Oh and for this..
Where can I best install the hypervisior?
Most enterprises use SD cards or USB drives to host the hypervisor. It's a lot cheaper than sticking in HDD's when your data is on a SAN, but it should demonstrate that the hypervisor disk is barely ever accessed once it's booted and its performance is a non-issue. I keep running into consultants throwing two SSDs in a RAID mirror just for a hypervisor and all I can pin it on is, someone's used to consulting for Hyper-V.
