So two nodes is the small end for a hyperconverged appliance (or one that you build yourself with hypervisor + Starwind VSAN), I think I'm clear there. But what about upper limits? A lot of hyperconverged appliances cap out around ten or twelve nodes in a single cluster. What are the limites from the Starwind side if I'm building Hyper-V or VMware clusters? Is it the same and a Starwind limitation? Do I just get to go to the limit of the hypervisor?
With VMware we can push it to the limit of 64 nodes using VVols. With Hyper-V, in theory, StarWind handles 64 nodes just fine, but the best practises of Microsoft suggest 1 CSV per node, which means 64 CSVs, which means one very sad IT admin with a twitching eye and chronic headaches.
The short version would be: from our side, the hypervisor is the limit.
That would split up failure domains pretty heavily, though. Impacts to one part of the cluster would not ripple through to other parts.
But imagine the poor sysadmin who has to configure 64 CSVs... shudder
