rackmount managed PDUs

[brandon at rd.bbc.co.uk (Brandon Butterworth)]

I've used

http://www.audionics.co.uk/products/emu.htm

but for new installs I'm looking at 

http://web2.raritan.adxstudio.com/products/power-management/Dominion-PX/DPCR20A-32/

for the per port power consumption data, increasingly important with
UK colo power price increases

I'm not a fan of zero U devices unless you get racks they're designed
for as they get in the way of other cabling and server rails
(protruding parts seem to be common with some manufacturers rails) and
make any work risky
