Data Center 2009: How companies can build Green Data Centers?

Thermal management inside the server rack will ensure equal cool air disrtribution and that will minimise on energy cost and will help to save on energy and finally that wll create the green DC

Almost 40 percent of energy that flows into a data center goes towards power and cooling solutions. So raise the temperature in the data center as most data centers are run too cold, and raising the temperature by a few degrees often will not affect the equipment. And also according to a survey conducted on IT departments has revealed that IT depts don't even pay their own energy bills. So its better to install electric monitoring systems in place so that one can see the use of electricity go down due to the high rates they have to deal with.......

Going green is a great way to help your company financially while helping the world ecologically.One can use recycled or low-emission materials to build the data centre.Solar or wind power can be used to run the facilities.

Green data centers not only help in using less energy and save more money but it also provides a healthier work environment for employees and help to build positive relations with the surrounding community. Many states offer tax incentives to companies that build a green data center.
Scalable or modular systems can be used so that only the needed energy capacity will be used and in this way wastage of energy can be controlled.Synthetic white rubber roof can also be installed in order to dissipate external heat.

all the ideas Above !

Few points...

1. Low footprint.. (maximum utilisation of space/racks)
2. Consolidation of servers
3. upgrading to energy efficient servers
4. Effective power management 
5. Installation of high efficient power supplies.
6. Follow the standards.. energy star products

One of the key issues to green a data center  will be to reduce its carbon foot print.Data centers use 1 to 5 MWe  and major part of this goes towards dissipating the heat generated by the electronic equipment.Mostly the connected load for HVAC  exceeds  the  electronic eqipment loads in the data center.

Some of the reasons are as follows :

1. No containment of low /High temperature  bays
2. Use of refrigerative sytem to remove sensible heat.
3. Mindless use of redundancy 
4. No CFD analysis of internal  air flow and temperature  profiles 
5. Mixed Flow Ventilation, Poor use of underfloor ventilation
6. No economisers / No Free cooling used.profiles
7. Most data centers use outdated information on temperature set points.
8. ASHRAE recommend 27 deg inlet instead of 18 deg C 
9. It allows out let from the racks to reach 35 deg C
