Case study on Green Data Center 2
What is data center? Use and functions of Data Center. Basic Infrastructure requirement for data center. Energy consumption heads in data center. 3
What is Data Center Installation of large number of networked computer servers and data storage equipment for digital services is called Data Center. 4
Use and Functions of Data Center Finance Stocks Medical Education Governance Commerce 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 5
Basic infrastructure Requirement of data centre. Data Center Building Data Center Hall Meet Me Room Configuration area Battery Rooms UPS Rooms BMS Room Security Control room Efficient Electrical Power System with UPS & standby DG Utility Block with efficient chiller & cooling tower STP/ETP Plant Administration Building 6
Energy consumption in Data center Major Power consumers in Data Center are IT servers Data Storage Utility services Air Conditioning system Infrastructure-Lighting, Elevator etc. STP/ ETP Plant 7
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. 8
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 9

Different Airflow Configuration in Server Racks Most common Method Inlet Air to Server Exhaust Air from Server 14
Aisle containment 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. 15

Steps for Sustenance Modern Lifestyle demands more energy To Generate more power, Large fossil fuel are used Fossil Fuels lead to High GHG Gas Emission High GHG Emission leads 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 17
Green Impact By following the IGBC Green guidelines we have seen the direct impacts on Power Carbon Foot Print Money 18
Food for thought 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. 19
