Virtual Disk Service (VDS)
Virtual Disk Service (VDS) implements a single, uniform interface for managing disks. Each hardware vendor writes a VDS “provider” that translates the general purpose VDS APIs into specific instructions for their hardware (Targeted for Storage Area Network(SAN) ).
Microsoft has implemented VDS providers for basic and dynamic disks. This brings functionality to basic disks, such as online growth, that formerly only applied to dynamic disks.
