Figure 9 Ports on the HP StorageWorks Interface Manager card
The Interface Manager card communicates with the management station over the LAN. The management
station is a Microsoft® Windows®-based PC (server) that hosts the Command View TL software. Ideally,
the management station should have a static IP address, and be dedicated for use with the Interface
Manager card and Command View TL software.
Any client machine on the LAN can communicate with the Interface Manager card either through the
GUI or through a command line interface (CLI). At a higher level, multiple libraries, each containing an
Interface Manager card, can be connected to a single management station. Each Interface Manager
card can communicate with only one management station, but the management station can communicate
with multiple Interface Manager cards.
After being configured, the Interface Manager card is used to configure the interface controllers based
on knowledge of the library and SAN. As robotics commands are received from the interface controllers,
the Interface Manager card acts as a switch to relay these commands to the library robotics controller.
The Interface Manager card contains on-board Flash memory to provide a persistent history of the library
and storage network health.
Interface controller
The interface controller is an HP proprietary card that provides FC connectivity for LTO2 and LTO3 tape
drives and robotics in the SAN. LTO4 tape drives do not connect to an interface controller; instead,
they connect directly to the SAN. Libraries that contain only LTO4 tape drives still need one interface
controller which is used to direct commands to the robot. Commands, data, and status information
are transferred to and from this controller, from hosts, the robot, and the LTO2 and LTO3 tape drives.
One interface controller can manage up to four LTO2 or LTO3 tape drives. The interface controller is
available in two speeds: 2 Gbps and 4 Gbps.
