Server Load balancing with NAT, using Nexus switches: ITD

Server load balancer (SLB) has become very common in network deployments, as the data & video traffic are expanding at rapid rate. There are various modes of SLB deployments today. Application load balancing with network address translation (NAT) has become a necessity for various benefits.

Cisco Intelligent Traffic Director (ITD) is a hardware based multi-terabit layer 4 load-balancing and traffic steering solution on the Nexus 5k/6k/7k/9k series of switches.

With our latest NX-OS Software 7.2(1)D1(1) (also known as Gibraltar MR), ITD supports SLB NAT on Nexus 7k series of switches.

In SLB-NAT deployment, client can send traffic to a virtual IP address, and need not know about the IP of the underlying servers. NAT provides additional security in hiding the real server IP from the outside world. In the case of Virtualized server environments, this NAT capability provides increased flexibility in moving the real servers across the different server pools with out being noticed by the their clients. With respect health monitoring and traffic reassignment, SLB NAT helps applications to work seamlessly without client being aware of any IP change.

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

BOI15_Data_Center_728x90

ITD provides :

  1. Zero latency load-balancing.
  2. CAPEX savings : No service module or external L3/L4 load-balancer needed. Every Nexus port can be used as load-balancer.
  3. IP-stickiness
  4. Resilient (like resilient ECMP), Consistent hash
  5. Bi-directional flow-coherency. Traffic from A–>B and B–>A goes to same node.
  6. Monitoring the health of servers/appliances.
  7. Handles unlimited number of flows.

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.

News@Cisco Week in Review and Look Ahead: May 2-6

Happy (late) Cinco de Mayo — or should I say Happy Cisco de Mayo!  It was another busy week here at Cisco.  Some of our top stories included features on the future of live sports distribution and customer networks.  Cisco also announced that it is now delivering containerized data centers! For more information, read below.

1.) To Stream or Not to Stream? The Future of Live Sports Distribution

There is an argument among TV broadcast networks that streaming live sports on the Internet and on mobile devices cannibalizes their TV ratings. However, the opposite appears to be true. Case in point is the March Madness basketball tournament this spring; the games were shown live on TV and also streamed live online. Interestingly enough, viewership increased in both domains. Perhaps live Internet streaming can happily live side by side with TV viewership, and maybe even enhance it. What are your thoughts?

You Can’t Stop Compute, You Can Only Hope to Contain It

Don’t put away the party favors yet.

Cisco a few weeks ago opened a new Data Center in Allen, Texas to fanfare that included media coverage and a ribbon-cutting ceremony with Texas Governor Rick Perry.

We’re now opening a Data Center in Research Triangle Park, North Carolina.  The facility features water-cooled cabinets, supports up to 25 kW per rack and has sophisticated monitoring and management tools for controlling power and cooling systems.  The Data Center can be configured with different levels of redundancy (up to tier 4), has a calculated PUE below 1.25 and is modular, allowing for rapid expansion.

Oh, and it’s tucked into a 40 ft. long box that can be delivered to your doorstep.  That’s right, Cisco’s newest server environment is a containerized Data Center.

The Cisco Containerized Data Center at Cisco's Research Triangle Park campus.

A formal grand-opening isn’t scheduled until August when an in-building Data Center opens its doors on the Research Triangle Park campus as well.  But you can watch the video below for a sneak peak at how it was installed as well as catch further discussion about Data Center container capabilities.

Additional information about the Cisco Containerized Data Center is available at www.cisco.com/go/cdc.
