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 the 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.
