we have 2 of 5 S7000FCUR Systems with 2 X7350 Processors witch causes very high CPU load when more than 1 VM ist loaded. With 3 VMs the ESX nearly freezes. The system was running with ESX 3 without problems since june 2008.
What we did in the past:
Updated Firmware and RAID controller to latestet Versions
Made an PCT without Errors
Changed the CPUs from an System without errors
Installed ESX 4 min. 3 times
Does anybody have an idea ?
Thanks in advance
Doesn't sound familiar. Do the ESX logs report any errors?
may be try to reinstall the Vmtools in Virtual machines.
Need more info to resolve the issue.
