Reducing many terminal consoles to a single workstation

[Arnold de Leon]

Here is the problem:  We want to reduce a dozen terminals currently
acting as consoles for a dozen file servers in our machine room to
a single workstation.

I am currently investigating using a workstation with enough
serial ports as console for the file servers.  I expect to
be running something like X on the workstation.  The idea is
I can open windows to any of the machines as needed.
The "console" can also do some for logging if desired.

Has anyone done anything similar to this.  Does anyone sell
something like this?  I believe DEC sells a workstation console
for its VAXclusters.

Any pointers, suggestions, hints before I'm in too deep?

Thanks.
