Hi,
We are in the process of going to vmware esxi 5 update1. We have built two new hosts, both running AMD opteron 6238 (bulldozer) and 128GB RAM. We have around 20 VMs (mainly windows) running on this platform and bluntly the boxes are struggling! This didnt happen when they were on esx4 on an intel platform with boxes alot less well specced.
Is there anything we can check to ensure everything is in place to prevent sluggish performance?
we have changed a setting in the bios:
active power controller>choose maximum performance
This appears to have made a slight difference, but we dont expect these VMs to perform the way they are with these many resources available!
Thanks.
