Cisco employees are moving towards a mobile collaborative office environment – within the workplace. We sit where we like and log into the nearest phone, using extension mobility. But when we traveled to different Cisco offices around the world, we couldn’t log in to the Cisco IP phone: extension mobility only worked at certain limited locations within our home region.
Now, employee phones can essentially follow them to any Cisco office worldwide because Cisco IT deployed the Extension Mobility Cross Cluster (EMCC) feature on Cisco Unified Communications Manager (Cisco UCM).

Saturday morning wasn’t complete for me as a kid if it didn’t include a bowl of pre-sweetened cereal and time watching cartoons. Challenge of the Super Friends was my favorite, thanks to its unforgettable opening sequence and the chance to see Superman, Batman and other heroes overcome the latest scheme by the Legion of Doom to take over the world.
One of the Legion’s intriguing villains was Bizarro – the imperfect duplicate of Superman with the blocky white face and backwards S on his chest.

John Stewart, Cisco Senior Vice President and Chief Security Officer, explains how Cyber Security is at the forefront of today’s “hacktivism” campaign and becoming a popular topic not only to security professionals, but CEO’s as well. John highlights the importance of “in-memory” threats and how data is no longer on software or disk while being extremely difficult to track. The evolution of Cisco IT’s BYOD strategy is of major importance when placing security throughout a multiplicity of different devices. This new initiative is something to be optimistic about while being able to get on top of the threats in today’s “Internet of Everything.”

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.
