Re: Storage Migration and Expensive SAN's
I go more in depth into local storage in upcoming articles.
As to exploring other alternatives; I can't afford VMWare. I can only afford to review MS because of technet. Open source virtualiation options will be reviewed...but I lost two servers and my SAN towards the end of the Microsoft review. I have to buy expensive replacement equipment to properly do those reviews...something I have to put off until after my wedding in July.
My VMWare testing tends to occur when I can borrow a buddy's lab who has licences. (I got time on the lab for the duration of the MS cloud eval.) Thay lets me see what VMWare can do...not how easy it is to set up.
The one thing I can tell you about MS is this; "zero to hyper-v private cloud in a few clicks" is not exactly exaggeration. I can build a fully SaaS ready MS-based private cloud in about 1/2 hour, if I have good gear.
Based on my useage of production envrionments, my "state of virtualisation" impression is this: MS were playing catch-up last round. This round, I think they might just be a few steps ahead. (They certainly are in storage!) Openstack and KVM are decent IaaS offerings, but have quite a bit of catch up to do to reach MS or VMWare anywhere else.
