BTW I do hear you on ESXI. But my customer will be doing some base level maintenance and they are going to be most comfortable with an MS interface.
Yes, I still think that I'd prefer ESXi, but I think Nutanix CE is even better - it has many of features of VMWare EVO:RAIL platform, but they done much better - aka and best part, I think I said it before - it's free.
Since you're a Cisco guy, this might be interesting for you:
I started my career in MS infrastructure, but it's no longer interest me, I mean I still do Active Directory and related stuff, but without mundane stuff like basic user management. With time I'm trying to concentrate on Virtual system (mostly VMWare) and storage.
VSAN and Nutanix are exciting to me as they represent sort of new idea - hyper-converged infrastructure.
No need for SANs. With virtual switches growing fast with new feature - it's not too long until very expansive (and expensive
) Cisco networking stuff might no longer be needed for most part.
