Thought I'd ask our resident gurus... I have a brand new HP DL360 server. 8GB memory, 2 quads, 3 SAS drives with a P400i/512 controller w/BBWC.
I am running Windows 2003 R2 Enterpise on the host machine. I also created (4) VMs (each 75GB in size, preallocated) each with a Single vCPU, and 2GB of memory, running Windows 2003 R2 Enterprise. NOTE -- These VMs have NOTHING on them except the O/S. No applications, no nothing. I have serious performance problems as it relates to the VMs becoming unusable for a periond of 15 minutes or so every now and then.... I am noticing, on the HOST, that the logical disk - % write time performance counter just shoots up 100% for as much as 10-15 minutes (see attachment diskusage1.jpg) and then slowly comes down back to near zero (see attachment diskusage2.jpg). The graphs show a total time duration of 16 minutes - FYI... During this high spike of Disk Write % on the host, the VMs themselves are doing NOTHING. Again, they are PLAIN OS installed with nothing installed. Performance monitoring on those VMs shows barely ANY activiate at all, while the host shows 100% disk write %. So it's definitely the host, it seems, causing the poor performance. Also, notice in Attachment diskusage2.jpg the slow decline of Disk Write %... This ALWAYS happens after a period of 100% disk write % usage.... it trails off slowly like that over a 10-15 minute period before it come down to zero again. Any idea what is causing this? I'm thinking about giving up and going to ESXi. ?? picture1 - http://communities.vmware.com/servlet/JiveServlet/download/1260005-23055/dis kusage1.jpg?tstart=0 picture2- http://communities.vmware.com/servlet/JiveServlet/download/1260005-23054/dis kusage2.jpg?tstart=0 Thanks all!
