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

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.
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.

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

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.
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
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.
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:
