Danske Bank: Our 1000th Cisco ACI Customer!

A little over a year ago, we began shipping Cisco Application Centric Infrastructure (ACI).

Yesterday, Chuck Robbins tweeted that we hit our 1000th customer – Danske Bank, the largest financial institution in Denmark.

Our fast momentum and success with the Nexus 9000 (N9K) and ACI is largely due to our continued focus on customer needs – both now and well into the future. And our broad ecosystem of industry leaders has been and is committed to deliver integrated solutions for our mutual customers.

Just a little over three years ago, the team behind the N9K and ACI – Insieme Networks – began by listening to a variety of customers on what their business requirements were at the time and into the foreseeable future. What we learned is that modern enterprises were looking for an application-centric approach using open standards to deliver today’s business services.

Cisco Continues Mobile Core Momentum: Leads in Packet Core Market Share according to IHS Infonetics Research Data.

Well I told you that we would be back real soon with another update and here you go. As you remember we recently blogged that ACG Research again confirmed that Cisco continues to be the leading provider of Mobile Packet Core and Mobile IP Infrastructure over the past several quarters.

Now another analyst firm, IHS Infonetics Research highlights that Cisco has indeed increased our Mobile Packet Core in Lead to 24.9%, an increase of +4.5% points from Q1 2015 based on EPC / 3G Packet Core data in their report “Mobile Infrastructure Equipment for Q2 2015. That is three consecutive quarters in a row that IHS Infonetics Data has shown that Cisco has increased our market share for the Mobile Packet Core.

Five Keys to Success Leading Digital Business Transformation

As we explored in my previous blog, today’s rampant pace of innovation can be likened to a Digital Vortex, where ideas, technologies, and even entire industries are swept to the center of the Vortex — recombining and merging into disruptive new business models.

In such an environment, digital business transformation is critical — and demands decisive top-down leadership. Nevertheless, as our Digital Vortex research revealed, 45 percent of companies don’t consider digital disruption a board-level concern.

That represents a dangerous level of complacency, especially for market incumbents. We all know the names of seemingly immune incumbents that rested easy as innovative disruptors combined technologies into new business models — challenging and disrupting them from seemingly out of nowhere. Those disruptors were innovative, agile, and, of course, digital (see chart below from our Digital Vortex research).

ITD: Load Balancing, Traffic Steering & Clustering using Nexus 5k/6k/7k/9k

Cisco Intelligent Traffic Director (ITD) is an innovative solution to bridge the performance gap between a multi-terabit switch and gigabit servers and appliances. It is a hardware based multi-terabit layer 4 load-balancing, traffic steering and clustering solution on the Nexus 5k/6k/7k/9k series of switches.

It allows customers to deploy servers and appliances from any vendor with no network or topology changes. With a few simple configuration steps on a Cisco Nexus switch, customers can create an appliance or server cluster and deploy multiple devices to scale service capacity with ease. The servers or appliances do not have to be directly connected to the Cisco Nexus switch.

ITD won the Best of Interop 2015 in Data Center Category.

With our patent pending innovative algorithms, ITD (Intelligent Traffic Director) supports IP-stickiness, resiliency, consistent hash, exclude access-list, 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 provides order of magnitude CAPEX and OPEX savings for the customers. ITD is much superior than legacy solutions like PBR, WCCP, ECMP, port-channel, layer-4 load-balancer appliances.

ITD provides :

  1. Hardware based multi-terabit/s L3/L4 load-balancing at wire-speed.
  2. Zero latency load-balancing.
  3. CAPEX savings : No service module or external L3/L4 load-balancer needed. Every Nexus port can be used as load-balancer.
  4. Redirect line-rate traffic to any devices, for example web cache engines, Web Accelerator Engines (WAE), video-caches, etc.
  5. Capability to create clusters of devices, for example, Firewalls, Intrusion Prevention System (IPS), or Web Application Firewall (WAF), Hadoop cluster
  6. IP-stickiness
  7. Resilient (like resilient ECMP), Consistent hash
  8. VIP based L4 load-balancing
  9. NAT (available for EFT/PoC). Allows non-DSR deployments.
  10. Weighted load-balancing
  11. Load-balances to large number of devices/servers
  12. ACL along with redirection and load balancing simultaneously.
  13. Bi-directional flow-coherency. Traffic from A–>B and B–>A goes to same node.
  14. Order of magnitude OPEX savings : reduction in configuration, and ease of deployment
  15. Order of magnitude CAPEX savings : Wiring, Power, Rackspace and Cost savings
  16. The servers/appliances don’t have to be directly connected to Nexus switch
  17. Monitoring the health of servers/appliances.
  18. N + M redundancy.
  19. Automatic failure handling of servers/appliances.
  20. VRF support, vPC support, VDC support
  21. Supported on all linecards of Nexus 9k/7k/6k/5k series.
  22. Supports both IPv4 and IPv6
  23. Cisco Prime DCNM Support
  24. exclude access-list
  25. No certification, integration, or qualification needed between the devices and the Cisco NX-OS switch.
  26. The feature does not add any load to the supervisor CPU.
  27. ITD uses orders of magnitude less hardware TCAM resources than WCCP.
  28. Handles unlimited number of flows.

For example,

  • Load-balance traffic to 256 servers of 10Gbps each.
  • Load-balance to cluster of Firewalls. ITD is much superior than PBR.
  • Scale IPS, IDS and WAF by load-balancing to standalone devices.
  • Scale the NFV solution by load-balancing to low cost VM/container based NFV.
  • Scale the WAAS / WAE solution.
  • Scale the VDS-TC (video-caching) solution.
  • Scale the Layer-7 load-balancer, by distributing traffic to L7 LBs.
  • ECMP/Port-channel cause re-hashing of flows. ITD is resilient, and doesn’t cause re-hashing on node add/delete/failure.

Digital Business Transformation Starts with Five Key Leadership Questions

While digital disruption is overturning incumbents faster than just about any force in history, many business leaders are not getting the memo.
As I wrote in my previous blog, our recent “Digital Vortex” research found that nearly four in 10 top incumbents will be displaced in each industry due to digital disruption over the next five years. Nevertheless, 45 percent of companies don’t consider digital disruption a board-level concern.
