Hi all -
I am in the process of evaluating AlwaysOn and had a question on its use. From what I have read, it sounds like AlwaysOn is only useful when you don't have shared storage (e.g. two data centers without a fast pipe between). I read a lot of people were using AlwaysOn inside a datacenter (i.e. would have shared storage), in place of using a traditional failover cluster.
To me the dependency on double the amount of storage, and the way the replication occurs (asynchronous you have blocking, but data integrity is ensured, vs. synchronous no blocking, but no data intergrity) makes a tradition failover cluster better than AlwaysOn when you have shared storage.
Am I am missing anything, or does what I am stating above sound correct? Is anyone using AlwaysOn that has shared storage? If so, why are you doing that?
Appreciate everyones time.
Thanks,
