My friend Google pointed me to this:
We constructed a console server for the following reasons:
1. we can reboot servers from home by dialing in (even from prom mode).
2. Get rid of machine room clutter (monitors and keyboards everywhere).
Now we have one monitor and one keyboard.
3. Now we can grab the console of any machine remotely. Even if the
machine is network unreachable.
4. We can now have all the servers (Sparc 10's and 20's, etc) rack
mounted and get rid of cables everywhere.
5. We wanted something that was ASCII based so that we could login from
home.
6. We wanted security, so that not just any user could grab our
consoles.
7. We wanted scrollback. On a traditional server/console (servers
scattered around on tables all with monitors) if your machine
panics while nobody is in the room, you are very likely to lose
all the panic information off the top of the monitor. This can
also be a problem with some of the hardware based console
servers that you may see advertised in the backs of magazines.
With the console server and screen, this won't happen and you
can set scrollback as large as you want.
