OK, so maybe you don't get excited about uninterruptible power supplies (UPSes) like I do. But you should definitely consider the implications of a new one from power management company Eaton, because it will let you measure energy consumption down to specific outlets. That's a pretty unique feature.
The 5PX UPS, intended for small to midsize data centers, comes with an LCD display that provides a view to the individual power draw of the devices connected to the UPS. If you use the hardware in conjunction with Eaton's Intelligent Power Suite, you can create a configuration that will use 5PX to monitor when connected servers are reaching their maximum capacity and then trigger them either to relocate the server load or gracefully shut down.
The series starts at $475 for models ranging from 1,000 VA to 3,000 VA. There is a three-year warranty on the equipment, along with technology that increases the battery service life by up to 50 percent.
