Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(1)

OL-25090-01

Introduction

Introduction

The Cisco MDS 9000 Family of Multilayer Directors and Fabric Switches provides industry-leading
availability, scalability, security, and management, allowing you to deploy high performance
storage-area networks with lowest total cost of ownership. Layering a rich set of intelligent features onto
a high performance, protocol agnostic switch fabric, the Cisco MDS 9000 Family addresses the stringent
requirements of large data center storage environments: uncompromising high availability, security,
scalability, ease of management, and seamless integration of new technologies.

Cisco MDS 9000 NX-OS Software powers the award winning Cisco MDS 9000 Series Multilayer
Switches. It is designed to create a strategic SAN platform with superior reliability, performance,
scalability, and features. Formerly known as Cisco SAN-OS, Cisco MDS 9000 NX Software is fully
interoperable with earlier Cisco SAN-OS versions and enhances hardware platform and module support.
