This document discusses energy efficiency concepts and Cisco solutions for data centers. It notes that climate change is a pressing issue and data centers consume significant resources. Cisco offers products and solutions like storage virtualization, application delivery, and networked CRAC units that can incrementally improve power and cooling efficiency in data centers. Advanced services are also discussed to provide efficiency assessments, benchmarking, and help establish energy management strategies and implementations. Case studies show examples of potential energy savings through efficiency improvements.
