11: Worldwide Green IT Case Studies 203

Future Plans During 2009

As highlighted in the preceding segment, various projects are being
planned to be undertaken in 2009. Some of these include the following:

■ Ongoing data center consolidation
■ Virtualization of computing power and storage
■ Centralization of an enterprisewide command center
■ Enhanced server consolidation
■ Implementation of Business Continuity Program

These projects contribute highly to the green environment efforts of IBM,
and lead to significant cost and performance benefits.

Chapter Summary and Conclusions

The following conclusions are from the discussion on green IT for data
ptg
centers around the world:
■ Although the challenges in implementing green data centers around the
world can vary considerably based on factors such as the cost of electricity
and social/political environment, the basic best practices remain the
same—for example, data center consolidation, server consolidation, IT
virtualization, and so on.
■ Green data center show cases such as the PSSC Data Center at Montpelier
can provide some valuable innovation ideas. Real-time dashboards show-
ing data center energy use (PUE) can help IT teams evaluate the impact
of different energy management policies (like the hybrid car’s miles per
gallon dashboard). Also, live cameras and thermal cameras can reduce
physical access and identify current data center hot spots, as indicated in
the Montpelier study.
■ The brief green data center discussion for Istanbul helps indicate the
growing worldwide interest in green IT and the cost and environmental
benefits of energy efficiency in all parts of the world.
