^^^ That's an example discussion, it's not an absolute specification... 
But it is a good specification of features (if any other product or set 
of products can achieve similar).

Obviously I don't care how the SAN works as long as it's fast enough - 
but vSAN does look cute as an aside...


  I have probably proved we should DIY as we do now...


Essentially, we MUST have:

VM Console access
Reliable VMs (ie no random shutdowns because the host feels like it)
Firewall
A certain amount of resource (about 220vCPU, 390GB RAM, >7000IOPS)
Straight forward management of the above.
Hot migration for host and datastore (volume)
Some backup/DR solution that works with the above.


Nice to have - resource control/limiting on a VM basis.


These are things I'm not prepare to compromise on -
How's Xen with respect to those (specifically hot migration and console 
access to both Windows and Linux VMs)? It's been a long time and my 
experience with Xen has not been happy previously.


(we'll allow the firewall to be external as VMWare's vShield is a bit 
special but it's not the only way to get a border firewall).



Cheers
