Basic Power Distribution Unit Information

A power distribution unit (PDU) is any device that allows you to remotely toggle power to your equipment. Once you install it, you won't have to drive out to a remote facility to turn something on/off or reboot it.

You may have an outlet switch at home with a handheld remote. That kind of device is, in essence, the world's simplest power distribution unit. In corporate, government, or industrial settings, they're much more capable.

First is the device itself. A quality PDU will be built with a metal chassis and mounted in (or on the side of) your server rack. It will have a quality web interface for configuration and direct control.

Next is communication. A handheld remote makes no sense in a business/government environment. You'll want some kind of protocol communication, usually an open standard like SNMP or DNP3.

Finally, you need to think about capacity. How many amps do your remote devices each consume? What power rating do your power-distribution-unit relays need to handle?
