Data Sheet

The Cisco® CSS 11500 Series Content Services Switch is a market-leading compact platform, delivering the richest Layer 4 to 7 Application Delivery services in the data center.

The Cisco CSS 11500, with the award-winning Cisco Web Network Services (WebNS) Software, is specifically designed to provide robust application delivery (Layer 4 to 7) services for Internet and intranet data centers in six key areas:

• It introduces an intelligent, distributed architecture to help organizations meet the real-world scaling requirements of today's application infrastructure.

• It improves application and site availability and transaction integrity by introducing Adaptive Session Redundancy (ASR), an industry standard in stateful failover.

• It delivers the greatest flexibility of any content switch in its class for customizing combinations of ports, performance, and services.

• It scales secured application transaction performance through support of an integrated, high-capacity Secure Sockets Layer (SSL) module. Off-loading SSL onto the network improves the overall performance of the web and application server enabling better application performance.

• It provides an integrated high-capacity web application (Hypertext Transfer Protocol, HTTP) compression module. Web application (HTTP) compression improves application response time by 20 to 50%, off-load the compression from the server, which reduces server workload, and decreases the traffic traversing wide area networks (WANs), which reduces bandwidth requirements and improves overall application response times; improving productivity.

• The Cisco CSS modular design protects investments by enabling upgrades of performance, ports, and services to meet your current and future application demands.

The Cisco CSS 11500 Series Content Services Switch enables businesses to simultaneously reduce costs by optimizing, scaling and securing data center, network, and application resources, which improves productivity of those resources, therefore offering a superior experience for customers, business partners, and employees. Through content fast switching and forwarding, the Cisco CSS 11500 Series improves utilization, responsiveness, availability, scalability, and security of Websites, server farms, cache clusters, firewall systems and many others application infrastructure components.

PREMIER TRAFFIC MANAGEMENT FOR E-BUSINESS

In addition to the Cisco CSS 11500 Series, Cisco Systems ® delivers a complete product line that includes the Cisco CSS 11501, CSS 11501S-C, CSS 11503, CSS 11506, and content switching modules (CSM/CSM-S) integrated service modules for the Cisco Catalyst ® 6500 Series Switch and Cisco 7600 Series Router. The Cisco CSM attains superior performance and offers transport and application (Layer 4 to 7) features as rich as those in WebNS Software. Through full integration with Cisco IOS ® Software, the Cisco Catalyst 6500 Series Switch, and the Cisco 7600 Series Router, Cisco CSM also supports high port density and comprehensive internetworking features. The Cisco CSM-S provides all the functionality of the CSM, and adds hardware acceleration of SSL processing. Together, the Cisco CSS 11500 and CSM are ideal choices for enterprises and service providers deploying content services.

NEW STANDARD IN HIGH AVAILABILITY

The Cisco CSS 11500 delivers Adaptive Session Redundancy (ASR), a method for achieving stateful Layer 5 session redundancy feature that enables failover of important flows while maximizing performance.
Some flows, such as a long-lived FTP or a database session, may be mission-critical, but many flows are not. Most of today's solutions require all traffic-important or not-to be backed up from one unit to another. If the majority of flows are not critical, most of system performance is wasted on unnecessary backups.
With ASR, the Cisco CSS 11500 can be configured so that critical flows are marked as replication-worthy, whereas others need not be marked as such. ASR focuses traffic management resources precisely where needed.

SSL AND COMPRESSION INTEGRATION FOR SECURITY, SERVER, AND WAN OPTIMIZATION

Cisco offers a scalable, hardware-based integrated SSL and compression solution. SSL, the industry standard for secure transport of traffic from client browsers to Web servers, presents two critical challenges for today's e-business infrastructure. First, because SSL encrypts data and headers, it obscures the request-specific information on which Layer 4 to 7 switching decisions are made. Second, SSL authentication places a high processing load for each SSL flow setup.
The Cisco CSS 11500 with integrated SSL modules meets both of these challenges by combining leading SSL acceleration technology with the Cisco WebNS technology. In addition to superior price performance, the SSL module simplifies the management of digital certificates.
The latest hardware module to be added to the Cisco CSS 11500 product line is capable of supporting both SSL acceleration and HTTP compression independently or simultaneously. This combination of supporting SSL transaction and compression in the same module delivers the following benefits:

• Server-based compression and SSL termination, intensive processes that can rob server performance needed for computational tasks; with this new module, network designers can offload these processes to the Cisco CSS 11500.

• Both secure and non-secure client traffic can enjoy the improved server response times associated with HTTP compression.

• SSL and compression capacity can be scaled by adding additional modules to the Cisco CSS 11500 Series.

• Network designers will see a reduction in WAN bandwidth consumption for both secure and non-secure Web traffic.

The compression module takes advantage of the decompression capability found in all Web browsers. Traditionally the compression responsibility was assigned to the server. Now, this task can be offloaded to the Cisco CSS 11500. This feature supports a lossless data compression algorithm and two file formats GZIP (GNU zip) and Deflate.
By combining support for SSL acceleration and HTTP compression, Cisco offers new possibilities in optimizing the switch-to-server architecture for data center security and optimization.

MODULARITY FOR INVESTMENT PROTECTION

Through its modular design, the Cisco CSS 11500 will meet your functional requirements today while providing for expansion for future needs. The Cisco CSS 11500 Session Accelerator Module is a cost-effective way to add performance for flow setup and flow forwarding. A selection of input/output (I/O) modules not only offers the choice of port densities of Fast or Gigabit Ethernet, but also boosts flow performance. Optional memory upgrades increase the number of simultaneous flows supported. PCMCIA Flash Drive is supported.

LOCAL AND GLOBAL LOAD BALANCING

A network designer can select one of two options for global server load balancing (GSLB) solution. The first option is to use the Global Site Selector (GSS), a dedicated GSLB appliance. In this design option, the Cisco GSS 4491 redirects clients to the best data center while the Cisco CSS 11500 is dedicated to the content switching process that involves selecting the best server within the data center. Local server selection is based on server load and application response time, as well as traditional least connection and round-robin algorithms.
The second approach is to have the Cisco CSS 11500 perform the both the GSLB and content switching duties. In this design option the CSS 11500 will select the best data center and the best resource within the data center.
The first design option should be used if the enterprise is planning to support more that one active data center, needs centralize GSLB management, or requires data center proximity solution. The second option is a good solution for one active site, and the objective is to failover to a secondary disaster recovery site. Any application that uses standard TCP or User Datagram Protocol (UDP) or DNS can be supported by either GSLB option.

SITE AND SYSTEM SECURITY

The Cisco CSS 11500 with Cisco WebNS Software helps ensure high levels of security without compromising site performance. The Cisco CSS 11500 provides stateful, content-based access control and supports security policies based on any combination of source address, destination address, protocol, TCP port, or URL. Wire-speed Network Address Translation (NAT) protects real server IP addresses.
For additional security, the Cisco CSS 11500 intelligently directs traffic across multiple firewalls. By load balancing firewalls, the Cisco CSS 11500 eliminates performance bottlenecks and single points of failure that result in system downtime, a situation that can close off the connection to the network and disrupt e-commerce purchases or other mission-critical transactions.

MANAGE THROUGH SIMPLE GUIS OR SOPHISTICATED TOOLS

Effective management tools reduce the ongoing cost of operating a business-critical Website. The Cisco CSS 11500 with WebNS supports a wide range of management tools that offer simplicity, security, and flexibility. For configuration, administrators have a choice of a Cisco IOS Software-like command-line interface (CLI) or an intuitive, embedded GUI. The Cisco CSS 11500 may be managed through enterprise management systems such as CiscoWorks CiscoView Device Manager (CVDM) and for large networks, tiered-access tools such as the Cisco Hosting Solutions Engine. For integration with customized management systems or even user applications requiring network interaction, the Cisco CSS 11500 offers an Extensible Markup Language (XML)-based, programmatic management application programming interface (API), Simple Network Management Protocol (SNMP), Remote Monitoring (RMON), and log files. Effective management tools reduce the ongoing cost of operating a business-critical Website.

CISCO CSS 11500 SERIES: CHASSIS AND MODULES

The Cisco CSS 11500 Series Content Services Switch includes four models:
