Virtualization, Deduplication Helping the Green Cause

By Chris Preimesberger  |  Posted 2008-12-16 Print this article Print

Using virtualization to consolidate more workloads onto fewer machines, deduplication to process cleaner data and tiered storage to make best use of stored data has begun to pay the company back for its multibillion-dollar set of upgrades it is now undertaking.

Moving into 2009, the company has joined forces with the Green Grid, which has published some suggested power-saving metrics for next-generation data centers.

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.

Next-gen WAN optimization can speed up business and save energy.

Verizon, along with its biggest competitor, AT&T, has become a card-carrying member of the Green Grid and is putting its metrics to work in its data center networks.

Verizon generally has been the more aggressive of the two largest U.S. telcos when it comes to environmentally friendly strategies 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.
