> Is there a reason why the SOL console is prefer on the standard console?
Because the console on the serial port allows one to manage systems as if
physically there... from another continent.
Couple serial console with IPMI power on/off and reset, and unless the hardware
busts, it can be managed from anywhere.
Hardware solutions which provide video, mouse and keyboard multiplexing are
often OS dependent, do not work well with all operating systems, or do not work
at all.
Video and mouse are utterly useless when one has distributed datacenters with
hundreds of thousands of hosts in each. You physically cannot click fast enough
in enough GUI's to maintain systems on such a massive scale.
Serial console, on the other hand, is plain ASCII interface. And that *can* be
automated, but the best part is that it requires no extra software whatsoever
if done exactly as I recommended earlier. It just works.
