EMULEX MODEL 355 SAN STORAGE SWITCH	CHAPTER 1: INTRODUCTION
USER’S GUIDE

FEATURES

The Emulex Model 355 SAN Storage Switch has the following features:

•High Performance Fibre Channel Switching:

•Wire speed non-blocking Crossbar switch core

•Single 12-port InSpeed SOC 320 ASIC with embedded SERDES

•Multiple simultaneous conversations between ports

•Traffic routed directly to destination ports

•2 Gb/s or 1 Gb/s performance across all ports

•Aggregate bandwidth of 48 Gb/s

•Supports cascades up to 3 switches and up to 126 host and storage devices

•No complex fabric services or buffers

•Effortlessly connects to any vendor’s fabric

•Patent-pending technology:

•Fairness and Prioritization–ensures that devices all have guaranteed access, or explic- itly have prioritized access, over all other devices in a system.

•Stealth™ Intelligent Change Manager–delivers maximum stability through automatic elimination of state and change notification system disruptions and unprecedented con- trol of disruptive events.

•Automatic Trunking–enables fully-multiplied throughput and bandwidth, failover pathing, and dynamic load balancing and device prioritization.

•Advanced diagnostics, performance monitoring, and fault isolation including continuous switch and port monitoring and automatic bypass of problematic or unused ports.

•Port Smart Settings, which are predefined port-level configurations that optimize switch performance and stability.

•One-Step Zoning, including overlapping/non-overlapping zones with port or AL_PA-based zoning.

•Switch management using the embedded http-based Web server, Command Line Interface (CLI), or Simple Network Management Protocol (SNMP).

•Half-rack, 1U size for easy installation (optional 19" rack-mounting kits available).

•Fibre Channel ANSI Standards Compliance

INSPEED™ TECHNOLOGY

InSpeed technology is an advanced switching architecture that couples a non-blocking crossbar switch with a unique switch port logic and per-port SERDES. This results in the industry’s highest density Fibre Channel switch on a chip (SOC). The port logic is based on Fibre Channel-Arbitrated Loop (FC-AL), an ANSI standard (X3T11) designed to provide shared bandwidth over low-cost media.

This architecture enables the switch’s router to send data directly from one port to another, allowing for multiple, simultaneous conversations between ports—effectively multiplying bandwidth. InSpeed provides the same performance as complex fabric switches that support FC-SW2. InSpeed™ can even exceed fabric switch performance in entry-level SAN environments, where the overhead associated with longer name addressing and services is not beneficial.
