Green IT won't just happen: Strong, focused leadership will be required to drive meaningful change in concert with business objectives. Appointing a "VP of Green" now will allow IT organizations to help lead corporate green change, and not just be moved by it.

Featured Case Study
Wikibon reviewed the power measurements made on 3PAR’s InServ E200, S400 and S800 storage arrays. These arrays are built from standard components, and enable the power of different configurations to be calculated. The measurements were made at the component level.
The measurements were made across three different workloads:
- Sequential read, with a 512K block size
- Random read, with a 16K block size
- Idle (no data being transferred)
The results of the three workloads were averaged to produce an overall figure of power consumption for each of the components of the 3PAR arrays. Wikibon believes that the benchmarks used and the power measurements made were done professionally and in good faith. In the opinion of Wikibon, this measurement represents a good and reasonable estimate of the power consumed in real world applications across a number of drives for applications typcally found in a data center.

Featured How-To Note

Fluctuating energy prices have heightened electricity and energy consumption as a major issue within the technology community. IT is a significant consumer of energy and IT energy costs have been rising disproportionately because of continued investment in denser IT equipment. Estimates from the EPA and others indicate that IT will account for 3% of energy consumption by 2012.

Featured Case Study
The corporate IT group of a very large, worldwide financial organization with 100,000 employees, has initiated an ongoing “greening” process. This is focused largely on reducing energy use both to decrease the corporation's carbon footprint while creating a net savings in operational costs over the lifetime of new, more energy-efficient equipment, including new storage systems. This effort is not viewed by the IT administration as a one-time project but rather as a perpetual process of evaluating new technology in part on its energy efficiency and introducing it into the corporate data centers to replace aging systems as appropriate.

Fluctuating energy prices have heightened electricity and energy consumption as a major issue within the technology community. IT is a significant consumer of energy and IT energy costs have been rising disproportionately because of continued investment in denser IT equipment. Estimates from the EPA and others indicate that IT will account for 3% of energy consumption by 2012.
While technology changes have decreased footprint, power loading (amount of power required for a square foot of data center space) and heat load (the amount of heat that has to be removed from a square foot of data center space) have both escalated dramatically. The result is higher energy costs to provide power and extract heat from the data center, and lower utilization of data center floor space because of power and cooling limitations. The technology trends are toward higher heat and power loading, which will exacerbate the problem.
