There is one Fibre Channel (FC) I/O blade type supported: 7404 that
auto-negotiates up to 4 Gbps. The 7404 FC I/O blade has an embedded
controller that provides connectivity and features that enhance the
performance and reliability of tape operations. It also provides two host
communication ports and four connection ports to drives.)
• Fibre Channel LTO-1, LTO-2, LTO-3, LTO-4, LTO-5, LTO-6 and
LTO-7 drives can be connected to drive-aggregating Fibre
Channel I/O blades or directly attached to a host, so these drives
do not require an external SNC.
• We recommend that you do not connect an LTO-5 or later drive
to an FC I/O blade. These drives support speeds of 8 Gbps, but
the FC I/O blade only supports 4 Gbps.
The Ethernet Expansion Blade (EEB) provides the option for Ethernet
connectivity to each LTO-5 or later drive (for MCB-to-drive
communication purposes only). The connection is at T100. 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 LTO-5 or later drives. The EEB
provides Ethernet connectivity to the library's internal Ethernet only and
should not be connected to an external Ethernet source.
