We have 3 hyper-v servers in a cluster using CSV's, one each. About 70 VM's and each server has the capacity to take on all VM's if needed. They are using a Clarrion CX3-20 SAN for storage.
We will replace our current SAN with an EMC VNX 5300 this year.
We now want to create a DR solution and need to know the best/easiest way to do it. Our current solution is restoring from Data Protection Manager which works but is a very slow process.
We have a 60K budget, enough servers to handle the load and a 20 Mbps pipe to the DR location.
I am looking at 2 methods but would like to get more input.
1 - Buy a second VNX 5300 and do SAN-SAN replication but I have no idea how to do multi-site clustering using CSV's. It looks like are no solutions for this.
2 - Put the CX3-20 SAN we are replacing in the DR location and use something like Steeleye to do the replication. In a DR situation, just bring up the VM's, change the IP's and DNS records.
My question is, what would you do? The best solution would also include something for SQL which we currently use mirroring. The SQL portion is not critical as mirroring works great but maybe there is something better which would be included with the Hyper-V solution??
