About Slow throughput on DXi V1000 NFS Share
We're testing the DXi-V1000 NFS with Vmware Clod backup(ColdClone)
But , throughput is Slow.
throughput ....2~4MB/perSec.
DXi V1000 Disk I/O PS is 100～125. This I/O PS is very Low.
We copy & past big zip file now.but same result.
~~~~VMware HW Spec~~~~~~
ESX 5.1 Server: Hp DL380 2CPU,
V-disk is iscsi Storage.Storage is NEXSAN SATA Disk.
Network is 1Gbps.
NFS share on CentOS is 4000~6000 I/O PS.(File Server)
~~~~~~~~~~~~~~~~~~~~~~
Does anyone know best practice?
Thank you
Atsushi

Hi Atsushi,
A useful tool to rule out some other factors can be the netperf utilitiy. You can use this from the UI Utilities>Analyzer>Network. You can use the v1000 as a netperf server and client both. Try some testing that way and let us know your numbers are from netperf.
Thanks,
Jon

The Diag file can be helpful yes, but the netperf is a direct approach.
