Cisco IT Datacenter Day 2015, Allen, TX – Disrupt or be disrupted!

By 2020 75 percent of all companies will be fully digital. The huge shift to a fully digital ecosystem has accelerated over the last couple of years, resulting in Fast IT, which is the new operating model for Cisco IT. The 3rd annual Data Center Day in Allen, Texas, could not have been a better showcase for this new model with its theme, “Disrupt or be Disrupted!” About 130 Cisco customers from every market segment, and in total more than 300 people, attended the Data Center Days on April 13th and 14th.

Interop 2015 : ITD is Best of Interop finalist


ITD (Intelligent Traffic Director) has been selected in Top 3 finalists in the Best of Interop 2015 Data Center category. ITD Delivers:

  • $2 Billion TAM disruptive technology: This technology innovation disrupts today’s $2 Billion TAM for load-balancers, redirection and clustering solutions
  • 100x Scale improvement: The high-end load-balancers today can handle about 200Gbps traffic. ITD can load-balance 20Tbps traffic.
  • 1000x cost-savings for customers: A 40Gbps L4 load-balancer costs about $200k to customers. ITD provides multi-Tbps load-balancing for a fraction of the price.
  • Zero Latency: ITD performs load-balancing, redirection, NAT and access control, all in one-clock cycle in hardware, hence it introduces zero latency.
  • 10x OPEX savings : Order of magnitude reduction in configuration, and ease of deployment
  • Overall CAPEX savings : Wiring, Power, Rackspace and Cost savings
  • 70+ customers interested in deploying within 1 month of shipping.
  • 10x High availability : N + M redundancy, health-monitoring and automatic failure handling
  • $15 Billion install-base can be leveraged: The technology has humongous market capture potential. It works on existing hardware. $15 Billion install-base of Nexus switches is able to use this technology.
  • 30+ patentable ideas: ITD has unprecedented innovations.

Cisco ITD (Intelligent Traffic Director) is a hardware based multi-Tbps Layer 4 load balancing, traffic steering and clustering solution on Nexus 9K/7K/6K/5K series of switches. It supports IP-stickiness, resiliency, NAT, (EFT), VIP, health monitoring, sophisticated failure handling policies, N+M redundancy, IPv4, IPv6, VRF, weighted load-balancing, bi-directional flow-coherency, and IPSLA probes including DNS. There is no service module or external appliance needed.


ITD has a lot of different types of use-cases. Some of these are:

  1. Create a multi-Tbps Firewall
  2. Create a multi-Tbps Video-cache
  3. Firewall/IPS/IDS/WAF load-balancing.
  4. Web Server load-balancing
  5. Application server load-balancing
  6. Replace WCCP. Redirect and Load-balancing traffic to Web-cache, WAAS, WAE
  7. Traffic steering to VDS/video-cache/Professional Media Network devices
  8. Load-balance to Hadoop/Big-data cluster.
  9. load-balancing to mobile equipment
  10. Load-balancing to Layer 7 load-balancers
  11. Replace legacy features such as ECMP, port-channel, PBR, etc

Tour the Cisco Allen Data Center

I had been looking forward to revisiting one of my favorite data center’s.  We had done this first back in 2011 and that video continues to do pretty well.

We had a chance to go back this year and one of the first things I noticed when we returned…it was filling up.  All the open floor space we shot the open for in 2011 was now filled and their were crews still pulling in fresh cable, racking new equipment and more. It was a busy place all night long.  (Watch the full tour)

One of the biggest reasons we returned was the growth in cloud services and the extensive use and build out of UCS of course, but now also ACI. The flexibility of this entire network relies upon the very use of technology that Cisco is developing. Its certainly on the mature side of course since this is one of Cisco’s primary production centers. As you would probably notice, its a beautiful, roomy layout that makes it desirable for touring. This is not common of course but it was built as a showcase for customers who want to see how things look when they all come together. The site is mirrored in Richardson, just a 20 minute drive South from this Allen location so that either site could take over and maintain operations for Cisco.

I am a big fan of all the physical facility innovation present here. These visual aspects would be appealing to a visual storyteller of course, but they also have not really changed since 2011. Read More »

Myth-busting: ACI or NSX, which is the Real SDN Leader?

I speak with customers every day and often hear they are confused by conflicting vendor claims, marketing hype and embellishments. This is especially true when discussing SDN, where both the technology and the market have evolved significantly over the past few years.

I’ve invited Frank D’Agostino, one of Cisco’s top technical experts on SDN, to join me in separating fact from fiction. Frank and I are on a mission to debunk trendy technology myths, and this is the first in a three-part video series that we’ll bring to you over the next week.

In this first episode, Frank and I discuss the differences between Cisco’s ACI and VMware’s NSX. Frank is in a unique position to discuss both technologies, since he’s the only expert that has been deeply involved in the development of both NSX and ACI.

We think that ACI and Nexus is the most complete solution on the market. It does everything customers want from SDN, while offering more capabilities than NSX, and being two to three times less costly in typical customer configurations.

Cisco also collaborates very closely with our customers on technology, and we work with a wide variety of industry leaders, including competitors, to offer the best level of technology integration and interoperability. The reality is that the choice between ACI or NSX is not “either or:” if customers want both, NSX can run on ACI just like any other application, and in fact NSX will run better over an ACI infrastructure than over any other infrastructure on the market.

Take a look at our first video below, and then compare for yourself which solution makes the most sense from the perspective of cost, performance, scalability, and features.

We look forward to reading your comments and feedback.

ACI and CITEIS Fortify the Cloud-Enabled Data Center

In July 2014, Cisco IT turned on the Application Centric Infrastructure (ACI) fabric for the first time in our San Jose engineering data center. Since then, we’ve been busy building out the ACI fabric in our U.S. production centers and beginning the process of migrating workloads. In phases, we’ll migrate our global infrastructure footprint to ACI within two years. Running on our internal cloud platform called Cisco IT Elastic Infrastructure Services (CITEIS), ACI provides flexibility and elasticity across the data center that wasn’t possible before. So far the results have been better than even we expected. Read More »
