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.

EMC World was wonderful. It was gratifying to meet industry professionals, listen in on great presentations and watch the demos for key business enabling technologies that Cisco, EMC and others have brought to fruition. Its fascinating to see the transition of DC from cost center to a strategic business driver . The same repeated all over again at Cisco Live. More than 25000 attendees, hundreds of demos and sessions. Lot of interesting customer meetings and MDS continues to resonate. We are excited about the MDS hardware that was on the display on show floor and interesting Multiprotocol demo and a lot of interesting SAN sessions.
Outside these we recently did a webinar on how Cisco MDS 9710 is enabling High Performance DC design with customer case studies. You can listen to that here.
So let’s continue our discussion. There is no doubt when it comes to High Performance SAN switches there is no comparable to Cisco MDS 9710. Another component that is paramount to a good data center design is high availability. Massive virtualization, DC consolidation and ability to deploy more and more applications on powerful multi core CPUs has increased the risk profile within DC. These DC trends requires renewed focus on availability. MDS 9710 is leading the innovation there again. Hardware design and architecture has to guarantee high availability. At the same time, it’s not just about hardware but it’s a holistic approach with hardware, software, management and right architecture. Let me give you some just few examples of the first three pillars for high reliability and availability.
MDS 9710 is the only director in the industry that provides Hardware Redundancy on all critical components of the switch, including fabric cards. Cisco Director Switches provide not only CRC checks but ability to drop corrupted frames. Without that ability network infrastructure exposes the end devices to the corrupted frames. Having ability to drop the CRC frames and quickly isolate the failing links outside as well as inside of the director provides Data Integrity and fault resiliency. VSAN allows fault isolation, Port Channel provides smaller failure domains, DCNM provides rich feature set for higher availability and redundancy. All of these are but a subset of examples which provides high resiliency and reliability.
We are proud of the 9500 family and strong foundation for reliability and availability that we stand on. We have taken that to a completely new level with 9710. For any design within Data center high availability has to go hand in hand with consistent performance. One without the other doesn’t make sense. Right design and architecture with DC as is important as components that power the connectivity. As an example Cisco recommend customers to distribute the ISL ports of an Port Channel across multiple line cards and multiple ASICs. This spreads the failure domain such that any ASIC or even line card failures will not impact the port channel connectivity between switches and no need to reinitiate all the hosts logins. You can see white paper on Next generation Cisco MDS here. At part of writing this white paper ESG tested the Fabric Card redundancy (Page 9) in addition to other features of the platform. Remember that a chain is only as strong as its weakest link.
The most important aspect for all of this is for customer is to be educated.
Ask the right questions. Have in depth discussions to achieve higher availability and consistent performance. Most importantly selecting the right equipment, right architecture and best practices means no surprises.
We will continue our discussion for the Flexibility aspect of MDS 9710.
-We are what we repeatedly do. Excellence, then, is not an act, but a habit (Aristotle)
Data centers are undergoing a major transition to meet higher performance, scalability, and resiliency requirements with fewer resources, smaller footprint, and simplified designs. These rigorous requirements coupled with major data center trends, such as virtualization, data center consolidation and data growth, are putting a tremendous amount of strain on the existing infrastructure and adding complexity. MDS 9710 is designed to surpass these requirements without a forklift upgrade for the decade ahead.
MDS 9700 provides unprecedented
Performance - 24 Tbps Switching capacity
Reliability -- Redundancy for every critical component in the chassis including Fabric Card
Flexibility -- Speed, Protocol, DC Architecture
In addition to these unique capabilities MDS 9710 provides the rich feature set and investment protection to customers.
In this series of blogs I plan to focus on design requirements of the next generation DC with MDS 9710. We will review one aspect of the DC design requirements in each. Let us look at performance today. A lot of customers how MDS 9710 delivers highest performance today. The performance that application delivers depend
Hello again, Marc Nagao and the Cisco Small Business Team.
Over the weekend, my family and I were in Indian Wells to watch the world’s best tennis players play at the BNP Paribas Open. I have to say, watching them play live, at competition speed, is something to behold. It’s difficult to comprehend the speed, power and consistency out of these players.
Speaking of Speed and Power, recently, my brethren Product Manager, David Harper, finished up development of a new release of the Cisco FindIT Network Discovery Utility that uses the Cisco Automated Software Delivery Service to provide easy speedy access to Small Business firmware. This new service tool is simple to use, intuitive and a snap to get started. It will let you know when there’s a new firmware update and in seconds that firmware can be loaded up on your Cisco Small Business device. I even conned Dave into doing a demo for you all! But the best part, it is FREE.
Take it away Dave:
Hello Everyone, Today I want to talk about Cisco FindIT. FindIT is a web browser plugin that you can use to discover all Cisco Small Business branded devices on your network, and then you can easily view device information, click to open the administration GUI, or click to access support resources. We have just released version 1.1 of FindIT, and this version automatically notifies you about firmware updates for the devices on the network and then lets you click to download them to your PC. I’ve attached a short, five minute video below that show how FindIT works and how you can use it when you are installing a new network.
Did you watch the Academy Awards this week? It sure would been great to get my mug in Ellen’s selfie shot. I could have been Bradley right? ..and a slice of pizza would have been great with Julia, Harrison, and “Marty”. Certainly this year’s Oscars was the best one in years.
Speaking of good shows -- as Master of Ceremonies here at Cisco Small Business, I wanted to pass along some fantastic news from another brethren Product Manager, Robin Penn. Her Cisco Small Business Services and Support team has been making a good showing recently by adding 15 additional Latin American Countries where folks can purchase Cisco Small Business Service. For some time, we have received requests from partners, customers and team members to extend our Award Winning coverage to more Latin American countries. As you can imagine, many folks are quite happy about this.
But wait… what exactly did Robin do? We already sold Small Business Support Service in Argentina, Brazil, Chile, Colombia and Mexico. And now…the envelope please to see the new entrants: Belize, Bolivia, Costa Rica, Dominican Republic, Ecuador, El Salvador, Guatemala, Honduras, Jamaica, Nicaragua, Panama, Peru, Puerto Rico, Trinidad & Tobago and Venezuela. And all are winners
Customers now can purchase (through their partners) the value-priced Cisco Small Business Support Service:
Three Years of Award-Winning Technical Support
Advanced Product Replacement -either Same Day Ship or Next Business Day**
Unlimited telephone support with Cisco Certified engineers, 24 hours daily in English, business hours in other languages
Major and minor software releases
So now, in more and more countries, especially Latin America, Cisco’s Best-in-show Small Business products can be purchased with the award-winning Cisco Small Business Support Service. So as Robin would say, buy/sell the best Small Business products with the Industries’ Best Service and Support, all in the one shot.
Thanks for hanging out with the Cisco Small Business Team -- make it a good rest of the week.
