Hi Andre,
Thanks for the clarification and advise. I'll try it out first with the single vCenter and see its steps to recover a machine. Hopefully it'll work out fine and if it does then it'll be a great purchase. The Server 2012 has the same replication feature within the Hyper-V interface, I've tried it and its really simple. It does not require any System Center or any replication device/appliance to manage the replication. All you need is two Server 2012 license and your done.
Thanks,
MT Alam.
