Given the position of the energy in the society, it was inevitable that the data center world would also be overtaken by this issue. In fact the magnitude of the energy consumption by the data centers across the united states has has risen from 1.5% to 3% of the total energy consumed. The magnitude of this number is is large enough that it impacts quite number of concerns up and down the Silicon Valleys of the world. To put this in perspective. The United States consumes more that 12 GW of power annually (near 25% of the entire world). In 2006, the 3% data center power consumption amount of 4 GW of power is no longer insignificant. It is highly likely that this number will be still rising significantly, due to population increase, complete and total dependency on computers (internet/intranet), and mirror storage of data in multiple locations, and bulging of normal files due to higher resolution films, etc.
There are multiple factors in energy viewing the data centers, the actual housing, the heat producing componehts, the thermodynamics of the building, the actual energy consumption of the equipmet racks, the efficiency of heat dissipation from the racks, and the efficiency of earch rack from power consumption as well as heat dissipation of the individual equipment. Recently, the greenining of daa centers has become hot topic and units of carbon footprint is widely used on thie endeavor. There are number of papers on different componets of this subject, however, no single complete wholistic paper can be seen to cover.
The parameteric study of a typical data center can be grouped into the following:
• The building structure housing and location
• The Cooling system and distribution of the building
• The equipment rack system and equipment
The building structure housing and location
The building that houses the data center controls number of parameters in energy consumption of the data center. The newer buildings, depending on locationwere designed based on either state or federal energy laws. State of California has energy governing laws that dictates the maximum energy loss per square feet per year of the data center building. In most states, a department of energy energy software programor ASHRAE standard software is used in designing the heat loss on the building. In addition, better construction standard gives additional assurance for minimum energy loss through the building.
The location of data center, type of buildings, and exact location within a complex building data gives insight for better design f the building by the engineer. Given the asset value each data center, the liability for location selection increases dramatically. Generally, basements or dungeons of the building has become economically pleasing for the IT managers. However, given the 24 hour operation and the electrical cost of each data center, cenIn scanning the climatology of the location. Given the extreme variations where the entire population is becoming a totally paperless society and the data content are
