Blade 3
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 connectivity 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 3
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 has six auto-negotiating, 2 Gbps FC data
ports and backplane connections. It provides two host communication
ports and four connection ports to drives.
