Chapter 2: Introduction

This chapter describes the ADIC Gateway. It provides the following information:

Overview

The ADIC Gateway is the interface between storage and Open System Host
interfaces and provides Fibre Channel to SCSI connectivity.

Configuration Support

The ADIC Gateway is a self-configuring product with Fibre Channel and SCSI
interface options. The ADIC Gateway can have up to four on-board UltraSCSI
channels and up to six SAN interfaces, which are configurable using plug-in cards.

Address Mapping

The ADIC Gateway maps addresses across and between these different
interfaces and preserves the persistency of the address maps across power ups
of systems, devices, and the ADIC Gateway. The ADIC Gateway supports the
attachment of up to 255 unique devices across multiple interfaces.

Interface Protocol Awareness

The ADIC Gateway processes SCSI-3 and SCSI-2 protocols for disk, tape, and
tape medium changer devices. It can report the host and devices that are attached
to its interfaces. The ADIC Gateway has the capability to manage the access
security between end points on the Fibre Channel interfaces and the SCSI
channels.
