9.2. Hardware Providers
To support advanced management of iSCSI virtual disks and snapshots, you
can use the following hardware providers, which come preinstalled on the
Viking Series NAS applaince:
• Microsoft iSCSI Software Target Virtual Disk Service Hardware
Provider
Microsoft Windows Server 2003 introduced Virtual Disk Service (VDS), a set
of application programming interfaces (APIs) that provides a single interface
for managing disks. VDS provides an end-to-end solution for managing
storage hardware and disks, and for creating volumes on those disks. The
Microsoft iSCSI Software Target VDS Hardware Provider is required to
manage virtual disks on a storage subsystem.
You install the Microsoft iSCSI Software Target VDS Hardware Provider on
each iSCSI initiator computer running a storage management application
(such as Storage Manager for SANs) that uses the hardware provider to
manage storage.
• Microsoft iSCSI Software Target Volume Shadow Copy Service
Hardware Provider
iSCSI snapshots are created using Volume Shadow Copy Service and a
storage array with a hardware provider designed for use with Volume
Shadow Copy Service. A Microsoft iSCSI Software Target VSS Hardware
Provider is required to create transportable snapshots of iSCSI virtual disks
and create application consistent snapshots from iSCSI initiators.
You install this hardware provider on the iSCSI initiator server and the server
that is to perform backups. The backup software you use must support
transporting snapshots.
