I have an issue with one of my volumes where I have very high disk activity. I can't seem figure out the reasoning. At points the drives just run non-stop when my employees are running programs.
It's a VM server that runs 3 machines - data/programs, printing, and Exchange. The only machine that has this issue is the data-program machine and based on the vmware server console screen it's the data-programs folder which is the one maxing out.
I can not figure out what the problem is. There's very little CPU usage (system process gets up into 20-25% but everything else is pretty low). The disk usage issue seems to correspond with the system process. When the system process is not using CPU then the drives seem to work fine.
It's an older machine (4 years) that had quad Xeon 3.66GHz processors (data-programs has 2 dedicated processors) and 4 GB of RAM which we can't upgrade since the consultants installed server 2003 standard.
Any ideas how I can figure out what's going on?
