Virtualization, Deduplication Helping the Green Cause
The Green Grid is a global consortium dedicated to advancing energy efficiency in data centers and business computing ecosystems. The nonprofit group is focused on defining meaningful, user-centric models and metrics; developing standards, measurement methods, processes and new technologies to improve data center performance against the defined metrics; and promoting the adoption of energy-efficient standards, processes, measurements and technologies.
Here are some of the key data points in the Green Grid's recent whitepaper (PDF), "Green Grid Metrics: Data Center Infrastructure Efficiency (DCiE) Detailed Analysis."
- Complete knowledge and understanding of each component in the data center and its power requirements.
- Knowledge and charting of total facility power; data center input power; power for building lighting, security and cooling.
- Knowledge and charting of minimum measurement at interval power: Level 1 (week/month), Level 2 (daily) and Level 3 (continuous).
- Knowledge and use of the DCiE formula, which is as follows: IT equipment power divided by total facility power; this figure comprises the actual DCiE.
In order for DCiE to become a global metric, two important requirements that all must follow are:
- The data center manager must correctly classify each subcomponent that comprises the metric's two core contributors; and
- The data center manager must obtain the data inputs that create DCiE's two core contributors in the same method; i.e., utilize a consistent method for data capture; actual measurements must always be used.
Verizon and AT&T both have begun implementing these data points.
