The S-Series implements an industry-leading, ﬂow-based switching architecture to intelligently

manage individual user and application conversations—far beyond the capabilities of switches that are

limited to using VLANs, ACLs, and ports to implement role-based access controls. Users are identiﬁed

and roles are applied to ensure each individual user can access their business-critical applications no

matter where they connect to the network. S-Series policy rules combined with deep packet inspection

can intelligently sense and automatically respond to security threats while improving reliability and

quality of the user experience.

A signiﬁcant differentiator for the S-Series is the ability to collect NetFlow data at wire-speed on

every port, providing total visibility into network resource consumption for users and applications. The

S-Series is the only enterprise switch to support multi-user, multi-method authentication on every port

— absolutely essential when you have devices such as IP phones, computers, printers, copiers, security

cameras, badge readers, and virtual machines connected to the network. When quality of service, device

and application prioritization, and security matters there is no better choice than the Enterasys S-Series.

System Summary

The Enterasys S-Series family of ﬂow-based switches brings high performance distributed switching

to the network access layer, distribution layer, enterprise/campus core, and data center. The

S-Series family consists of the 8-slot S8, 6-slot S6, 4-slot S4, the 3-slot S3, 1-slot S1 and the ﬁxed

conﬁguration S-Series Stand Alone (SSA). The S-Series delivers some of the highest switching port

densities per rack unit available in the market and is future-proofed and scalable to provide overall

system capacities of up to six Terabits. All chassis support 802.3af and 802.3at (high power)

standards-based PoE via an integrated or ﬁeld installable power system. There are a variety of I/O

modules designed and optimized for deployment at the network access layer, distribution layer,

network core and data center that provide a broad array of connectivity options for copper and ﬁber

cabling infrastructures.

Architectural Overview

Forwarding Architecture

The Enterasys S-Series chassis utilize both fabric-based point-to-point and fabric-less meshed forwarding

architectures. The S1, 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.

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

S1, S4, S6, or an S8 chassis, however, the use of two I/O fabrics creates a load sharing fabric pair that

provides up to 1280 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 system with

two I/O fabrics installed will gracefully reduce the fabric switching capacity by 50% in the event of an I/O

fabric failure, however, when a third I/O fabric is installed the system will maintain a full 1280 Gbps of

switching performance if an I/O fabric module were to fail. The load sharing fabric architecture ensures

the highest availability and performance for the most demanding and mission-critical networks.
