You are most welcome,
You have to set Delayed ACK and LRO on a per node basis. A reboot is required as well.
Re: DiskTimeOut. Yes, every running VM needs to have this set and in the case of Windows it requires a reboot of the VMs. Check some of your Windows VMs with VMware tools installed the DiskTimeOut value may already be set. It won't set the timeout for Linux, or Solaris, etc.. Just Windows.
Re: Path Redundancy. Any time the array moves or MEM moves a connection to a different port, ESX will generate that message.
Here's a VMware KB about it.
Re: latency errors. When you have gotten into best practices, that I outlined before. DelayedACK, LRO, Multiple Virtual SCSI adatpers in the VMs, those errors will almost certainly stop. Also, make sure you are runnign the most current build of ESXi. Updated kernel and network drivers also tend to resolve those messages, when the other things don't completely eliminate them.
If you haven't done so yet, please download SANHQ from the Equallogic website. This will provide a wealth of info for yourself and tech support when dealing with performance issues.
