The Greening of IT
232 How Companies Can Make a Difference for the Environment

■ Power-capping a single server having a temperature problem, per-
haps because of an obstructed airflow, until the problem is solved
onsite.
■ Feeding power, temperature, and CPU usage data into the IBM
Tivoli Monitoring Warehouse. Using IBM Tivoli Usage and
Accounting Manager, this data can be correlated with accounting
data. Charge the IT users according to their CPU and correlated
power usage.

The opportunities are many, after the AEM data is available to the
Tivoli environment. As energy management begins to play an important
role, additional integration products from Tivoli are evolving. Due to
the flexible nature of the Tivoli toolset, user setup might be complex.
IBM services can help you find the best-fit solution.

Computer Manufacturers and Green Computing

All computer manufacturers are busy not only reducing energy use in ptg
the servers they produce, but are also working on making their own data
centers green computing examples. Here are case studies for some of the
major manufacturers based on news articles. Although there’s a market-
ing aspect to these articles, the emphasis on green IT is significant.

HP Green Computing
In 2008, HP announced initiatives to promote green computing and
reduce the company’s environmental footprint. HP’s goal is to reduce
power consumption 20 percent below 2005 levels by 2010 through
energy-efficient products and operating practices. The company, which
operates in more than 170 countries around the world, plans to meet its
energy reduction goal through more efficient products, internal opera-
tions, and supply-chain management. Recent innovations that should
help HP customers reduce power consumption include PCs with power
supplies that are 33 percent more efficient than their predecessors.
Furthermore, redesigned print cartridge packaging for North America
will reduce greenhouse gas emissions by about 37 million pounds in
2007, the company reported.
