This article shows how to enable a VMware Virtual SAN (VSAN) cluster within VMware vSphere. If you are unfamiliar with VSAN, and what it is, I recommend reading the following articles. Duncan Epping’s Tech Preview of Distributed Storage Cormac Hogan’s Distributed Storage Tech Preview Lets start off by looking at the Pre-requisites of VMware VSAN, what do we need in place before we begin the configuration. Pre-requisites There are a number of pre-requisites that are needed, prior to configuring a vSphere cluster to participate as a VSAN. The following list shows the minimum requirements to implement a VSAN. Minimum of three hosts. Each storage* host has a minimum of one SSD and one spindle hard disk. Each storage* host has a Pass-thru RAID controller as specified in the HCL. The RAID controller must be able to present disks directly to the host without a RAID configuration. 10GB Network. (1GB network can be used for smaller environments, however 10GB is recommended). VSAN VMkernel port configured on every host participating in the cluster. Dedicated VSAN VLAN configured following the recommended vMotion best practices. dVswitch or standard vSwitch with Management port group created. Note: * The term storage used here determines hosts that
