Fibre Channel I/O

Blades

There is a single Fibre Channel (FC) I/O blade type: 7404 that auto-

negotiates up to 4 Gbps. Each FC I/O blade has an embedded controller

that provides connectivity and features that enhance the performance

and reliability of tape operations. Each blade provides two host

communication ports and four connection ports to drives.

• Fibre Channel LTO-1, LTO-2, LTO-3, LTO-4, LTO-5, and LTO-6

drives can be connected to drive-aggregating Fibre Channel I/O

blades or directly attached to a host.

Note: If library firmware is at level 630Q or later, DLT tape

drives are no longer supported.

• We recommend that you connect directly to the host FC to take

advantage of the maximum possible throughput.

Ethernet Expansion

Blades

The EEB provides the option for Ethernet connectivity to each HP LTO-5

or LTO-6 drive (for MCB-to-drive communication purposes only). The

EEB provides a control path to the drive for commands as well as

facilitates taking drive logs and downloading drive firmware. Each EEB

has 6 Ethernet ports to allow attachment to 6 HP LTO-5 or LTO-6 drives.

The EEB provides Ethernet connectivity to the library's internal Ethernet

only and should not be connected to an external Ethernet source.
