Algo Boost Series: Part 1 Nexus 3548 Latency Innovations

The Nexus 3548 with Algo Boost was announced last week and received a lot of positive buzz around this game changing innovation. To follow up on Berna Devrim’s Introduction Blog, I am introducing a multipart series that goes into more specifics by Cisco experts. As part 1 of the series, I recently had the opportunity to have a chat with Will Ochandarena about the latency enhancements. Will is a Senior Product Manager in the Server Access and Virtualization Business Unit.  In this role, he is responsible for the Nexus 3548 switch, and Cisco’s low latency switching strategy.

GD: The Cisco Nexus 3548 switch with Algo Boost was announced on September 19th and received a lot of positive attention. Can you elaborate a little more on the latency that this switch can achieve? How does this benefit our financial customers?

<WO>: The custom switching ASIC in the Nexus 3548, codenamed Monticello, sets a new bar for switching latency.  Our engineers worked tirelessly to eliminate unnecessary nanoseconds from the forwarding path, tweaking it down to as low as 190 nanoseconds (ns).  Best of all,  this latency is achieved even when we are doing full layer-2 and layer-3 switching, with features such as Network Address Translation (NAT) enabled.   We actually went as far as to offer a few different switching modes, each with different latency and forwarding characteristics, in order to give our customers the most flexibility in their deployments.

In terms of the impact on our end customers, we consistently hear from companies in the financial community that switch latency has a direct impact on the profitability of their business. Trading firms -- as well as the exchanges and other participants -- gain significant business advantage if the supporting infrastructure enables them to acquire data and execute trades nanoseconds faster than the competition.

Introducing Cisco Algo Boost and Nexus 3548 – Breaking 200 ns Latency Barrier!

… While Delivering Superior Fabric Visibility!

Today, at the High Performance Computing for Wall Street event, we announced Cisco Algorithm Boost or Algo Boost technology, a groundbreaking networking innovation with numerous patents pending, that offers the highest speed, visibility and monitoring capabilities in the networking industry.  A true game changer delivering competitive advantage to our customers!

Ideal for high performance trading, big data and high performance computing environments, this new technology offers network access performance as low as 190 nanoseconds, more than 60% faster than other full featured Ethernet switches.  When your business success is determined by nanoseconds, this is a huge gain!

The first switch to integrate the Cisco Algo Boost technology is the new Cisco Nexus 3548 full-featured switch which extends Cisco’s leadership in networking by pairing performance and low latency with innovations in visibility, automation, and time synchronization.  And it is tightly integrated with the rich feature set of our Nexus Operating System, a proven operating system used in many of the world’s leading data centers, creating a truly differentiated offering.

USS Cisco Captain’s Log on Networking Tech Field Day 2

Captain’s log, October 27, 2011:

The USS Cisco took off for the Gestalt IT Networking Tech Field Day 2 with Captain Omar Sultan (see picture below, courtesy of techfieldday.com), Data Center Solutions Sr. Marketing Manager, at the helm. Tech Field Day networking industry experts gathered on the bridge, cleverly disguised as the Cisco Cloud Innovation Center (CICC) Lab, for an informal, no-holds-barred conversation on recent Nexus portfolio announcements, the continued march towards automated provisioning of cloud services and ever-evolving VM networking technologies.

For those who weren’t at the event or haven’t seen the video recording yet, please excuse my unabashed geekiness, but you’ll have to watch the first minute of the video to get the above reference. As a new member of the Data Center Solutions Marketing team, this is also my first foray into the Cisco blog-o-sphere, so I hope to share some fresh viewpoints on the day’s events.

Several things were made very apparent during the Tech Field Day session:

Re-defining Fabric Scale: Thinking Beyond the “Box”

Today we are making a significant announcement with several new innovations across our data center and switching portfolio that showcase how our customers can build large scale-up and scale-out data center networks.  While the press release does a great job (thanks Lee!) of highlighting all the innovations across the Nexus Unified Fabric portfolio and the new ASA 1000v, two aspects of the announcement stand out quite prominently:

  1. Cisco is delivering the highest density 10GbE modular switching platform in the industry
  2. Cisco is delivering the most scalable fabric in the industry and, by extension -- on the planet! (we’re told planet sounds much cooler)

No. 1 above is fairly straightforward. With our new 2nd-generation F2 line card and Fabric 2 module, at 768 ports of 10GbE line-rate switching ports running NX-OS, the flagship Nexus 7018 in a fully-loaded configuration is simply the epitome of switch scale.

No.2 is where things get interesting, because we’re no longer thinking about just the “box” but rather, how we can weave different elements across the data center into a holistic “fabric”.  This systems-based approach focuses on multi-dimensional scale transcending the box and even the data center LAN, to span between data centers, while providing feature-rich fabric capabilities.  At 12,000+ 10GbE nodes supported as part of one Fabricpath-enabled system, and with the ability to support Fabric Extender (FEX) technology (plus L2 and L3 capabilities), this approach re-defines fabric scalability at 2X the scale and half the cost point of the next best claim in the industry. More important, it achieves this in an evolutionary manner for our 19,000+ NX-OS customers, offering investment protection for brownfield deployments while raising the bar for greenfield environments!

The Nexus platforms have been around for 3+ years, and over 500 customers have deployed FabricPath on the Nexus 7000 alone since its introduction about an year ago. It is a proven technology. With Fabricpath now coming onto the Nexus 5500 platforms, the momentum is likely to spike up with a mix of both size and scale. Like I said, things get interesting.

To make it more fun, our technical experts from the product teams have taken a data-driven approach and compared Cisco’s new innovations and our box and system-scale with others in the industry.

They looked at a couple of representative examples -- the first being, what it would take any other vendor to build a non-blocking 768-port 10GbE “switch”, with capabilities similar to what the Nexus 7000 could provide in a single chassis. The second example takes a look at what it takes to build a “fabric” with Cisco leveraging its Nexus portfolio and NX-OS to build that.

Take a look and let us know what you think. It is useful to note that most vendors in the industry today have no fabric capabilities to speak of, and the few that are attempting a systems approach, have really limited to no customer traction thus far. Our customers and key analysts tell us that Cisco has a multi-year innovation lead in this space, even as Cisco continues to focus on bringing the network, compute, storage and application services together with integrated management to drive productivity and efficiency across traditional IT and organizational silos.

Big Compute, Big Data, Big VMworld 2011 session

This is a review post for the Big Compute and Big Data, NoSQL session. Hmm, when signing up for the session I was concerned about being a little lost on the topic, but the panel was very good.
