administrator
modules.
• Blades: Local hard drives, access to all 9100cc controllers.
• 9100c: Power Supplies, Fans, Hard Drives, 9100cc controllers, and LUN status.
• 9100cx: Power Supplies, Fans, I/O modules, and Hard Drives.
If any of these components fail, an event is generated. Depending on how you have Events configured,
each event will generate an e-mail or SNMP trap. Some components may generate multiple events if
