    Unanswered: New VM sizing recommendation for an existing physical server

    Hi Experts, I am looking for some suggestions on building a new VM sizing recommendation for an existing physical server where SQL server is installed.
    Physical server stats:
    OS: Win 2008 R2
    Processor: Xeon 2.7Ghz..16 cores
    RAM: 64GB

    Can anyone please give the best recommendations for VM sizing (as we are building a new VM replacing this physical server) ..>Thanks much in advance!

    -Sam

    First step would be to get a baseline of the performance of the old server. Is it limited by CPU, Memory, Network? When you have an idea of how the server is running today, you can make a few educated guesses about what resources the server will need in the (near) future.

    A second consideration will be licenses. When moving from one machine to another, you will want to check on your license to see if you have licensed by Core, and are not going to a machine with more cores. This can get costly if Microsoft audits your licenses.

    Thanks for the reply Mcrowley. Well at this point, the server is not much in use and we getting rid of some unused databases as well. So, considering 16 core Intel xeon and 64GB of RAM on current physical server...what would be the best config. to go on new VM? ..Please advise.

    Thank you.
