EMULEX MODEL 375 SAN STORAGE SWITCH

CHAPTER 1: INTRODUCTION

USERS GUIDE

FEATURES

The Emulex Model 375 SAN Storage Switch has the following features:

High Performance Fibre Channel Switching:

Wire speed non-blocking Crossbar switch core

Single 20-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 80 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 explicitly have prioritized access, over all other devices in a system.

StealthTM Intelligent Change Manager–delivers maximum stability through automatic elimination of state and change notification system disruptions and unprecedented control 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).

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

Redundant fans and two hot-swappable, auto-sensing, load sharing, universal power supplies for high availability.

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.
