Virtual volumes are objects exported by a compliant storage system and typically correspond onetoone
with a virtual machine disk and other VM-related files. A virtual volume is created and manipulated outof
band, not in the data path, by a VASA provider.
A VASA provider, or a storage provider, is developed through vSphere APIs for Storage Awareness. The
storage provider enables communication between the ESXi hosts, vCenter Server, and the
vSphere Web Client on one side, and the storage system on the other. The VASA provider runs on the
storage side and integrates with the vSphere Storage Monitoring Service (SMS) to manage all aspects of
Virtual Volumes storage. The VASA provider maps virtual disk objects and their derivatives, such as
clones, snapshots, and replicas, directly to the virtual volumes on the storage system.
