Library Overview

Card cage and controllers

The library card cage The library card cage is located in the top of the library cabinet, above cluster 0. It houses up to six FC interface controllers (e2400-160) or native FC interface controllers (e2400-FC 2G), the library robotics controller (e1200-160), a fan, and two power supplies (see Figure 7).

The FC interface controllers translates the Fibre Channel Protocol (FCP) to and from the SCSI protocol, if necessary. It transfers commands, data, and status information to and from FC controllers and FC and SCSI devices.

Supported devices include:

Initiator devices – FC hosts

Sequential access devices – tape drives

Changer devices – tape libraries

The e2400-160 FC interface controller provides bidirectional connectivity for Ultra-3 SCSI buses in a Fibre Channel Switched Fabric (FC-SW) environment.

The e2400-FC 2G interface controller provides fibre connectivity for native FC drives, such as the Ultrium 460-FC drive.
