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

Strategy, Best Practices, and Solutions

The basic green IT strategy for any organization is based on the goal of
reducing IT energy consumption throughout the business. Emerging infra-
structure technologies, such as service-oriented architecture, virtualization,
and distributed computing, continue to offer businesses greater levels of flex-
ibility and efficiency of resource allocation and should provide the scalable
platform that every business requires. IT teams need to point to consolida-
tion strategies as popular techniques for fighting the flab in the data center.
Virtualization is also key because it allows for innovative and responsive
approaches for the allocation of computing resources. We also need to
understand that most of the time, corporations have mixed hardware
environments—unlike the environments in High Performance Computing
(HPC). This heterogeneous environment includes: various storage units
(NAS, SAN) and servers (high- and low-density, various IT vendors),
networking components, tape units, and robots. They have also mixed or
incomplete software environments, and IT infrastructure and IT resources
supervision are often disconnected. They are facing common limitations:
limited space, limited ceiling height in older building, limited height for ptg
raised floor, new and old equipment mix, old cabling, and water pipes. Back-
end cooling changes might not be an option.

PSSC Green Data Center of the Future Implementation

The main objective of the Products and Solutions Support Center (PSSC)
Green Data Center of the Future is to create a customer friendly real-time
green showcase production data center that can demonstrate a large percent-
age of the currently available best practices in IT and facilities energy conser-
vation, integrating at least one bleeding-edge major conservation technology.
The objective of the PSSC Green Data Center of the Future is a data center
dedicated to clients that will be an innovative leader in green data center strat-
egy. The showcase is based on a worldwide set of business scenarios and demon-
strations, and a dedicated room for new technologies introduction has been
implemented. An important point is that the Green Data Center of the Future is
being used in PSSC production mode, expecting energy consumption economy.
The main specifications of the PSSC Green Data Center are the following:
