This VMware vSAN design is limited to the management cluster only. The design uses the default Storage Policy to achieve redundancy and performance within the cluster.

VMware vSAN Conceptual Design

While vSAN can be used within the shared edge and compute cluster, this design currently gives no guidance for the implementation.

vSAN Logical Design

In a cluster that is managed by vCenter Server, you can manage software-defined storage resources just as you can manage compute resources. Instead of CPU or memory reservations, limits, and shares, you can define storage policies and assign them to virtual machines. The policies specify the characteristics of the storage and can be changed as business requirements change.
