Reduce overall complexity in existing environment in order to adapt to changing businesses need with a framework approach.

Improve productivity and reduce expenses via consolidation and virtualization of expensive resources across current environment without impacting existing businesses.

Offers the ability to differentiate existing services and maintain SLAs for a mixture of disparate applications & user groups.

Enhanced business agility by offering the ability to turn on new apps and services in minutes instead of weeks or months in existing environment. Presentation_ID © 2006 Cisco Systems, Inc. All rights reserved. 4 Critical Infrastructure for Data Center 3.0
