[MS-VDS]: Virtual Disk Service (VDS) Protocol Specification

Figure 1: Relationships between VDS remote protocol objectsService Loader and Service: The first interface the client obtains is the IVdsServiceLoaderinterface. The client invokes IVdsServiceLoader::LoadService to load the VDS service on thespecified machine. The server responds with an IVdsService interface for the VDS service that isloaded.Service and Providers: The client invokes IVdsService::QueryProviders to obtain a list ofproviders. The server responds with an IEnumVdsObject interface, which enumerates a list ofIUnknown interfaces, one for each provider that is available on the server. The client invokesQueryInterface on the IUnknown interface to retrieve a IVdsSwProvider or IVdsProviderinterface on the provider object.Service and Subsystems: The client invokes IVdsService::QueryProviders with the flagVDS_QUERY_HARDWARE_PROVIDERS to obtain a list of VDS hardware providers. The serverresponds with an IEnumVdsObject interface, which enumerates a list of IUnknown interfaces,one for each hardware provider that is available on the server. The client invokes QueryInterfaceon the IUnknown interface to retrieve an IVdsHwProvider interface on the provider object. Theclient invokes IVdsHwProvider::QuerySubSystems to obtain a list of subsystems. The serverresponds with an IEnumVdsObject interface, which enumerates a list of IUnknown interfaces,one for each subsystem that is available on the server. The client invokes QueryInterface on theIUnknown interface to retrieve an IVdsSubSystemImportTarget interface.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011143 / 360
