Features and Capabilities

What's Inside

The email perimeter is under attack from many message-borne threats. Maintaining a high number of concurrent Simple Mail Transfer Protocol (SMTP) connections is fundamental to preventing denial-of-service attacks from affecting your system availability.

At the foundation of the C680 is the Cisco AsyncOS operating system. This OS supports up to 10,000 simultaneous connections per system, or 100 times more than traditional systems. And 64-bit processing magnifies the capabilities of system hardware for mail applications.

In addition, the C680 takes full advantage of our market-leading Cisco Unified Computing System (UCS) platform, providing a robust foundation for superior reliability and simplified deployment.
