Notes About Point to Point:
- You can use Point to Point if the tape drive is connected
via a switch.

can be configured for speeds of up to 8 Gb/s. If they
are configured for 8 Gb/s, you should connect them
directly to a host and not to an FC I/O blade, because

you connect an LTO-5 Fibre Channel tape drive to an
FC I/O blade, you must configure the tape drive
speed to 4 Gb/s or less.
