The Dell doc doesn't mention the settings I'm posting about, iops per path, delayed ack, large receive offload. I raised a case with vmware who said they don't make recommendations, they should come from the SAN vendor, and also that they do support changing these settings. I was concerned about that because on this forum someone says vmware told him they don't support iops=1 What's the point of setting IOPS=1? , maybe they didn't when he posted but they do now. I phoned Dell who said they had no recommendations about these settings and I should do my own tests. I've been messing around with them since. We'll decide tomorrow what we think and I'll post it here but we can change it if you or anyone advise otherwise, so I'd still be grateful for opinions.
I wouldn't worry too much about changing them from a support perspective. Only when an issue arises VMware support may ask you to reset it back to 1000.
