I plan to build a new server for our office to replace existing 6 year old hardware and i am asking for opinion on # of CPU and RAM. We have 55 staff in total and don't expect that # to grow much in next 5 years.
The server will be configured with 3 x VMWARE virtualized Windows Server 2012 Installs as follows:
1. Domain Controller (55 CALs)
2. Exchange 2013 (55 CALs)
3. Remote Desktop (Terminal) Server (20 CALs)
One server guy I know says a single 6 or 8 core Xeon would suffice while another person says go with 2 x 8 core Xeons. I don't want to waste company budget but I'd rather have too much power than not enough.
