Hi,
We currently use a Windows 2008 R2 Hyper V Cluster. Because we wanted to migrate virtual machines from one node to another, we installed a shared storage box based on iSCSI. One of the new features of Windows 2012 is live migration without the requirement of shared storage. This sounds great because our rack space is very limited. Being able to remove the storage box with it's complexity, great... Only, I noticed from a few other posts, that you still need clustering if you require live migration to happen when one node fails. This is a feature that we rather not like to miss, except if we can work around it with Hyper V Replica for example?
Our current scenario is as follow: the virtual servers are balanced between two nodes on one physical location, when one node fails, we want them to be available on the other node until the other node is available again. Our nodes are provisioned that they can handle the increased load of hosting all virtual servers for a limited time on one node.
Is it a good idea to use Hyper V Replica for this scenario. What will we exactly miss (pro/cons) compared to our current scenario? Are there other disadvantages/advantages or maybe other solutions? The main goal is to get around the shared storage and remove the complexity and cost (rack space/power consumsion).
Thank you.
