MD Storage Manager
The MD Storage Manager provides the perfect combination of robustness and ease-of-use—two attributes
not commonly found together in an entry-level storage management tool. The new MD Storage Manager
graphical user interface (GUI) is ideally suited for the full-time storage administrator, who wants complete
control over their storage configuration, as well as the part-time system administrator, who needs an
intuitive interface that helps them ensure optimal storage utilization.

MD3200 Series Storage Manager Software Packages
The MD3200 series Storage Manager software contains the following four packages:
Client – This package contains the graphical user interfaces (GUI) for monitoring and managing the storage
arrays. It also contains an optional monitor service used to send alerts when there is a critical problem
with the storage arrays.
Utilities – This package contains several providers to simplify integration with Microsoft tools (VSS and VDS)
rd
and integration to 3
party management tools that take advantage of SMI-S protocols.
Agent – This package contains software that allows a storage management station to communicate with the
controllers in the storage array over the I/O path of a host.
Failover Driver – This package contains the multi-path driver used to manage the I/O paths into the
controllers in the storage array. If there is a problem on the path or a failure of one of the controllers, the
driver automatically re-routes the request from the hosts to the other controller in the storage array.
