Storage design for VMware Cloud Foundation includes the design for principal and supplemental storage.

Principal storage is used during the creation of a workload domain and is capable of running workloads. Supplemental storage can be added after the creation of a workload domain and can be capable of running workloads or be used for data at rest storage such as virtual machine templates, backup data, and ISO images.

Special considerations apply if you plan to add clusters to the management domain, for example, to separate additional management components that require specific hardware resources or might impact the performance of the main management components in the default cluster, or, in the case of the consolidated architecture of VMware Cloud Foundation, to separate customer workloads from the management components.

VMware Cloud Foundation supports the following principal and supplemental storage combinations:
