Virtual Storage Area Network (VSAN) on ESXi 6

For shared storage, no need for separate dedicated storage solution.

Each ESXi hosts contributes some of the disk storage resources.  Minimum of 3 ESXi hosts required.
SSD drive is recommended.  In vSphere 6, all drives can be SSD or flash.  More flash disks means better performance and more HDD means more datastore capacity.

A logical virtual SAN datastore to store VM files .

VSAN requirements:

* At least 3 ESXi hosts
* VMKernal ports enabled for VSAN - Create a dedicated VMKernal port for VSAN on standard or distributed switch with plenty of uplink bandwidth.
* Cluster enabled for VSAN.  Virtual cluster must contribute at least 1 flash disk. Number if HDD disk host contributes must be >= to number of flash disk it contributes.
* Create disk groups
* Allocate disks




 For each ESXi host, VMKernal ports enabled for VSAN - Create a dedicated VMKernal port for VSAN

 Cluster enabled for VSAN (Temporarily, Turn off vSphere HA to turn on/off virtual SAN)

Create disk groups

Select eligible disks
