So here is a new thing I'm playing around with.
The ability to keep track of a "rack" in a datacenter/closet etc. So far its pretty basic. It has the ability to track a name, the size of the rack and the utilization of that rack.
Devices within ONA can be linked to what set of "units" or "U" they consume in the rack. If there are things like patch panels or PDUs etc that do not have a host in ONA they can still be tracked. You can indicate if it was installed from the front or the back of the rack and if it has a depth of 1/4, half, 3/4, or full.
Anyway, just something I'm playing around with. The graphical representation of the rack is pretty well there but I have no edit ability and I need to display a bit more useful info about each rack unit.
It has also been suggested that having ONA conform in some way to TIA/EIA 606A would be a good thing. I agree but have not spent time thinking on how to conform to those standards but I see it is within the realm of possibility and that this is a small portion of that whole mess of things.
Here is a screen shot as well. Let me know what you think!
