We are using VSAN in our private cloud environment to provide highly redundant CSVs to a Hyper-V Cluster. We are using a converged environment so we have two commodity grade servers setup as a highly available StarWind cluster, then we have numerous Hyper-V compute nodes which access CSVs from the StarWind cluster.
We are able to use Veeam to backup and replicate the VM files from the CSV/cluster.
We use off the shelf 10 GbE SPF+ modules and off the shelf 10 GbE switches. With MPIO, we were able to create a redundant network infrastructure to support our SAN network.
