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

Multiple Platforms to Fit Any Environment

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, 4-slot S4, the 3-slot S3, 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 S4 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 S4

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 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.
