Cisco Validated Designs for Cloud -Part 4-Virtualized Multiservice Data Center 3.0

Over the past weeks, Tom Nallen introduced the concept and benefits of the Cisco Validated Design , then Laszlo Bojtos,  illustrated this concept with the Cloud Service Assurance for Virtualized Multi-Services Data Center 2.2 Cisco Validated Design, with a specific emphasis on the integration with Cisco Intelligent Automation for Cloud . Finally John Kennedy shared with us the latest news on Flexpod.

jotungThis week , I met Johnny Tung, Systems Marketing Manager for Data Center Solutions, to talk about a very interesting announcement : The Virtualized Multiservice Data Center

” Johnny , can you tell us what Happened to Cisco’s Unified Data Center on Dec 3th?

Well…it just got more interesting! You may have heard of Virtualized Multiservice Data Center. Let me remind you. It is Cisco’s reference architecture for the Unified Data Center. The big news here is that we have just released the 3.0 design. We are introducing Cisco FabricPath into the Unified Data Center network in order to simplify and scale Cloud Ready Infrastructure designs for Private and Virtual Private Cloud deployments.

VMDC

FabricPath simplifies and expands existing data center network design by removing the complexities of Spanning Tree Protocol (STP), and thus enabling more extensive, flexible, and scalable Layer 2 designs. This release marks the introduction of FabricPath-based designs into VMDC;  further FabricPath-related VMDC releases will follow as Cisco develops and evolves its FabricPath offerings.

 What does it mean for our customers ?

Cisco Domain Ten: Domain 2: Virtualization and Abstraction

Last week I introduced our new Cisco Services framework to help guide your data center and cloud transformation – Cisco Domain Ten (SM). I also described the types of challenges you should be thinking about in the Facilities and Infrastructure layer, Domain 1.  Now let’s discuss the type of challenges that Domain 2, Virtualization and Abstraction, could present to you.  While Cisco Domain Ten can be applied to help you in any data center transformation, I’ll keep focused on showing you how Cisco Domain Ten helps illuminate your path to cloud transformation.

2012 Year In Review

Two things I greatly enjoy about working in and around Data Centers are that so many different technologies converge within them and that those technologies are constantly evolving.  There’s always something new to explore.

It’s no surprise then that Data Center Deconstructed ping-ponged among several topics in 2012, from choosing a site to relocating servers to incorporating alternative energy, and more.  I even tried my hand at blogging in real-time, posting live from the annual Technology Convergence Conference.

Here’s are the Data Center Deconstructed topics that received the most attention this year.  Check out any you’ve missed: Read More »

Blink: You’re Too Slow

When playing in the high speed switching game – timing is everything.  Timing ‘sets the pace’ for visibility to established the ‘where and when,’ correlation across a broad computing environment plus compliance and digital forensics with precision time stamps.  Every element of the data center requires accurate timing at a level that leaves no room for error.

Speed is the other, more celebrated, if not obvious requirement, for the high speed switching game.  Speed that is measured in increments requiring some new additions to my vocabulary.

When looking at the ways in which we measure speed and regulate time throughout the network, I was of course familiar with NTP or Network Time Protocol.   NTP provides millisecond timing…which, crazy enough…is WAY TOO SLOW for this high speed market.   Now being from the South, I may blink a little slower than other people but I read that the average time it takes to blink an eye…is 300 to 400 milliseconds!  A millisecond is a thousandth of a second.  That is considered slow?

Turns out ‘micro-second’ level detail is our next consideration.  A microsecond is equal to one millionth (10−6 or 1/1,000,000) of a second. One microsecond is to one second as one second is to 11.54 days. To keep our blinking example alive: 350,000 microseconds.  Still too slow.

Next unit of measure?  The Nanosecond. A nanosecond is one billionth of a second.  One nanosecond is to one second as one second is to 31.7 years.  Time to blink is just silly at this point.

At one point in time I used to think higher speeds were attainable with higher degrees of bandwidth.  This may be why the idea of ‘low latency’ seems so counter-intuitive. As you hopefully understand at this point, there are limitations to how fast data can move and that real gains in this area can only be achieved through gains in efficiency – in other words, the elimination (as much as possible) of latency.

For ethernet, speed really is about latency.  Ethernet switch latency is defined as the time it takes for a switch to forward a packet from its ingress port to its egress port. The lower the latency, the faster the device can transmit packets to its final destination.  Also important within this ‘need for speed’ is avoiding packet loss. The magic is in within the balancing act: speed and accuracy that challenge our understanding of traditional physics.

Cisco’s latest entrant to the world of high speed trading brings us the Nexus 3548.  A slim 48 port line rate switch with latency as low as 190 nanoseconds. It includes a Warp switch port analyzer (SPAN) feature that facilitates the efficient delivery of stock market data to financial trading servers in as littles as 50 nanoseconds and multiple other tweaks we uncover in this 1 hour deep dive into the fastest switch on the market. The first new member of the 2nd generation Nexus 3000 family.   (We featured the first generation Nexus 3000 series in April 2011)

This is a great show – it moves fast!

Segment Outline:

  •  – Robb & Jimmy Ray with Keys to the Show
  •  – Berna Devrim introduces us to Cisco Algo Boost and the Nexus 3548
  •  – Will Ochandarena gives us a hardware show and tell
  •  – Jacob Rapp walks us through a few live simulations
  •  – Chih-Tsung, ASIC designer walks us through the custom silicon

Cisco Domain Ten: Domain 1: Facilities and Infrastructure

Yesterday I introduced you to the Cisco Domain TenSM, Cisco Services’ framework for simplifying data center transformation.  This model is applicable to both business  (enterprise), public sector (e.g. government, federal) and service provider (incl telco) organizations.

Today I will summarize some key challenges that you should consider when planning a transition to cloud (as one example of data center transformation), for Domain #1 – Facilities and Infrastructure.
