Scalar i6000 Planning Guide
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.
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.
