When it comes to data centers, I like to keep a clean shop. You might say that I’m a tad anal about cabling, labeling, and general organization. It’s a real nightmare to sift through a spaghetti mess of cables when you’re trying to solve a problem.
Anyhow, here’s a glimpse of the back of a newly installed rack with 21 servers in it.
All cables are labeled on each end and neatly bound with Velcro straps. The labels are laser printed and identify what it’s connected to as well as the far end. The power cables are 1ft and 2ft, respectively for each of the two power supplies in each server. No excess means no mess. I know what you’re thinking - I bet that cables a mess inside that cable tray. Nope, neat and tidy - even in the places you can’t see it!
The cabinet is an HP 10000 G2 server cabinet. It has extra wide channels on each side for cable management and is extra deep with split-back doors. We use the HP 17.3 kVA PDU (power distribution unit) mounted in a zero-U configuration. It provides 72 plugs with two 30amp 3-phase 208v circuits per cabinet. It’s a monster, but allows us to use every inch of the server cabinet.
Here’s the front:
