Managing Storage in VMware Cloud
Foundation
To
create and manage a workload domain,
VMware Cloud Foundation
requires at least one shared storage type for all ESXi hosts within
a cluster. This initial shared storage type, known as principal storage, is configured during
VxRail first run. Additional shared storage, known as supplemental storage, can be added using
the vSphere Client after a cluster has been created.Although the management domain requires vSAN
as its principal storage, vSAN is not required for VI workload domains or vSphere
clusters.
For a VI workload domain, the initial storage
type can be one of the following:
- vSAN
- Fibre Channel (FC)
This initial
shared storage type is known as principal storage. Principal storage is configured during
the VxRail first run. Once created, the principal storage type for a cluster cannot be
changed. However, a VI workload domain can include multiple clusters with unique principal
storage types.
Additional shared storage types can be added
to a cluster in the management domain or a VI workload domain after it has been created. The
additional supported shared storage options include:
- vSAN
- Fibre Channel (FC)
Additional shared storage types are known as
supplemental storage. All supplemental storage must be listed in the VMware Compatibility
Guide. Supplemental storage can be manually added or removed after a cluster has been
created using the vSphere Client. Multiple supplemental storage types can be presented to a
cluster in the management domain or any VI workload domain.
