Virtual SAN has a number of unique requirements to consider when sizing a server. Servers hosting a Virtual SAN should have fast network speeds, ideally 10 Gbps or multiple 1 Gbps connections. Virtual SAN clusters require a minimum of three hosts with local storage to function. For best redundancy, four or more hosts are recommended as rebuilding of VM redundancy can occur automatically with four servers. Each server requires a minimum of one SSD disk and one spinning disk or two SSD disks. For large storage capacity, we would look for many 2.5" bays or 3.5" bays with hot swap capability.
