We are pretty small as far as production operations go (less than 75
servers for dev, qa, and prod).  We have 3 Lantronix--1 32 port and
2 16 port.

I think they are worth the extra--but make sure you get good cables
for them.  You *can* get the "break" problem with cheap cables.
You also still have to be careful with unplugging the RJ45's--it can
send a break as well.  (Turn off keyboard input beforehand if you
need to unplug while server is live--you can do this from the OS.)
I am removing the last heads (don't ask, one of the doofus sys
admins before me) off of our Sun servers with a move in a couple
of weeks.

I believe that Cisco serial concentrators will do SSH now, as well.
Last time I checked it was SSH1, but that was several years ago.

This kind of remote access is a *must* if you want to be able to
do your prod support from off-site.  At my last job, I never even
saw my servers--we were co-located (my company's facility)--
so if I absolutely needed "hands on" I used the NOC techs.
