What is Data Center
Confidential Reliance Jio Infocomm Limited
Installation of large number of
networked computer servers
and data storage equipment for digital services
is called Data Center.

5. 5
Use and Functions of Data Center
Confidential Reliance Jio Infocomm Limited
Data centers are back bones of Digital life.
They are prerequisite for ATM operation, Point of sale transactions
& even very simple applications like Booking a cab.
Data Centers are providing Digital Content like Videos, Music,
Books & Digital services like Google, Facebook, Twitter
Finance Stocks Medical
Education Governance Commerce

Case study of Two Data Center
1. First Data center designed & constructed in the
year 2009 based on conventional design at that
time.
2. Second Data Center designed & constructed in
year 2013 based on improved green design
concept.

• Basic design basis
• Electrical design basis
• Air-cooling system design basis
• Reliability improvement
• Different Air-flow configuration in the server rack
• Most efficient configuration
• Comparison of actual operating data of energy
consumption
• Awareness of Green concept
• The conclusion

The cold aisle provides cold air directly to front
side of all the racks and hence to the servers,
while the hot aisle receives the warm air
discharged by the servers.

to Global
Warming
IGBC Green
Guidelines to
reduce global
worming
To reduce the chain effect of power demand to
global warming impact we have to follow the IGBC
Green Guidelines

18. By following the IGBC Green
guidelines we have seen the direct
impacts on
• Power
• Carbon Foot Print
• Money

Green Impact
Confidential Reliance Jio Infocomm Limited

19. • Different server
manufacturers adopt
different configuration of
server Air flow pattern.
• Cooling performance gets
affected by the same.
• Uniform approach as
explained with Hot aisle
containment will improve
the PUE.
• Requesting IGBC to discuss
the air management
standardization with all
server manufacturer.
