Raritan IT team recently decided to change our naming and association schemes in Power IQ. This change reflects the new level of power usage details IT wants to track, and how we plan to utilize such information to measure energy savings from the investment in replacing old servers with new, more energy efficient IT equipment.
In the prior Power IQ naming scheme, we name the PX outlets by “phase-circuit-rack-L/R”. From this naming scheme, one can easily tell that it was PX-centric thinking. Using Power IQ, IT was able to easily know the total data center power consumption, as well as power usage by circuit and by the rack. The power consumption by individual IT devices was interesting but not as important for power capacity planning, especially when the servers were largely 1U/3U rack-mount servers.
