Cisco Blog > Data Center

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.

Cisco UCS : When Opportunity Knocks

If you are managing an Itanium or SPARC based server architecture, you may be experiencing increasing maintenance costs, scarcity of administration resources, shrinking ISV support and unclear roadmaps from vendors like HP and Oracle/Sun.  You may not have thought there was a viable alternative, but imagine if you could unite computing, networking, and storage access resources with a management system designed to deliver the flexibility and agility needed to scale business operations.  

Cisco’s Unified Computing System was designed for the modern data center and has just expanded to include a portfolio of two-socket and four-socket blade and rack-optimized servers based on the new Intel® Xeon® processor E7 family. Check out the nine new world record performance benchmarks here. One of the new offerings is a two-socket Cisco UCS C260 server which can support up to 20 cores,  1 TB of memory and 16 SFF disk drives in a dense, 2U form factor. This is big-time compute, memory, and storage capability in an extremely small footprint. Up to 50 GB of memory per core for demanding enterprise applications, such as large-data-set and transaction-intensive databases, enterprise resource planning (ERP) applications, and decision-support systems.

Spring Cleaning Time? UCS Refresh For A Faster, Denser DC

About six months ago I introduced you to another one of my colleagues, Scott Ciccone, as we launched the very dense UCS B230 two-socket blade. And now, with Intel’s spring release of their next-generation Xeon E7 processors, we’ve announced updates to that original B230 platform as well as our 4-socket platforms. In addition, we’ve got a new rack-mount-flavored take on the B230 density story…
