Virtual Disk Service
The Microsoft Virtual Disk Service (VDS) is a component of the Windows
operating system. The VDS component utilizes third-party vendor specific
software modules, known as providers, to access and configure third-party
storage resources, such as MD3600i Series storage arrays. The VDS
component exposes a set of application programming interfaces (APIs) that
provides a single interface for managing disks and other storage hardware.
The MD3600i Series VDS Provider enables Windows tools, including the
Disk Manager, to access and configure storage array virtual disks.
The VDS Provider for the MD3600i Series storage arrays is available on the
MD3600i Series resource media. For more information on VDS, see
microsoft.com.
Volume Shadow-Copy Service
The Microsoft Volume Shadow-copy Service (VSS) is a component of the
Microsoft Windows operating system. The VSS component utilizes third-
party vendor specific software modules, known as providers, to access and
utilize snapshot and disk copy functionality provided by third-party storage
resources, such as MD3600i Series storage arrays. The combination of the
VSS component and the VSS Provider, included on the MD3600i Resource
media, enables the MD3600i Series storage arrays to be utilized by third-party
and Windows backup and snapshot applications.
NOTE: Virtual disks used as source virtual disks for VSS snapshots must have
names no longer than 16 characters.
The VSS hardware provider uses the source virtual disk name as a prefix for
the snapshot and repository virtual disk names. The resulting snapshot and
repository names are too long if the source virtual disk name exceeds 16
characters.
