Forwarding Paradigm
The Enterasys S-Series chassis utilize both fabric-based point-to-point and fabric-less meshed forwarding architectures. The S1A, S4, S6,
and S8 chassis use a fabric-based forwarding architecture that provides multiple high bandwidth data paths between I/O modules, while
the S3 chassis provides a high performance, fabric-less meshed forwarding architecture ideally suited for highly available network edge
wiring closet deployments. All chassis are optimized for redundant high performance switching and routing as well as providing flexible
connectivity and the ability to add features and scale performance as required and as new technologies become available.

connectivity and the ability to add features and scale performance as required and as new technologies become available.
I/O fabric modules provide scalable, high performance data paths as well as a full complement of front panel interfaces with flexible
modular interface options. A single I/O fabric may be used in either an S1A, S4, S6, or an S8 chassis, however, the use of two I/O fabrics
creates a load sharing fabric pair that provides up to 2560 Gbps switching capacity and adds high-availability features. The S8 and S6
chassis augments the load sharing fabric pair by allowing the addition of a third I/O fabric module, increasing the system reliability and
performance in the unlikely event of an I/O fabric failure. An S8 or S6 system with two I/O fabrics installed will gracefully reduce the
fabric switching capacity by 50 percent, in the event of an I/O fabric failure, however, when a third I/O fabric is installed, the system will
maintain a full 2560 Gbps of switching performance. The load sharing fabric architecture ensures the highest availability and performance
for the most demanding and mission-critical networks.
