A colleague of mine the other day asked me how much memory (RAM) and disk space does the Hyper-V role take up when it’s installed on Windows Server 2012 R2. It was a good question as I didn’t know, and there seems to be no information out on TechNet sites or blog sites about it.
So, I thought I’d find out for myself and post up the results. I used the full GUI version of Windows Server 2012 R2 – the first screen shot is memory usage and free disk space of a brand new, fresh build of Server 2012 R2. The only thing I’ve done to the server is join it to the domain.
You can see I’m using 496mb of RAM and I’ve used 8.6Gb of disk space to install the operating system.
I then installed the Hyper-V role and all the GUI management tools by using the following Powershell commands.
Enable-WindowsOptionalFeature –Online -FeatureName Microsoft-Hyper-V –All -NoRestart
Install-WindowsFeature RSAT-Hyper-V-Tools -IncludeAllSubFeature
After a reboot, this is how much memory and disk space the Hyper-V role used up.
And there you have it. It looks like the Hyper-V role uses approximately 61mb of memory and 900mb of disk space.
