Hi,
I'm planning a cluster server for file storage. I have read about the new high availability feature in Windows 2012, which extends the classic failover to a sort of an active-active file server cluster.
My question is the following: in a classic failover cluster, it was neccesary a shared storage, and then, one of the cluster nodes gave service to that storage. Now, with this new feature, I don't know if still works with shared storage, or like a DAG Exchange cluster, each node needs its own storage, and the content of all resources is synchronized.
Also, I want to know if is possible to combine the failover and continuous avaliability in a single cluster. I mean, if it is mandatory for continuous availability that each node has its own storage, this duplicate the need of storage space. So we would only use it for critical data: the rest of resources, would be used in a shared storage in an active-pasive mode cluster. Can live both together in the same cluster?
Thank you
