vSAN 6.0 or later scales up to 64 nodes per cluster for both hybrid and all-flash architectures and matches vSphere node/cluster supportability. You can scale up to 200 virtual machines per host and 6400 virtual machines per cluster, for both hybrid and all-flash architectures. The maximum virtual disk (VMDK) size is 62 TB, matching classic VMFS/NFS VMDK size.
