Advice on fully redundant Hyper-V cluster

[enealDC]

Your mileage varies with whether or not I/O gets broken, but I've tested some settings for my customers that have overcome this issue for some workloads.

I do have some concerns about what "DSS V6 will break i/o operation performed on the DSS V6 iSCSI target e.g. copying of files" really means in a real-world Hyper-V environmnet.

I hope to find out some time later this month. Right now I am waiting for a good time to move my current VMs off to a temporary third Hyper-V server while I build/test the cluster environment. During a catastrophic SAN failure, I could live with the VMs actually "crashing" and then restarting from the redundant SAN. 100% uptime is not a requirement for our environment; I'd just like to minimize any downtime.

I'll do some forum searches and look at your tips!

Well what it's trying to say is that when a failover occurs that there is a risk of IO operations being broken.
DSS isn't just breaking stuff randomly
