    What would you give a 2011SBS server in terms of cores and memory with it running as a VM? Im also running the Premium SQL server on 2008R2 STD and also 2008 Web Edition. In the past ive given servers 1-2 cores should i be using more?

    My rule: Start with 1 vCPU, 1GB memory (or more if you're expecting a heavy load, less if you know what you're doing), you can always power off the box and increase both of these at a slide, going down has caused problems in Windows 2003, I hear it's better now though...

    But this practice prevents you from overallocating VMs and never fixing them and having poor consolidation ratios, unused vCPUs means wasted cycles (hypervisor needs to schedule dead CPU time for the VM), overallocation in RAM just means eating more vRAM for OS cache and other waste (for the most part).

    It completely depends on load though, what are you doing, how much of it, etc.
