ATTO Technology 2500C Possible storage configurations

Introduction

ATTO ExpressNAV:

a web-based management

application that allows all of the configurable

settings for the iPBridge to be defined, viewed

and edited.

Connectivity, infrastructure solutions

The topology of a heterogeneous Storage Area

Network shown below demonstrates the critical

role ATTO products play in the design and

implementation of a SAN. Whether your

application needs are data-intensive or band-

width intensive, you need to store and manage

that data and then deliver it to end-users

efficiently. ATTO products have been engineered

with the highest performance and lowest cost

available today.
