I have some applications running on servers.

I have want to downsize the servers which are underutilized

what factors should I consider.

1) how to reduce RAM lets say from 8gb to 4gb save some ram (any tools recommended) how to find if RAM is not fully utilized.
2) CPU- things to be considered- like quad core or dual core, clock speed ( what else do one consider in cpu if it is not utilized and tools recommended to check )

This isn't making much sense as worded.  Ideally, you should be virtualizing your servers so that they take up fewer physical servers and utilize resources more thoroughly.

You should be checking your resource utilization using AT LEAST Task Manager and probably setting up a log in Performance Monitor to see what kinds of loads you have.

No, sorry.  I don't use ESXi.  I prefer Hyper-V.  And the best thing to do with that is learn it by setting up a test system and playing - ask questions on aspects you don't know or understand.

You can do a search on EE for something like "virtual servers" or "visualization" or "Hyper-V" and then look on the right side of the screen and select the article box and then go down and select some of the other criteria to better search what you would like to find. There are a lot but I agree with suggestion above to setup and play around with a virtual server and then ask questions as you encounter problems. There are also a ton of videos on youtube that can help you.

Hello

If you use a phisical server removing RAM or CPU don't have much sense. (The RAM can be used on other servers if compatible only, the CPU is more difficult), so the way is to virtualise your server, then you can play with the amount of RAM and Processor.
 you can use a converter http://www.vmware.com/fr/products/converter, beter than reinstalling your server on a virtual platform.
On ESX platform you can see the real CPU/RAM consomation for each virtual server and for all servers, like graph just by using Vsphere client, on Microsoft HyperV you will use Hyper-V Resource Metering.
All has advantages, you just need to chose one.
