Emerson Network Power has reduced its data centre power consumption by more than 50% and floor space by about 75% after moving IT operations to its new global data centre at the company’s corporate HQ in St. Louis. It has closed data centres in Chicago and Cincinnati and will shortly close a legacy data centre on the HQ site.
The facility also has a 7,800-square-foot rooftop solar array which produced an average of 11,400 kVAh per month during the first year, enough energy to power nine average homes for a year, saving the emissions from 20 cars.
Worth a mention because, as the name suggests, Emerson Network Power is a major global player in supplying power and business continuity, particularly to ICT companies for telecommunications networks and data centres.
What’s new is that there is now increasing focus on where that power goes, which is why the company made a couple of significant acquisitions in the last couple of years:
• In 2008 it acquired Aperture, which provides software for managing the physical infrastructure and improving efficiency of data centres.
• Avocent, bought in 2009, is in a related area, supplying technology that gives better visibility into, and management of, data centre infrastructure.
The two companies have been brought together within Emerson Network Power to form a new division specifically focused on data centre infrastructure management, so it’s no surprise that the expertise has been used in the company’s own consolidated facility.
The only odd thing about this announcement is that, as far as I can see, there was no figures given for the PUE (Power Usage Effectiveness), which is the usual yardstick for data centre efficiency. The new facility may use a lot less power than the previous disparate sites, but how energy efficient is it?
