TU Darmstadt Rolls Out Cisco Unified Access to Prepare for 802.11ac

May 27, 2014 at 11:31 am PST

Technische Universität Darmstadt, usually known as TU Darmstadt is a research university based in Germany. It was founded in 1877 and over the last 137 years has grown to be among the largest and most prestigious public universities in Germany serving over 25,000 students per year. It is the alma-mater to many world-wide leaders from Nobel prize winners, a CEO of a fortune 500 company, a president of a country and multiple World Robocup champions.

No wonder, they have a reference from Albert Einstein!

In 2009 TU Darmstadt embraced BYOD with the 5508 Series Controller managing the 1140 802.11n Access Points. Recently we talked to Thomas Vogel, the Head of Network Group and Andreas Liebe, the Network Services Manager who have over 15 years of experience managing WLAN environments. In this blog, we will describe some of the details of WLAN deployments using the 3850 Series Switch and the 5760 Series Wireless LAN Controller to address the new requirements in the school environment.

How FCoE Helps Cisco Reduce Data Center Infrastructure

What a difference a networking cable can make in a data center’s infrastructure requirements and costs…especially when that cable uses Fiber Channel over Ethernet (FCoE) technology. An industry-standard, FCoE carries Fibre Channel over Ethernet links, which reduces the number of I/O adapters, cables, and switches in the data center.

If You Want incredible Collaboration Experiences, IT Services Can Deliver

May 20, 2014 at 8:03 am PST

I must be in the right business. I’m a pretty easy-going guy, but one thing that gets me worked up is inefficiency. Lines at the store, info I need to enter again and again online, meetings that exist just to schedule another meeting…arrrgh. That’s why I am so excited by the direction coming from Cisco’s Collaboration Technology Group. Simplifying work experiences. Removing clutter from the desk. Reinventing how we innovate and engage across corporate and physical office boundaries. That’s just what the DX80 desktop collaboration device, announced here at Cisco Live, is designed to do. Give me a DX80 bumper sticker, and I’ll put it on the back of my rental car right now (Sorry, Hertz).

I am not alone in my love of efficiency. In this age of “Pace of Change2,” the top of mind for every business leader is how to get more done faster. According to a recent CIO Insights Study, innovation, efficiency, and cost reduction are CIOs’ top business priorities, in that order (Cisco Strategic Marketing Organization, Nov. 2013). Collaboration holds the promise of greatly increasing productivity for organizations of all sizes, in every industry.

Technology-enhanced collaboration is more than a technical architecture or product. What do you think would happen if you put a DX80 on every worker’s desktop at your company? Without network optimization, training, and adoption services, there might not be much change in productivity. And how would you measure success?  Putting devices on a desk and making sure they are functional is not an effective measure of success.  Are they being used?  Is video being turned on every time?  Is it changing the way people work?  You need to measure whether use of the devices is resulting in the benefits you expected to see. And you’ll want to adjust your strategy and support structure based on what you’ve learned. Read More »

How IT Leaders Can Embrace the Change that Comes with Network Programmability

The programming of network resources is not just a trend, but also a way to future-proof IT and business needs. This blog series examines how infrastructure programmability is providing a faster time to competitive advantage and highlights the differences between programmable infrastructure and traditional infrastructure, and what programmability means for your entire IT infrastructure.

To read the first post in this series that defines infrastructure programmability, click here.

To read the second post in this series that discusses benefits of network programmability, click here.

According to a recent Network Computing article, changes in network virtualization (overlaying virtual networks over a physical infrastructure) and network programmability (provisioning and controlling its behavior) are causing some to wonder what’s in store for the networking profession.

These changes mean that our skill sets will evolve and our jobs will get more interesting. As the need to build more agility into IT systems becomes more urgent, we are looking for ways to reduce complexity, drive simplification and reduce costs to invest in new initiatives that are critical to the business. We must free up resources so that IT can build new capabilities and provide faster time to new business competitiveness. How can we do this? A new model for IT – one that is simple, smart and secure.

 The programming of network resources is not just a trend, but also a way to future-proof IT and business needs.  View Executive Perspectives.

How Cisco IT Solved Its Internal Cloud Dilemma

May 7, 2014 at 4:30 pm PST

Is your organization looking to build a cloud?

You’ll want to learn how Cisco’s John Manville leveraged an internal, private, infrastructure-as-a-service cloud to drive business value.

View John Manville's Cloud Insights Video Podcast

View John Manville’s Cloud Insights Video Podcast

John Manville is responsible for Cisco’s Global IT infrastructure  - which includes the data centers,  networks, platforms and more. Overall, John’s role is to implement Fast IT, which is really about being adaptable and responsive to business needs.

What technology helps drive this responsiveness and adaptability? “There are many solutions that can help, but if I had to sum it up in one word, that word is  cloud” replied John .

Cisco uses internal cloud technology for several important business imperatives. Through the cloud, we are  balancing internal IT workloads and providing our engineering team the tools needed for OS development. We are also using the internal cloud for external capabilities. For example, Cisco Smart Services uses our internal cloud to offer services to external customers.

Recently, John had the chance to participate in a new Cloud Insights Video Podcast to discuss the challenges his team faced prior to cloud implementation. Like most IT teams, they were challenged by speed of delivery of business capabilities, driving Total Cost of Ownership (TCO)  down and completing maintenance on the underlying infrastructure with minimal impact on the business users or applications they need on a daily basis.

To offset these challenges, his team  developed and deployed CITEIS (Cisco IT Elastic Infrastructure Services), an internal, private, infrastructure-as-a-service cloud. CITEIS started off as a way to provision virtual machines, but the team quickly realized that it  wasn’t enough so they  added on more middleware and database capabilities . Now, it’s a rich service that John’s team  offers to their clients.
