As an HPC old-timer, I’m used to thinking of HPC networks as large layer-2 (L2) subnets. All HPC traffic (e.g., MPI traffic) is therefore designed to stay within a single L2 subnet.
The next layer up — L3 — is the “networking” layer in the OSI network model; it adds more abstractions than are available in L2. For example, IP switching and routing occurs at L3. Indeed, L3-based networks can be comprised of multiple subnets.
I’ve come to appreciate that, especially with modern high-speed networking gear, there is no reason for limiting HPC networks to L2.

In his paper “A Data Center Fabric is Critical to the Next Generation of Data Center ” published on January 2014, Zeus Kerravala (@Zeeman) wrote ” The data center has gone through many major evolutionary changes over the past several decades, and each change has been defined by major shifts in architectures…in 2011, another major shift began: the shift to a virtual data center. This has been the primary driver in enabling customers to transition to the cloud and ultimately IT as a service…Next-generation data centers will see a greater coupling of hardware and software to bring together both physical and virtual infrastructure. The result will be a fluid, dynamic “fabric” capable of moving IT resources where the business needs them.”
End of January at Cisco Live Europe, Cisco introduced new solutions “Data Center and Cloud Networking Accelerations Continues” expanding the portfolio of data center fabric solutions designed to create this virtual data center.
On March 11, a panel of experts shared the best ways to achieve this shift . You can access here to the recording
Data Center Network Evolution. Why Now
Join a panel of experts
for a special 45 mn conversation
During this webcast, our guests examined solutions to address the need for elimination, integration and consolidation. Eliminating IT silos will allow your resources to be ready when and where they’re needed, and can be achieved by implementing a data center fabric. With the capability of being quickly and easily built—and rebuilt—as necessary, data center fabrics provide an overarching, unified infrastructure to securely house your data and allow for benefits such as:
- Consolidation and simplification of the network, compute, storage, and application resources
- Faster delivery of services
- Enhanced utilization of resources
- More productive IT staff and employees
- Lower operating expenses
So to be ready to shift into high gear and accelerate , register now to discover the optimal way for a smooth transition.

We are looking forward to an exciting 2014 where many are predicting this is the year of the Internet of Everything. We foresee this trend affecting the banking industry as well.
As most consumers get connected using their latest version of a smartphone, mobile tablet, or gaming system, these technologies are changing how consumers interact in every aspect of their lives. For example, consumers are getting more accustomed to instant, intimate video conversations with friends and family from their homes, so the next logical step is to add these features outside the home.
Many banks are looking into using video conversations to engage more effectively with customers. UMB Bank, a retail bank based in Kansas City, has transformed how they interact with customers by using Cisco’s video conferencing solution and Syngrafii’s LongPen Solution that resulted in 500 transactions conducted via video with a virtual banker…saving nearly 150 hours for bank personnel.
These time savings grew wallet-share by enabling UMB to meet with and call an additional 1,000 customers and helped the branches increase revenue by nearly 50 percent.

First off, we’d like to thank everyone for their continued use of our projects and products here at Sourcefire, now a part of Cisco. We love making great software, and we love for you to use it and contribute back. It’s been a great transition so far into the Cisco community, and recently, we held an Open Source Community Meeting at RSA, and we’d like to provide the content out to our Open Source user base as well.
The best way for us to do this is through a Webinar where we can present the current state of our projects, the future of the projects, how the projects are continuing to move forward inside of Cisco and of course, make ourselves available for Questions and Answers.
We are planning to hold the Webinar
Thursday, March 13, 2014
12:00 PM EST
for the webinar. We look forward to seeing you and hearing from you then!
In my role as Cisco’s Chief Futurist, I get many questions about what the future holds and how new technology and emerging solutions will change our lives. Given the positive feedback and the volume of questions being submitted from the community around the first series, I’ve decided to do another series to answer questions from the education and tech community around the Internet of Everything (IoE). Whether the questions are global in scope, such as how the Internet of Everything will shape our world, or small in nature, like today’s Ask the #IoE Futurist question about batteries, I enjoy the challenge of answering them all.
It’s true what most school teachers say, “There is no such thing as a bad question.”
In fact, when it comes to questioning what the future of technology looks like, the ideas from Malcolm Gladwell’s famous book, The Tipping Point, come to life.
Gladwell states that a tipping point is when a small idea, technology or trend crosses a threshold and “spreads like wildfire.” Today, we are witnessing a tipping point in technology innovation that is representative of small innovations that have a compounding effect on society. Microscopic sensors, tiny wearable mobile devices, miniscule packets of energy, and even an AA battery have the potential to impact future innovation and what it means to be connected.
In this post, I’ll answer a question from Chad, a student of Cisco Champion Karen Woodard, about how specifically new developments in battery technology could impact new solutions. Here is Chad’s question:
Question: “Will the future of battery technology prohibit the advancement of computers or technology in general?”
