LTO -8 Dri ve
When connecting to a Fibre Channel network, LTO-8 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-8 SAS drives attempt to connect at 6 Gb/second, but auto-negotiate
down to 3 Gb/second or 1.5 Gb/second, depending on the requirements of
the port to which the drive is connected.
