LTO-9 Drive
When connecting to a Fibre Channel network, LTO-9 Fibre Channel drives will
attempt to connect at 8 Gb/second, but will auto-negotiate down to 4 Gb/second, or
2 Gb/second, depending on the requirements of the port to which the drive is
connected.
LTO-9 SAS drives attempt to connect at 12 Gb/second, but auto-negotiate down to 6
Gb/second or 3 Gb/second, depending on the requirements of the port to which the
drive is connected.
