Hi Rahul, First of all thanks a lot for the detailed mail. It will help me a lot. But what I am concerned about right now, is to find out the actual utilization of each physical server. This is how I can determine how many applications I can club into what kind of machines. Some applications are home made and some are like SAP and Oracle DBs. I am planning to calculate the utilization of each server over a week and month's time. Also want to calculate the peak load it gets and when does it get that. I am looking at resources such as CPU, Physical M/m, swap space, NIC and FC Card utilizations. Please add whatever else comes to your mind that I should consider too.

So, I won't be much worried about that.

Thanks again for the quick response. You guys rock!!
