CSS 11503 and CSS 11506 Module Overview

The CSS 11503 and CSS 11506 are compact modular platforms, delivering transport and application (layers 4-7) services for Internet and Intranet data centers. A CSS is a fully-distributed architecture with all modules in the system contributing to the overall processing and memory needs for flow set up. Performance increases incrementally as you add modules, and the modules balance the overall traffic load.

•The Cisco 11506 is a five-rack unit, supporting six-slots, with 40-Gbps aggregate throughput. The CSS 11506 requires at least one Switch Control Module (SCM) and may be configured with a second SCM in standby mode for redundancy. With the required SCM in one slot, the CSS 11506 has five additional slots supporting any combination of I/O modules.

•The Cisco 11503 is a two-rack-unit, supporting three-slots, with 20-Gbps aggregate throughput. The CSS 11503 requires an SCM and accommodates any two of the other modules.

Though all modules participate in flow setup, they differ primarily in control functions, performance, and I/O. Each CSS 11500 module consists of one high-speed MIPS RISC processor for flow-setup, one network processor for flow forwarding, one policy co-processor for search operations and a maximum of 288 MB of RDRAM (up to 256 MB of usable memory).
