From the console whats your output for the following

esxcfg-vswitch -l
esxcfg-vmknic -l
esxcfg-nics -l
esxcli swiscsi nic list -d vmhba32

Thanks for you help AdStar

If i do esxcli swiscsi nic list -d vmhba32 i get this:

~ # esxcli swiscsi nic list -d vmhba32
Could not find valid OIDs for adapter vmhba32
Errors:

But if i do esxcli swiscsi nic list -d vmhba34 i get this:

~ # esxcli swiscsi nic list -d vmhba34

an update:
i have setup raid 0 for speed test but i still have the same performance, I do not know which is the bottleneck in my setup.

thanks

Another update:

The previous tests were made with the target configured in File I/O mode with WB enabled.
I ran test with WB disable, also in the controller WB was disabled but the performance was too slow.

Recently i have configured the DSS V6 Lite with Block I/O with WB enabled. Now i have a better performance but it still slow.

Esxi says that the nics are transmitting about 30.000 Kbps each.

What other test I can do to figure out what is the problem?

Thanks!

try upgrading to latest V6 b5087, and switch to SCST1.0

[m.casco]

Gr-R:


I´m already using DSS V6: 6.0up55.8101.5087 64bit and SCST1.0.

The strange thing is that i can move a 41 Gb archive from the esxi to the DSS V6 in less than 10 minutes but, in a VM, IOmeter shows 25 Mb maximun.

I don´t know if is the processor (athlonII x2 245, 2.9 ghz) is my bottleneck:



Thanks!!!
