No place to put it in the rack. these are blades. But they do have 3 Cisco bricks
with their own private pathway between them so I can connect each server to a
local switch.

Too many nodes and not enough time, and I mostly manage by exception.
If it is running well I don't want to have to keep an eye on it.  We have a 
daemon that collects information on each node and keeps an eye on the 
local log file. Then we have capture the serial console into a log file.
