May 3, 2013 at 10:00 am PST

More and more businesses these days are taking steps to reduce their carbon emissions.  (Cisco is one of them, as the company met a 25% greenhouse gas reduction goal last year and subsequently upped it to 40%.)

There are several compelling reasons for doing so – some philosophical and others pragmatic.  Here are a few:

Sniffing Out a Data Center’s PUE

April 10, 2013 at 10:30 am PST

Power Usage Effectiveness or PUE, is the most commonly used metric in Data Centers today.  Data Center industry organizations tout it, major companies brag about their scores, and energy efficiency certifications use it in their ratings.

Despite how thoroughly it has been embraced, though, it’s not without flaws.  In my opinion, they mostly stem from the fact that PUE is more complicated than it looks.  Although calculating the metric is a relatively straightforward exercise, the resulting score doesn’t tell you anything about the factors that influenced it.  Hence why it’s a bad idea to compare PUE among Data Centers.

Light-as-a-Service: Why IT and Lighting Will Converge

After witnessing a live demo of the PoE-powered, iphone-controlled LED lights in the EnergyWise pavilion at Cisco Live, the IT manager for a well-known auto maker approached Chris Isaacson, CEO of NuLEDs. He asked one question: “How many colors does the fixture support?” Chris’s reply echoed Henry Ford’s famous quote in his 1927 autobiography, “You can have any color as long as it’s in the visible spectrum.”

The marriage of microprocessors with legacy products will create new products, solutions and markets. The work of partners in the Cisco EnergyWise pavilion at CiscoLive San Diego highlights this well. Though not all 17,000 Cisco Live attendees visited the EnergyWise Pavilion, those who did witnessed a world in transition. Read More »
