The Cisco CSS 11500 Series Content Services Switch helps businesses to simultaneously reduce costs, by optimizing data center resources and boosting productivity, and offer a superior online experience for customers, business partners, and employees. Through content fast switching and forwarding, the Cisco CSS 11500 Series switches improve utilization, responsiveness, availability, scalability, and security of Web sites, server farms, cache clusters, and firewall systems.
The Cisco CSS 11503 and Cisco CSS 11506 are both modular platforms with interchangeable modules. The CSS 11503 and CSS 11506 may also share memory, disks, and gigabit interface converters (GBICs). The Cisco CSS 11501 has fixed memory and does support the same disks and Small Form-Factor Pluggable GBICs as the other two models.
The Cisco CSS 11506 requires at least one switch control module (SCM) and may be configured with a second in standby mode. With the required SCM in one slot, the CSS 11506 has five additional slots supporting any combination of I/O, Secure Sockets Layer, or session accelerator modules. The Cisco CSS 11503 requires an SCM and accommodates any two of the other optional modules.
