Can you run a x64 OS VM under VMware vSphere on an HP Microserver?

I was recently asked by a TechHead reader whether the HP Microserver’s AMD Athlon II Neo based CPU, the N36L (on older models) or the N40L (on newer models), has AMD-V capabilities and can support x64 operating systems, for example Microsoft Windows Server 2008 R2.  This definitely warranted a quick post just to help clarify things, as this may be a question that HP Microservercrossed the minds of a few of you. 

Well, the good news is that both the AMD Athlon II Neo N36L & N40L processors have the AMD-V virtualization instructions on the CPU and are capable of running x64 operating system based VMs under VMware vSphere.  And to prove this, here is a couple of screen shots from one of my HP Microservers (N36L) running VMware ESXi 5 with a Windows Server 2008 R2 (x64) VM.

Will an x64 OS run on an HP Microserver running vSphere 5

Hope this helps answer this question, and as always feel free to drop me a line with any such questions.  Thanks to Adam McAndrew for the original question that inspired this post.

    I’m very tempted by the idea of one of these machines to replace my home server (and to file server at the office, but that is another matter).

    I’m pretty sure that the CPU will be up to what I run on the existing machine (stock Debian with Samba for file sharing, Apache for simple web sites, and a very small Zimbra install in a VM (currently vbox)), but I’m not sure about the drives and have a couple of questions that don’t seem to be answered elsewhere so I was hoping someone here could help.

    I’d like to run five drives (in the current system a pair of 250Gb drives as a software RAID1 array, and three 2Tb drives as software RAID5 for storage). Is the wiring for the 5.25″ bay such that I would be able to put a 5.25->3.5 adaptor in and mount a standard 3.5″ drive there? And would the machine accept this (i.e. are there no hardcoded limitations in the BIOS that make it demand an optical drive on that channel by an optical drive)?
