Today I moved a 350GB Virtual machine from one Datastore to another on a P2000 SAS SAN and was pretty impressed with the performance so I thought I would share. The setup has 24 – 300GB 10k SAS drives, and 12 are in a RAID10 Vdisk, and 11 are in another Vdisk for 2 RAID5 Logical Volumes. I moved the VM from RAID5 to RAID10. It took 9 minutes, and was steady at 375MB/s. It should also be noted that the SAN was also writing new data to the RAID5 as I was also P2V’ing another server.
Here is a screenshot:
I wonder if the new HP P2000 VAAI plugin works with the SAS model?

Think I answered my own question, the HP P2000 Software Plug-in for VMware VAAI White Paper lists the SAS model even though I’m pretty sure the plugin download page indicated that the SAS model was not supported.

Justin – have you tried this?
What use can we gain from using the VAAI plugin?
There are several benefits of using VAAI. Check out the following links for more information: But to put it simply it makes it faster, improves density, and also lets the SAN integrate with VMware better reducing redundant data flow.
