Automated PBR and Route Health Injection with RISE

RISE is an innovative architecture that logically integrates an external service appliance such as Citrix NetScaler or the Cisco Prime NAM so that it appears & operates as a service module within the Nexus 7000 Series switches.
RISE integration with the Citrix NetScaler provides features like Route Health Injection (RHI) and Automated PBR (APBR) which allow easy configuration to redirect client and server traffic to the load balancer.

Automated Policy Based Routing (APBR)
Existing solutions to have server traffic return to the load balancer are Source NAT and PBR. Using Source NAT causes applications (server) to lose the visibility to client IP, burning IP address pool for Source NAT configuration and manual configuration. Policy Based Routing (PBR) requires complex initial configuration from the user (susceptible to human errors), configuration updates when a server is added or removed which can be cumbersome as the number of network devices and servers/VIPs grow.
  • Auto PBR eliminates the need for Source-NAT or manual PBR configuration in an one-arm mode design of load balancers
  • Preserves client IP visibility for applications/servers without the need for manual PBR
  • APBR feature allows the NetScaler to program policies on the N7K server-facing interfaces to redirect return traffic to the NetScaler appliance set up in one-arm mode
  • NetScaler passes information about real servers to N7K via the RISE channel and a policy is applied on the N7K interface through which the real server can be best reached
  • Since it is desirable to change the SRC IP to VIP for the return traffic, the APBR policies redirect traffic to the NetScaler IP without modifying the packet
  • The NS appliance will then direct the packet to the client by changing the source IP to VIP

Enabling Data Center Services with RISE : Remote Integrated Services Engine

Data Centers are becoming increasingly smart, intelligent and elastic. With the advancement in cloud and virtualization technologies, customers demand dynamic workload management, efficient and optimal use of their resources. In addition the configuration and administration of Data Center solutions is complex and is going to become increasingly so.RISE

With these requirements and architectures in mind we have a industry first solution called Remote Integrated Service Engine (RISE).  RISE is a technology that simplifies provisioning, out of box management of service appliances like load balancers, firewalls, network analysis modules. It makes data center and campus networks dynamic, flexible, easy to configure and maintain.

RISE can dynamically provision network resources for any type of service appliance (physical and virtual form factors). External appliances can now operate as integrated service modules with Nexus Series of switches without burning a  slot in a switch . This technology provides robust application delivery capabilities that accelerate the application performance manifold.

RISE is supported on all Nexus Series switches with services like Citrix NetScaler MPX, VPX, SDX and Cisco Prime NAM with many more in the pipeline.

Advantages & Features

  1. Simplified Out-of-Box experience : reduces the administrator’s manual configuration steps from 30 to 8 steps !!
  2. Supported on Citrix NetScaler MPX, SDX, VPX, and Nexus 1KV with VPX
  3. Supported on Cisco Prime Network Analyzer Module
  4. Automatic Policy Based Routing - Eliminates need for SNAT or Manual PBR
  5. Direct and Indirect Attach mode integration
  6. Show module for RISE
  7. Attach module for RISE
  8. Auto Attach – Zero touch configuration of RISE
  9. Health Monitoring of appliance
  10. Appliance HA and VPC supported
  11.  Nexus 5K/6K support (EFT available)
  12. IPV6 support (EFT available)
  13. DCNM support
  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

The Napkin Dialogues: “Open”-ing up to SDN

April 10, 2014 at 5:06 pm PST

I consider myself to be a reasonably intelligent individual. Well, perhaps “reasonably” is a debatable term; just ask my friends. Or my wife. (Then again, don’t ask my wife.)

Reasonable or not, though, I’ve been trying to wrap my head around what all this “software defined” stuff is supposed to mean, and I have to confess it’s been a bit circular: it’s almost as if you have to already know the information you’re trying to learn.

So where are the Napkin Dialogues written for people like me? Is everyone a super-genius programmer-cum-networker-cum-programmer and I just missed the boat? People are throwing around these “Open” terms left and right (e.g., OpenStack, OpenFlow, OpenDaylight, etc.) as if it’s an “open” and shut case.

Well shut. The. Front. Door. I’m going to have to be on the receiving end of my own napkin then. For me, it’s been feeling like I’ve been dropped into the middle of a maze with the lights turned off.

Yeah, kinda like that.

If you already ‘get’ this stuff, feel free to help a poor storage networking guy along in his journey, because I already know this iceberg goes all the way down.

To someone who is familiar with tried-and-true Data Center designs, I’m just having a hard time getting my head wrapped around 1) getting from here to there, and 2) just where there is! Read More »

Smithsonian Upgrades Network with Cisco Optical Solution and Switches

Good news.

The Smithsonian Institution and Cisco are collaborating to help the Smithsonian enhance the experience for more than 30 million visitors, who each year enjoy the services offered by the world’s largest museum and research organization. As an avid user of the Smithsonian’s 19 museums, nine research centers and more than 140 affiliate museums around the world, I support and welcome this great opportunity
