VMWare vSAN is used on the management cluster nodes to provide associated management VMs with fault-tolerant storage. With this configuration, the applications and VMs that depend on underlying node-failure protection can do so seamlessly by using vSphere's high availability.

The vSAN cluster includes eight Disk Groups across the cluster, with two Disk Groups per ESXi node. Each Disk Group has a single NVMe drive for caching and three 1.6 TB NVMe drives for capacity. The vSAN cluster is further defined by the following configuration attributes:
  • All-Flash, FTT=1 Configuration
  • Stripe-Width=3
  • Reserve (Slack) Capacity = 20%

This configuration provides 15 TB (uncompressed) for application use. The capacity within the management cluster is oversized to provide for the automatic rebuild of vSAN objects following node failure and to make sure the cluster can accommodate future Vantage applications requiring a fault-tolerant configuration within the system.
