In case folks are interested in learning more about how this stuff works under the hood, take a look at my related blog posts and read the IISWC academic paper on the topic as well.

Finally, Scott is planning on covering vscsiStats usage in detail during his performance labs at VMworld 2009.

Irfan:

You mentioned at VMworld 2009 that you would like to see vscsiStats included in vCenter. Do you know if this is going to happen? Soon? If not soon, then will there be an ESXi version? My recommendation to roll-out ESX 4.0 vs. ESXi 4.0 would be influenced by the availability of vscsiStats-like data gathering.

Thanks.

Irfan:

I am getting ready to roll out vSphere and still debating ESX vs. ESXi. There is no problem at this time, I just want to be prepared if we encounter performance problems.

aenagy: please get in touch with drummonds (author of this communities doc) if you need access to vscsiStats on ESXi. Stopping deployment of ESXi should not be gated on this issue.

Will do.

Thanks.

Is vscsiStats actually available for ESXi? I was under the impression it was only available on Service Console with the classic ESX

I think you have seen my blog about this already, but I have updated this document to answer your question.
