This vSAN design is limited to the management cluster. The design uses the default storage policy to achieve redundancy and performance within the cluster. While VMware vSAN can also be used within the shared edge and compute cluster, this design currently gives no guidance for the implementation.

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.

Virtual SAN Storage stores the data of the management applications in the SDDC. While Virtual SAN can be used within the shared edge and compute cluster, this design currently gives no guidance for the implementation.
