The Cloud Native Storage server resides in vCenter Server:

* Provisions and manages life cycle operations for container volumes

*Creates First Class Disks (FCDs) to support the container volumes

* First Class Disks exist as .vmdk and -flat.vmdk files on a vSphere datastore *

Integrates with storage policy based management (SPBM) for the placement of disks

A First Class Disk (FCD) is also called an improved virtual disk. It is a named virtual disk that is unassociated with a VM. These disks reside on a VMFS, NFS, or vSAN datastore and support container volumes.

Storage policy based management (SPBM) is a vCenter Server service that supports provisioning of persistent volumes according to specified storage requirements. After provisioning, the service monitors compliance of the volume with the required policy characteristics.
