Make The World A Better Place – Simplify and Automate Your Data Center

Last week, I wrote about Cisco’s SDN Strategy for the Data Center. I’d like to follow that up with 2 comments today.

  • A reminder of the fact that we’ll be doing a webinar tomorrow on this topic, and
  • A general observation regarding SDN making the world a better place (don’t roll your eyes yet.  There’s beer involved.  Well, kind of. Read on…)

The webinar is called “How To Simplify and Automate Your Data Center With Cisco’s SDN Strategy” and its tomorrow, September 15, 2015 at 10am PST. You can register here. We’ll spend a few minutes talking about ACI, then much of the time on Programmable Fabric and Programmable Networks. As the webinar name would imply, we’ll cover some cool tools that help make your life easier, if you have something to do with deploying and operating networks in a data center. We’ll have at least one demo and relate the technology back to some use cases, showing how SDN can be applied in practical ways.

As you consider the evolution of SDN over the past few years, its more or less gone from this thing with a limited definition (separation of control plane from data plane, etc.) that was kind of a solution looking for a problem, to a more loosely defined set of capabilities that are having real impact. There are still folks who define as SDN as “Still Does Nothing”, but I think that – even if you wipe away the hype from the media, analysts, vendors, etc. – SDN is making business more effective and helping make peoples lives better. I’m not talking like feeding the hungry, creating global peace type “make peoples lives better”.

I’m talking about the fact that most jobs have a certain amount of stuff that is cool/interesting/challenging/fun and another part that, well, just has to get done. The part that can be boring/laborious/mind numbing. A long time ago, I used to run a network. I would copy and paste configs from one box, make a few changes to IP addresses, or interface numbers, or ACLs, or maybe route redistribution metrics, or whatever – and paste them to another box. Rinse, repeat.   Many times. This was tedious stuff. And for the most part, not very interesting. Any activity with a lot of copy and pasting is probably better done by a machine than a human. But a lot of people are still running their networks in pretty much the same way.

There is a better way. SDN can help you minimize the ‘just have to get it done’ part of your job, so you can spend more time on stuff that is impactful and engaging. We will dig into this more tomorrow. So, maybe you won’t be displacing Mother Theresa, but you can make your world a better, more cool/interesting/challenging/fun place.  And have more time to drink beer.  Or do whatever it is you like to do.  In any case, I hope you can be there.

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.

ACI and Infoblox DDI Deliver Highly Automated, Secure, Reliable Core Network Services

Modern demands  in virtualization, cloud, and the Internet of Things are shifting the network landscape and require advanced solutions to manage critical network services across physical, virtual, and cloud environments.

Recently, I had the opportunity to speak with InfoBlox’s Chief Technology Officer, Alan Conley, about automating core network services – DNS, DHCP, and IP Address Management (DDI) – with Cisco Application Centric Infrastructure (ACI).  In this video interview, Alan spoke about the common challenges InfoBlox and Cisco customers face in security and automation in their data centers.

Alan eloquently explains how ACI micro segmentation to enhance security for East-West traffic in the data center complements InfoBlox’s secure DNS server that detects and mitigates malware and botnets trying to attack customer networks.

Alan Conley, InfoBlox CTO

He also shared how a number of InfoBlox customers are looking for the integration of InfoBlox DDI and Cisco ACI to deliver highly secured solutions but also ones that are operationally agile.

I really encourage you to listen to Alan Conley’s enlightening interview.
