Founded: February 2006
Purpose: Formed to build metrics and provide better communications among data-center facilities and IT staffs, so that the people who pay the power bills (facilities) can work with the people who generate them (IT).
Key vendor participants: Advanced Micro Devices, American Power Conversion, Dell, HP, IBM, Intel, Microsoft, Rackable Systems, SprayCool, Sun and VMware.
Enterprise participation: AllState Insurance, British Telecom, Digital Realty Trust, Enterprise Rent-A-Car, News Corp., University of California San Diego and the Uptime Institute.
Work to date: Offers the Power Usage Effectiveness (PUE) and Data Center Infrastructure Efficiency (DCiE) metrics for tracking data-center power consumption.
Future work: Will provide workload-specific IT productivity metrics with the aim of enabling better planning and tracking of overall data-center power consumption. These metrics, for use with PUE and DCiE, should begin to appear next year.
Applicability scorecard: A-. The group has produced workable metrics and has key partnerships across the board with the U.S. Department of Energy (DoE), such groups as the Storage Networking Industry Association's (SNIA) Green Storage Initiative, and key enterprise users. One caveat: The Green Grid takes a broad look at the data center as a whole, and the result could be slowly evolving, less specific guidelines.
