The big VMware vSphere 6 launch was yesterday and along with it comes Virtual SAN (VSAN) 6. Here are a couple of good summaries:
Rawlinson Rivera – VMware Virtual SAN 6.0
The big news is that a vSphere cluster will now scale to 64 hosts and thus VSAN will too. So what does that look like fully scaled up and out with the maximum hosts, maximum disk groups, and maximum disks per disk group? By the way, for details on how VSAN scales up and out check Is Virtual SAN (VSAN) Scale Up or Scale Out Storage…, Yes!.
Virtual SAN (VSAN) Enabled vSphere Cluster Scaled Up and Out to 64 hosts (nodes).
Oh yea, the overall VSAN performance is significantly improved. Plus with double the number of hosts that doubles the performance. In addition, VSAN now supports an All-Flash configuration that even further increases the performance.
