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.

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 »

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)

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.

This week at the Gartner Data Center Conference in Las Vegas, Cisco Services is unveiling Cisco Domain Ten(SM) – Cisco’s Framework for Simplifying Data Center and Cloud Transformation.
Cisco Domain Ten can be applied to a diverse range of data center projects – from cloud and desktop virtualization to application migration and is equally applicable whether your data center is in enterprise businesses, public sector organizations or service providers. The video here describes how we apply the Cisco Domain Ten to the private cloud use case, as one example. We’ll discuss additional use cases in future blogs and associated collateral that I’ll point you to.
Born from our extensive experience over the past years in helping customers transform their data centers, based upon the many cloud deployments – private and public, enterprise, public sector and service provider – that we’ve enabled over the past few years, we’ve formulated this comprehensive framework to help you transform your data center and guide new initiatives including cloud, virtual desktop, application migration, and data center consolidation. The Cisco Domain Ten framework covers ten key areas – domains – that – based upon our experience – are critical to consider, plan for and address as part of your data center and cloud transformational journey, and is illustrated in the diagram below. Relating this framework to other key components of Cisco’s data center strategy, you can think of the Cisco Unified Data Center as the what of the data center, whereas Cisco Domain Ten complements this by guiding you on the how (to transform).
