PUE: to compare is human – to improve is divine (part 2 of the DS PUE series of articles)

This is the second part of our discussion about PUE and how I believe it should be used for those who are beginning on their journey to improve power effectiveness within their data centres. In the first part we spoke about the basics of PUE and what the metric gives you. In this part I discuss where to focus to reduce your PUE, what benefits must be derived it and when, pragmatically, you should NOT consider PUE improvement as an option.

Additionally, the gateway has an extra sensor and metric ability of using Geo-location. The on board PowaINFRA gateway has the same capabilities as the standard PowaINFRA gateway and is compatible with the sensors in the PowaINFRA range. Other vehicle tracking systems are typically wired and thus rely on the sensors to be connected to contacts on the main unit. No only is this a more difficult installation but it limits the number of sensors installed in a vehicle as it is not cost effective. Most vehicle installation of refrigerated trucks only have one temperature probe installed, either on the output or return vents of the cooling units. This is typically located at the front of the refrigeration trailer and the cooling varies within the trailer. Thus it is likely that the load can ex
