From this screen, you can see the transfer speed to the various SCSI devices connected to the controller
based on channel ID, as well as detailed statistics concerning the amount and sizes of files read or
written by that device. By referring to the /proc/scsi/scsi file, we can see that this controller is
communicating with the CD-ROM at 20 megabits per second, while the tape drive is only connected
at 10 megabits per second.
4.3.9 /proc/sys
This directory is special and different from the others in /proc, as it not only provides a lot of infor-
mation about the system but also allows you to make configuration changes to a running kernel.
