Virtual SAN is a distributed layer of software that runs natively as part of the ESXi hypervisor. Virtual SAN aggregates local or direct-attached storage disks in a host cluster and creates a single storage pool that is shared across all hosts of the cluster. Virtual SAN eliminates the need for external shared storage and simplifies storage configuration and virtual machine provisioning operations.
In addition, Virtual SAN supports VMware
that require shared storage such as high availability (HA), vMotion, and distributed resource scheduling (DRS) for failover. More information on Virtual SAN can be obtained from the Virtual SAN Design and Sizing Guide.
