Large Project in India (Over 30 Data Centers)
ptg
This green data center case study is for a large project involving 35 data
centers of about 200,000 sq. feet of data center space. Most of the case study
information was provided by Ramesh Goel and Chris Molloy of IBM.
Primarily driven by the need for improved efficiency and cost reductions,
the case study includes the results of consolidating the 35 data centers to
seven data centers. In addition to data center consolidation, server consolida-
tion and virtualization were among the many efficiency and cost-saving
improvements. However, this was a green data center project, and the electric
power savings due to these data center efficiencies were part of the project
and goals from the beginning.

The Solution: Work with the Experts

As the company’s business grew, there was increasing pressure on the man-
agement to focus on IT in terms of planning, budgeting, and implementa-
tion to scale it to support business growth. As IT became more complicated,
it seemed more prudent to hand it over to a trusted partner that could man-
age all the requirements including applications, networking, hardware, IT
staff, and the data centers.
