Secure Storage Assignment
SAN Manager LM provides SAN storage access control at the device or logical unit number
(LUN) level. The storage security provided by SAN Manager LM enables users to build and
manage complex SANs with heterogeneous servers and storage devices. IT managers can
confidently assign storage to one or more hosts and be assured that no other hosts have
access to the devices.
SAN Manager LM allows the IT manager to view and manage an entire SAN from one
centralized console. An intuitive graphical user interface with drag-and-drop capabilities
makes storage assignment fast and accurate. Storage assigned exclusively to each host is
clearly displayed in a simple tree structure. SAN Manager LM also provides a powerful,
error-free way to visualize and manage storage configurations where more than one host
must access the same device(s), which makes it invaluable for cluster server and shared
tape environments.
Security starts at boot time for each host with SAN Manager LM, which ensures that no
other drivers, services, or applications can access unassigned storage at any time. Only
authorized users can open and use the SAN Manager LM administration application.
Access is enforced through conventional network security. IT managers must be
authenticated by network logon procedures and be a member of a group that is granted
SAN administration rights.
Storage When and Where It Is Needed
There is never a good time to make system configuration changes in business critical
environments. Downtime needed to physically reconfigure systems comes at a very high
cost and must be minimized. The alternative is to use SAN Manager LM to logically assign
storage when and where it is needed, 24 hours a day, 7 days a week. The simple drag-and-
drop interface enables storage to be added/removed/assigned in a matter of seconds
because no host reboots are required. When LUNs containing Windows NT file systems are
moved, SAN Manager LM automatically mounts the associated file systems so they will be
