DSS on VM hosted on ESX 4.1 Slow Performance

[habibalby]

hello,

I'm using 6.0up50.8401.4786 32bit. I have tried these settings as I have found them in one of the thread in this forum. But nothing helps. Jumbo frames enabled in the ESX vSwitch. I will try the jumbo frame on the DSS site and let you know..

Thanks,

for jumbo frames to work, it must be enable along the entire path.

Hi,
I have enabled it and rebooted the DSS, still same issue. Copy started at 5.5 MB/s and ended up on 1.7 MB/s

Can you test with the latest version and select 64bit mode instead of 32bit?

Hello,
I have tried that, it gives same problem.. Today I'm going to try NFS on windows 2008 32bit and compare the performance.

Any suggestion, please feel free..
Thanks,

On the ESX server where the DSS V6 is installed what is the system RAID settings to be sure that the ESX is tuned for Write cache and other settings.
