I have a poweredge 2850 that runs fine for 40 mins and then the jet engines take off. I will do this in moderation ever hour. I have heard it is the bios A07 that does this on purpose if you have a raid card in place. I am running VMWARE 4ESXi with 2 3.2Xeon processors 8 gigs of ram. I have 2 server 2000's guests running on the host Any configs for this would be great (ram/processor allocation). The servers themselves are not maxing out ram or cpu at all. The temps on the VM host show normal. The fans rev up to 10 or 11K rpm and then back down to 4500. Any help?
