Designing VSAN for virtual machine storage

VMware Virtual SAN (VSAN) is integrated into the ESXi hypervisor. VSAN virtualizes and aggregates the local direct-attached disks in ESXi hosts. This creates a single pool of storage resources from the local disks with each host that is shared across all hosts in the VSAN cluster, as shown in the following diagram:

VSAN diskgroups

How to do it...

To use VSAN for storage in a vSphere virtual infrastructure design, follow these steps:

1. Identify the hardware requirements to support VSAN
2. Verify that the disks and controllers are on the VSAN Hardware Compatibility List (HCL)
3. Size VSAN to support performance and availability
4. Enable VSAN on the vSphere Cluster
