Best CPU and memory Allocation

[nimaghajarieh]

Hi,

I am going to migrate my physical server (DC, File, exchange on one physical server!!) to a new DellPE T420 with 1 socket CPU and 6 cpu cores * 2,199 GHz + 32GB RAM. I have installed ESXI 5.5 on this new server and can have 2 VMs whith server 2012 standard.

First of all, i want to now how to devide these services between 2 VMs. I thought to have DC,AD and files on one VMS and exchange on anouther one.

anouther question is what is the best allocation for these two VMs(CPU and Memory)

Welcome to the Community - Ideally you will want to match what the physical machines resource consumption - so if the source server is only using 2-4 GB of RAM you will only want to assign the 4 GB at most - wit CPU if the utilization is low say less than 10% I would only assign a wingle vcpu

Match to the physical specs of the box if you can. Storage is easily, you know exactly how much you use today so size accordingly +20/30%, with thin provisioning there's no reason to make it even larger.

As far as CPU/Memory goes keep in mind you can always resize and up the limits on the fly.. thats the beauty of virtualization.
