What I'd like to know is how do I know when its time to upgrade hardware or stop adding virtual servers to a physical box. I am running MS Virtual server 2005. Obviously there are tools such as the simple task manager which show CPU usage... but how can I know when my HDs in a raid setup are being pinged so much and that they are t he bottle neck for the slowness?

You can run perfmon and look at the disk queue length, any more than (2*total disks) i/o  operations queued suggests there may be a bottleneck. diskperf -y plus reboot to turn disk counter on (-n turns off again.) Obviously do this on the host server rather than one of the virtual ones.
