We are using VSAN in our cloud environment to provide CSVs to the Hyper-V Group. We are using a converged environment, so we have two commodity class servers configured as a high availability StarWind cluster and then we have many Hyper-V compute nodes that access the CSVs from the StarWind cluster.
We can use Veeam to back up and replicate the virtual machine files from the CSV/cluster.
We use SPF + 10 GbE modules off the shelf and 10 GbE switches off the shelf. We were able to create a redundant network infrastructure to support our SAN network.
