VMware Virtual SAN Scalability Limits – VSAN

I have had a few questions off people recently asking what are the scalability limits of the new VMware Virtual SAN.  I thought I would post a quick table to show these. Description Limit Maximum number of disk stripes 12 Maximum number of failures tolerated 3 No of VSAN hosts per Cluster 8 Max number of IOps 120,000 Max number of Parallel vMotion per VSAN cluster 8 Max number of Parallel SvMotion per VSAN cluster 2 Max number of VMs per host 100 Max number of VMs per (evenly distrubted) VSAN cluster 800 Max number of disk groups per host 5 Max number of hard disks per disk group 6 Hopefully by providing these numbers, if you are thinking about implementing VMware Virtual SAN in your environments it will help you with the design.  Please remember that with the release of VMware vSphere 5.5, the VMware Virtual SAN product is in public beta (meaning it is not supported in production).

Duncan Epping has also written a nice article on design considerations on VMware Virtual SAN.
