This topic summarizes characteristics that apply to Virtual SAN, as well as its clusters and datastores.

Virtual SAN provides numerous benefits to your environment.

Table 1. Virtual SAN Features

Supported Features


Shared storage support

Virtual SAN supports VMware features that require shared storage, such as HA, vMotion, and DRS. For example, if a host becomes overloaded, DRS can migrate virtual machines to other hosts in the cluster.

On-disk format

Virtual SAN 6.5 supports on-disk virtual file format 3.0, that provides highly scalable snapshot and clone management support per Virtual SAN cluster. For information about the number of virtual machine snapshots and clones supported per Virtual SAN cluster, see the Configuration Maximums documentation.

All-flash and hybrid configurations

Virtual SAN can be configured for all-flash or hybrid cluster.

Fault domains

Virtual SAN supports configuring fault domains to protect hosts from rack or chassis failure when the Virtual SAN cluster spans across multiple racks or blade server chassis in a data center.

Stretched cluster

Virtual SAN supports stretched clusters that span across two geographic locations.

Virtual SAN health service

Virtual SAN health service includes preconfigured health check tests to monitor, troubleshoot, diagnose the cause of cluster component problems, and identify any potential risk.

Virtual SAN performance service

Virtual SAN performance service includes statistical charts used to monitor IOPS, throughput, latency, and congestion. You can monitor performance of a Virtual SAN cluster, host, disk group, disk, and VM.

Integration with vSphere storage features

Virtual SAN integrates with vSphere data management features traditionally used with VMFS and NFS storage. These features include snapshots, linked clones, vSphere Replication, and vSphere APIs for Data Protection.

Virtual Machine Storage Policies

Virtual SAN works with virtual machine storage policies to support a virtual machine-centric storage approach. When provisioning a virtual machine, if there is no explicit assignment of a storage policy to the virtual machine, a generic system defined storage policy, called the Virtual SAN Default Storage Policy is automatically applied to the virtual machine.

Rapid provisioning

Virtual SAN enables rapid provisioning of storage in the vCenter ServerĀ® during virtual machine creation and deployment operations.
