In Windows 2000, each storage area network (SAN) hardware vendor provided its own proprietary set of APIs for managing their hardware. This makes it challenging to develop uniform SAN-management software. Windows Server 2003 addresses this issue with VDS. 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. With this abstraction layer provided by VDS, Windows Server 2003 gives customers a more robust set of solutions, including greater flexibility for making long-term investment decisions regarding SANs and other storage options.
Management applications no longer need to take into account the specific hardware being targeted. Instead, by developing applications that target VDS, the next generation of Windows disk management applications will be able to manage any hardware that has a VDS provider.
