HP StoreEver ESL G3 Tape Libraries - Manual (Page 17)

Host Attachment
Requests issued from the host application result in cartridge movement in the library. The primary
requests issued are for mounting and dismounting cartridges in and out of the tape drives and for
importing and exporting cartridges in and out of the library. The library manages the physical location.
In addition to requesting cartridge movement in the library, the host application can use the Fibre
Channel (FC) command interface to obtain status information, configuration information, and cartridge
storage information from the library.
Tape drives are directly attached to host systems or to the SAN. The library robot control path is
presented through one or more tape drive ports, depending on Partitioning and Failover configuration.
FC drives can be directly attached to host systems or to the SAN. In these configurations, the
management control blade (MCB) has one library control port connecting to the controlling host
computer.
Remote Management
The library can be managed locally or remotely using the LMC. Locally, the LMC appears on the OCP
on the front of the library. Remotely, the LMC is accessed through a client instance of the LMC software
on any computer on the network. For more information about access, see
Logging On From the Library
Management Console (LMC) Using a Web Browser . For more information about the LMC, see
Accessing the Library Management Console (LMC) .
The LMC provides additional monitoring of a SAN-attached library over the network to a management
server by using Simple Network Management Protocol (SNMP). This includes library subsystem health
and status information and early fault notification.
The library also supports the Common Information Model (CIM) server based on the Storage
Management Initiative Specification (SMI-S) on the MCB. A CIM client can use the CIM server to
monitor the SAN-attached library.
Capacity on Demand
ESL G3 tape libraries can be purchased at starting points of 100, 300, 700, 1500, 3000, or 5000
cartridge slots enabled. Adding physical Expansion Modules does not automatically enable new slots.
Instead, slots are flexibly enabled for use in groups of approximately 100 through capacity upgrade
licenses.
Control Module
All library configurations include the control module, which contains the following components at a
minimum (see
Figure 2 ):
• Library management module (LMM)
• I/E station
• Tape drives
• Cartridge storage
• Operator panel
