[Beowulf] console hardware?

[Simen Thoresen]

Hi Guys,

How does one handle console-logging thes days?

We run a development environment with a number of small clusters of 
different shapes and some tens of pc- and non-pc type nodes (mostly with 
Linux) that our developers keep crashing. It would be very useful to hook 
something up to the nodes to have their last screens of console-output be 
available, after the fact. Is serial-console and kermit the way to do it, or 
  is someone building and/or selling more modern solutions? Preferrably, 
we'd like to just log into a concentrator and be able to read the last 
several screens logged by the just crashed node.

What are your experiences and recommendations?

Any vendors please reply off-list.

Yours,
-S
