After countless brainstorming sessions, code reviews, lab trials, scores of NDAs and nearly two years of intense speculation from media, analysts and the internet community -it is finally here! Today, Cisco is pulling back the curtains to reveal details of the vision ofApplication Centric Infrastructure (ACI)announced in June 2013. With shipping products as part of the announcement today, Cisco is also taking the first steps in making this vision a concrete reality. In the process, Insieme networks also returns to become a wholly owned subsidiary of Cisco.

For those tuning into the press conference and webcast today , you will see John Chambers, Rob Lloyd and Insieme executives get into the specifics of ACI, with the event being hosted out of the historical Waldorf Astoria in New York.  You will also see Cisco's partners and customers share both the stage as well as a common vision.

So, after months of silence, there will be quite a bit of information sharing, perhaps Information overload even. This is an announcement with innovation at multiple levels, and even for the tech savvy it will take time to fully understand and appreciate the architecture and the benefits it brings.

I wanted to share a few key concepts, innovations, and highlights of the announcement today. We will delve into additional details and dissect these pieces over the next few weeks on this blogging platform as well the publicwww.cisco.com/go/aciwebsite,which will host a lot of the structured content.

1. The concept of Application Centric Infrastructure

We put together a short video to distill the concepts of ACI. It encompasses a lot of what existing networks today, as well as emerging SDN concepts (regardless of what the definition of SDN is), and goes quite beyond what anyone else is offering out there today. You will see some critical differentiators here:

• De-coupling of application and policy from IP infrastructure
• Ability to define application network profiles and apply them
• Integration of physical and  virtual infrastructure elements with end-to-end visibility
• Openness at a all levels
• Scale, with security

2. Application Policy Infrastructure Controller (APIC)

The Application Policy Infrastructure Controller (APIC) is a new appliance that will be the heart of the ACI fabric.  While the actual product will ship around Q2 of next calendar year. An APIC simulator will also be made available on a controlled basis for customers and partners to get familiar and additional information will continue to be made available. Unlike most software-only controllers in the market today that have little ability to exploit the capabilities of hardware, APIC provides a holistic system level view and an ability to tap into the capabilities of the underlying infrastructure. While it will initially be paired with the Nexus 9000, the APIC will be expanded to support other parts of the portfolio as well as other infrastructure building blocks.

The APIC utilizes a centralized policy-model with an application network profile and open architecture that allows for the application needs to be defined and mapped to infrastructure, to make it application-aware.

3. Nexus 9000 -Expanding the Nexus switching family

We're expanding the highly successful Nexus family with the next "big bad boy"  -the Nexus 9000.  This will initially come in two models -the Nexus 9500 and the Nexus 9300, with the former shipping now. It has a variety of innovations for all of the "5 Ps" -(i) an extremely attractivePricepoint , optimized for 1G to 1/10G in the access, and for 10G to 40G migration in the aggregation layer. In addition (ii) It brings in Industry leadingPerformancewith 1.92Tbps per line card and is 100G ready. (iii) Has significantly higher non-blockingPort-density(iv) Flexibleprogrammabilitywith JSON/XML API with a Linux container for customer apps and (v)Power efficiency-with an innovative design that has no mid-plane/backplane resulting in 15% greater power and cooling efficiency.

The Nexus 9000 is designed from ground-up to be ACI ready with a combination of merchant silicon and Cisco custom ASICs to deliver the"5 Ps".

In addition to the Nexus 9000, keep a look out for the Application Virtual Switch (AVS).

4. 40G BiDi Optics*

As customers migrate to 10/40G over the next few years, the cost of laying new fiber and overhauling the optics is a tremendous drag and raises barriers for 40G adoption. I wrote about multi-layered innovations -this is one of them at a component level. The 40G BiDi lets customers preserve their existing 10G cables, resulting in tremendous time savings, cost savings (labor and fiber) as well as improved time to market for the upgrade. Bandwidth upgrades is one of the top reasons that drive network refreshes, and this innovation (a Cisco exclusive) produces remarkable results

5.  The Partner Ecosystem

It is not possible for one company to address all the challenges manifesting in the data center on its own, no matter how revolutionary the architecture is or how radical the innovations are. This is where a rich ecosystem of partners have stepped in(see the technology leaders rally here), each of them market and innovation leaders respective domains, to make the vision of ACI all the more real and consumable.

Their vision and commitment is reflective both of the shared vision and commitment to transform the data center infrastructure, as well as reflective of the open architecture of the ACI approach in general, building on the principles of the Cisco Open Network Environment (Cisco ONE), but also taking it to other aspects of the infrastructure. You may expect to see a lot of the demos  as the APIC becomes generally available next year,  even as services offerings around ACI become much richer, as evidenced by Scott's blog link below.
