As Im sure you know Hyper V R2 with live migration isn't due out for production until 2010. Well long story short, I need to implement a solution that will do the same thing now. Currently we run a single Hyper V server with no San, we are ordering another server, and a 4TB pro logic SAN. I know I can set it up to migrate, but I need it to do this on its own with no downtime.
I was looking at VMWare, and if I see the prices correctly, it is out of the question, not to mention I would like to stick with Hyper V. I am open to 3rd party add ons that would make this happen until R2 gets released.
I would also like to look at the option of having a 3rd fail over to a data center, so basically if the building burned down then the VM's would fail over to the data center.
