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

Cisco and Citrix Partnership will shine at Citrix Synergy 2014

April 28, 2014 at 6:30 am PST

CitrixSynergyCisco

In case you didn’t notice , the partnership between Citrix and Cisco has been growing nicely over the part 2 years in many areas .
Amongst numerous areas of collaboration here are some common solutions that will be highlighted at the coming conference Citrix Synergy

  • Cisco Enterprise Mobility solution for business to employee with Citrix XenMobile
  • Cisco Desktop Virtualization with Citrix Xen Desktop 7.1 on Cisco UCS
  • Cisco DaaS with Citrix (CloudPlatform or UCS director on UCS)
  • Cisco’s Citrix NetScaler 1000V  (vPath and RISE)
  • Cisco ACI strategy and how Citrix integrates OpFlex.

The last bullets point, especially the endorsement by Citrix of RISE ,  the new protocol for Nexus 7000  have been amply covered over the past weeks  in blogs from Gary Kinghorn  as well as video – You will find links at the bottom of this blogs. But check also Citrix page on Netscaler 1000V.

Citrix was  one of the close partner present  when we announced  last month at Interop  OpFlex, a new open standards- based protocol (OpFlex)  for Application Centric Infrastructure  (ACI) .In this video, Sunil Potti, Citrix VP & GM Netscaler,  explained why Citrix is standing shoulder to shoulder with Cisco on this topic.

Cisco and Citrix have been also working diligently to offer the best solutions in terms of mobility . You may want to check this blog from Jonathan Gilad on Cisco strategy and solutions around mobile workplace . Check his recent blog Beyond BYOD to Workspace mobility

Interop Redux: A Look at the New RISE Capability with Citrix NetScaler and Nexus 7000

April 11, 2014 at 11:00 am PST

Just prior to Interop about two weeks ago, Cisco unveiled its Remote Integrated Services Engine (RISE) on the Nexus 7000 series switch. Remote Integrated Service Engine (RISE) is a new protocol being added to the Nexus 7000 and 7700 platforms through NX-OS (software upgradeable to existing devices), that integrates external service appliances attached to Nexus 7000 Series switches with the same benefits as if the appliance was directly connected to the switch backplane, just like a dedicated service module. Initially, Citrix NetScaler Application Delivery Controllers (ADC) and the Cisco Prime Network Analysis Module (NAM) are the first services appliances that have integrated with RISE, and have been tested and Certified as “RISE-enabled”. With the announcement of RISE, we expect to develop an ecosystem of partners that will work with Cisco to take advantage of this technology, including other application services vendors and firewalls.

At Interop, I had a chance to meet up on the show floor with Citrix NetScaler Product Manager, Joe Peck, to talk about why Citrix is taking advantage of this new RISE technology.

But wait there’s more… Read More »

Nexus 7000 RISE Improves Network Integration for Cisco Prime NAM

April 7, 2014 at 5:00 am PST

Last week was a busy week in Las Vegas at another eventful Interop. In addition to our new announcements around ACI, we’ve been busy showing off our new Remote Integrated Services Engine (RISE) capability we introduced for the Nexus 7000 Series switch. Our introductory series on RISE concludes with a look at how RISE facilitates network integration of Cisco Prime Network Analysis Module (NAM) through the Nexus 7000.

Following our initial blog announcement last week, Andrew Lerner at Gartner took time from a busy Interop week to provide a nice blog on the RISE integration with Citrix NetScaler as well, which I encourage you to read here.

If you recall from my earlier posts here and here, RISE is the new protocol in the Nexus 7000 and 7000 Series switch that allows integration of a remote service appliance like NAM or an application delivery controller with the same functional capability as if it was attached to the switch backplane like an embedded services blade. Devices can actually be connected over any layer 2 network, and not necessarily directly connected to the Nexus switch ports, although that is the usual configuration. RISE-enabled ports are configured on the Nexus 7000 and up to 4 dedicated ports per appliance can be configured for maximum throughput to connected devices.

It’s a great benefit for appliance vendors to not have to develop specific network-embedded modules of their products to install inside the chassis, as well as saving valuable slots while providing the same degree of traffic visibility and optimization for the appliance. In this video, I had a chance to sit down with Praveen Chandra, Director of NAM Engineering at Cisco, to talk about the first Cisco service appliance to support RISE and what it means for Prime NAM customers:
