Are We Approaching 1.2 Jigawatts in the Data Center?

June 15, 2011 at 10:00 am PST

What are typical power and cooling densities in a Data Center these days?  What do you think they’ll be in the future?

I routinely host Data Center tours at Cisco’s headquarters.  During those walkthroughs I often discuss how the densities in our server environments have increased over time.  Facilities with 50 to 60 watts per square foot gave way to those of 100 to 120 watts per square foot, which in turn gave way to those of 175 to 200 watts per square foot.

“I’m your density.  I mean… your destiny.”

Virtual Forum for Education Leaders – Creating Community

In Welcome to the Education Blog, Gary Serda said that:

Cisco’s approach to education is comprehensive and multi-faceted. We have groups across all of Cisco that are actively engaging with Education leaders to improve education everywhere. At the core of these engagements, is our fundamental belief that the network can serve as a platform for education innovation that can dramatically improve educational outcomes for students.

One of the ways we showcase innovative and practical solutions for today’s education challenges is the Cisco Virtual Forum for Education Leaders.  This online Forum is filled with informative presentations and resources that demonstrate the success that dedicated educators are having meeting today’s education challenges.

With “virtual booths” for specific solutions and areas of IT concern, Cisco representatives available for live chats, both recorded and live presentations, and expert-led discussions--the forum provided and provides a good source of technology and solution information for Education customers. That’s right, provides. The Forum is more than a transient event: visitors are welcomed back as often as they like to get updated information about Cisco’s solutions and efforts in the Education space. A great example is this interview added last week:

Place Your Data Center Bets

June 8, 2011 at 10:00 am PST

Novelty bets are all the rage these days in gambling.  Bookmakers are laying odds and allowing side bets on the minutiae of major events ranging from athletic contests to national elections to royal weddings.  My favorite novelty bet from the 2011 Super Bowl:  how long would Christina Aguilera hold the note “brave” at the end of the National Anthem?  (It went nine seconds by my unofficial count.  Feel free to time it yourself.)

Can we get the Data Center industry a piece of this action?  Imagine the odds line for happenings in and around your server environment in the next six months: Read More »

The Role of Layer 4-7 Services in Scaling Applications for the Cloud-Computing Data Center

The Cloud Challenge
Cloud computing is increasing demands on applications and the application-delivery infrastructure must change to meet the challenge. Virtualization does not solve the problems with applications scaling, in fact it adds complexity. Infrastructure alone does not solve the challenge either. You don’t want to oversubscribe or just add capacity on demand. The infrastructure needs to respond to user demand based on business value and maintain a favorable cost structure. This means that you need intelligent load processing to manage scale, especially given the evolution of applications, which now make numerous backend function calls, which create more traffic than at the front end.

The Need for Scale
Cloud-computing applications are characterized by stateful access, with differentiated service levels, charged to the end user using the pay-per-use pricing model. Implicit in this model is the assumption that a cloud application is always on. Scaling the cloud delivery model to an Internet scale (millions of users) is a challenge that next-generation Layer 4–7 infrastructure needs to overcome.

Scaling a cloud application involves scaling three mechanisms: location (mobility), replication, and load balancing. Virtualization was an early catalyst for cloud computing because it substantially lowered the cost of replication and mobility of a prepackaged application. It does not, however, solve the load-balancing problem. Load balancing involves scaling the address, name space, transport, session, identity, and business logic of the application. Clustering enables scaling of application business logic but leaves the rest of the problem to a proxy infrastructure.
