VSAN Architecture Contd.

Full integration with HA, DRS, Horizon View (including Linked Clones), and SR

Storage Policies assigned at the VM (Storage Policy Based Management) vCenter and ESXi hosts running 5.5 U1

Managed with vSphere Web Client

Minimum of 3 hosts with minimum 1 SSD and 1 HDD

If more than 3 hosts are in the cluster then not all hosts need to contribute stora

Maximum of 32 hosts per cluster, 32,00 VMs, 5 disk groups per host, each disk

has maximum of 7 HDD and 1 SSD

Object-based storage with VMFS-L file system Single VSAN datastore per cluster and thin-provisioning is enforced by default

Does Not Support Storage I/O Control, Datastore Clusters

VSAN Uses Includes: Management Cluster, DMZ, Remote Office, VDI, DR, Tie

& Dev
