7 Appendix B: Product BehaviorThe information in this specification is applicable to the following Microsoft products or supplementalsoftware. References to product versions include released service packs:•Windows Server® 2003 operating system•Windows Server® 2003 R2 operating system•Windows Vista® operating system•Windows Server® 2008 operating system•Windows® 7 operating system•Windows Server® 2008 R2 operating systemExceptions, if any, are noted below. If a service pack or Quick Fix Engineering (QFE) numberappears with the product version, behavior changed in that service pack or QFE. The new behavioralso applies to subsequent service packs of the product unless otherwise specified. If a productedition appears with the product version, behavior is different in that product edition.Unless otherwise specified, any statement of optional behavior in this specification that is prescribedusing the terms SHOULD or SHOULD NOT implies product behavior in accordance with the SHOULDor SHOULD NOT prescription. Unless otherwise specified, the term MAY implies that the productdoes not follow the prescription. Section 1.3: The Virtual Disk Service Remote Protocol is implemented by the Windows VirtualDisk Service (VDS) on Windows Server 2003, Windows Server 2003 R2, Windows Vista, WindowsServer 2008, Windows 7, and Windows Server 2008 R2. This protocol is supported on WindowsServer 2003, Windows Server 2003 R2, Windows Vista, Windows Server 2008, Windows 7, andWindows Server 2008 R2. Windows XP and Windows 2000 do not support VDS, but the DiskManagement Remote Protocol [MS-DMRP] on those operating systems provides a subset of thefunctionality that VDS provides. Section 1.6: Windows 2000, Windows XP, and Windows Server 2003 implement DMRP, asspecified in [MS-DMRP]. Windows Server 2003, Windows Server 2003 R2, Windows Vista, WindowsServer 2008, Windows 7, and Windows Server 2008 R2 implement the Virtual Disk Service RemoteProtocol. The VDS Remote Protocol is the preferred protocol to use with Windows Server 2003,Windows Server 2003 R2, Windows Vista, Windows Server 2008, Windows 7, and WindowsServer 2008 R2. The interfaces that are associated with DMRP, as specified in [MS-DMRP], are notavailable on Windows Vista, Windows Server 2008, Windows 7, or Windows Server 2008 R2. Section 1.7: There is no optional support of interfaces, but a server which is compliant to aspecific Windows Server version is required to implement all interfaces supported by thatWindows Server version.Interfaces common to all storage object management.The following table lists, by operating system version, the interfaces common to all storagemanagement.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011334 / 360
