Chapter 2 Description
I/O Management Units
Scalar i6000 User’s Guide 22
Control Management
Blade (CMB) 2
The CMB performs unit status monitoring, including power and I/O
present conditions, and internal network switch functions connecting
I/O blades with the LMM. The CMB stores connec
tivity information for
the I/O blades so that if you switch out an I/O blade, you do not have to
reconfigure connectivity settings to drives. The CMB also enables you to
update a drive’s firmware without using a firmware update (FUP) tape.
FC I/O Blades 2
There are two different FC I/O blade types: 6404 that auto-negotiates up
to 2 Gbps and 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
DLT-S4, and SDLT-600 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
drive to a blade; the I/O blade supports only 4
gigabits per second, but the drive supports 8
gigabits per second.
Ethernet Expansion
Blade (EEB) 2
The Ethernet Expansion Blade (EEB) provides the option for Ethernet
connectivity to each LTO-5 drive for MCB-to-drive communication
purposes only. The EEB is not in the data path like the fibre I/O blade.
The connection is at T100. This 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 drives. The EEB provides Ethernet connectivity to the library's
internal Ethernet and should not be connected to an external Ethernet
source.
