Isilon serial port management

Question

I am polling members of this community to find out if anyone has set up a remote access system through the back-end serial ports.  For example:  Connected all the node serial ports into a serial hub/controller to allow remote access, much like a KVM/DRAC system.  Many thanks in advance.

We've used OpenGear IM4248s for this sort remote management. Once you start running large clusters (We've run anywhere from 24-78 node cluster(s)) than having this capability is indispensable... Granted this _really_ should be part of the product ala SP or RLM you'd see on competing NAS solutions

i was thinking about it when my cluster was small but then as it grew i could not justify an IP based serial console (14 node cluster). Other then during an upgrade watch POST, not sure you can get much out of it. If a node locks up during an upgrade (happened to me multiple times), you are going to have to physically be present and either push the button on the back of the node or worth case yank power cables.
