VMware Virtual SAN is a software-defined storage technology that is available with vSphere 5.5 Update 1 (or later). Virtual SAN is a core component of vSphere that aggregates local server-attached storage (local storage on a vSphere host/server) and provides a datastore that is visible to all hosts within a vSphere cluster. VMware Virtual SAN is optimized for use with Horizon View 5.3.1.
Virtual SAN implements a policy-based approach to storage management. These policies define virtual machine storage requirements, such as capacity, performance, and availability. Storage is provisioned and automatically configured according to these policies.
The above characteristics of the Virtual SAN architecture are highly beneficial to virtual desktop environments that use Horizon View 5.3.1. Further, the architecture supports standard vSphere features that require shared storage, such as HA, vMotion, and DRS. Virtual SAN eliminates the need for an external shared storage infrastructure and simplifies storage configuration and virtual machine provisioning activities.
