What’s going on in Allen, Texas April 15 ?

So what do you think is happening this week on April 15 in Allen, Texas ?
As a reminder for people like me , who have a limited understanding in geography without a GPS, Allen is a city  in Collin County  Texas , United States and a northern suburb of Dallas. As of the 2010 census the city had a total population  of 84,246 (source Wikipedia)
So according to Marci Moon from the Dilly-O,  Jack Ingram will be in town on April15 !

Good news for the music  fans, but in fact what really matters here is that Cisco will open a new state-of-the-art data center.
And you will have the opportunity to participate  to the Live Internet Broadcast, featuring Rebecca Jacoby, Senior VP and John Manville VP IT  Network & Data Center Services

So what is this data center : Here is the official description
The state-of-the-art facility showcases Cisco’s data center products with a high-density footprint and the latest green technologies. Many Cisco data center technologies are used, including Unified Computing System, Nexus switches, MDS storage switches, Security, and more. Together, the Allen and Richardson, Texas, data centers enable Cisco to provide world-class business resiliency for critical business applications. These two facilities will run in active/active mode, meaning that even a catastrophic failure of either data center will not disrupt mission critical systems.

Cisco customer Chinese University of Hong Kong selected as finalist for the SNW Best Practices Award

Congratulations to Chinese University of Hong Kong (CUHK) which met  the stringent criteria defined by Computerworld, the Storage Networking Industry Association (SNIA), and SNW, we are proud of our customer’s achievement.


About the Chinese University of Hong Kong (CUHK)
CUHK transformed its IT infrastructure with Cisco Data Center Business Advantage Architecture.  With more than 14,300 post-graduate and undergraduate students from Hong Kong and 1,300 students from overseas and mainland China, CHUK also has more than 1,400 faculty staff and 5,100 administrative staff supported by its IT department, the Information Technology Services Centre (ITSC).

IT Infrastructure
The entire campus is connected to the University Campus Backbone Network via high-speed Gigabit Ethernet links, and connections within the campus network are via high speed 10 Gigabit or Gigabit Ethernet links.  Students have 24/7 access to computers in the ITSC, and some faculties and departments also provide students with their own personal computers.

CH Cheng, associate director of ITSC and head of the Infrastructure Division explains, “Our users have high expectations of the data center infrastructure. They want faster and more flexible provisioning as well as lower cost.”

Dr Paul Mockapetris likes Location/ID Separation Protocol (LISP)

You probably  start by now  to digest our March 30th Data Center Fabric launch , which was pretty rich in terms of announcements.
We still have several  topics to cover more in details . One of them is certainly LISP and I am relying on our team , led by our Fellow Engineer Dino Farinacci to provide you very soon a detailed blog on this topic – So stay tuned –
But meanwhile, I’d like to share with you a recent video interview we did with Dr Paul Mockapetris
For those who are not familiar with LISP it’s probably a good opportunity to catch up
Paul Mockapetris  , as you certainly know it, invented DNS – So why did we interview him on LISP ?
Beyond the fact that Paul likes LISP, here is a short, but  to the point explanation – Read what Jeff has to say about DNS and LISP – start with the 3 first paragraphs of his blog “FryGuys’s blog”

Still not fully  convinced about the importance of LISP ?
I like what  the “Virtual Geek” blogger Chad Sakac wrote in his report of the March 30th launch

At this point, you may wander what the difference between OTV and LISP – Read what Scott Lowe has to say in his excellent write up of the launch
“For now, it should suffice to say that OTV addresses Layer 2 connectivity between data centers while LISP helps the rest of the network more efficiently understand and adapt to the Layer 2 connectivity between data centers. Both are necessary.”

Introducing Two New UCS Bloggers

In the past week or so, I’ve introduced you to a few of my teammates, and I’m pleased that two of them have decided to share their experience and wisdom in this forum.  They bring different backgrounds and perspectives to the UCS topic, and I think you’ll enjoy the variety.

Girish Kulkarni has made guest appearances in some of my blogs to talk about our benchmark records. Soon you’ll be hearing a lot more from him about how UCS supports major application workloads of all types. He’s spent time with a number of major industry players (Tandem/Compaq/HP, Siemens, and more), heavily focused on building out integrated solutions with application partners such as Oracle, Microsoft and SAP.

Tim Stack made his blog debut yesterday, and will be talking more in coming weeks about our new platforms, their capabilities, and opportunities for RISC migration and other forms of architectural evolution. Tim has over 20 years experience in product marketing and engineering across both the server and semiconductor capital equipment markets, with the past 10 years focused on entry and mid-range servers at Sun and IBM.

Please welcome them to the UCS blogosphere!

DCI Use Case: Capacity Expansion


Today I want to bring up DCI use case that I’ve been thinking about: capacity expansion.  As you know, the purpose of DCI is to connect two or more Data Centers together so that they share resources and deliver services.  The capacity expansion use case is when you have temporary traffic bursts, cloud bursts, either planned or unplanned, maintenance windows, migrations or really any temporary service event that requires additional service capacity.

To start addressing the challenge of meeting these planned and unplanned cloud burst and capacity expansion requirements, check out the new ACE + OTV feature called Dynamic Workload Scaling announced recently.
