Why that is so important?

Data Center (DC) is a specially organized technological site for server and telecommunication equipment, connected to high speed Internet and equipped with means of physical and information protection, fire-fighting and climate control systems, uninterrupted and backup power supply, high-performance equipment and software.

Each DC must be initially designed for continuous operation.

Commonly DC is a protected premise equipped with the following systems:

DC, as every industrial facility, is an expensive project in terms of initial investment and further facility operation. Thus while designing a DC it is important to give the highest priority to design quality and applied technological solutions. It is even more relevant currently, as the money value is very high and as a rule the market doesn’t give a second chance. 

Example, how you can make investment efficient.

In the below mentioned Business Case one might see how two main principles – modularity in construction and development, and implementing of energy-efficient technologies – included on the stage of design allow to obtain an economic effect.

The following Business Case provides for the construction of DC with technology of two alternatives:

  1. Classic approach – DC is at once constructed to the full capacity. Technology adopts classic process solutions.
  2. Modular approach – DC is constructed by stages in terms of space and required equipment. Technology adopts modern energy-efficient equipment. 

However external electric power for DCs is similar:

DC capacity limit, kW 1000
DC holding capacity, racks 300
Average capacity for one rack, kW 5
Discount factor, % 10

If to consider energy efficiency in another aspect, it is obvious that energy saving allows either to minimize the required capacity limit by reducing investment budget, or to use free capacity for additional racks.   

The effect of using released capacity as a result of application of energy-effective technologies is shown below:

  Traditional DC Energy Efficient DC
Power limit of DC:  1 000       KW        1 000        KW
Koeff. PUE: 1,5         1,2        
IT-load: 666,7       KW 833,3 KW
Power for cooling and other energy expenses: 333,3       KW
166,7 KW
If we accept that:
Average of IT- load per rack: 5     KW 5 KW
Number of racks:  133    167   
Average of price per 1 rack per month:  $1 500   $1 500  
Price cost per 1 KWh: $0,14   $0,14  
Income DC per month: $200 000    $250 000  

 

Also when PUE reduced from 1,5 to 1,2 additionally arises:

The economic effect of reducing the cost of electricity (in case the number of racks are constantly) be: $16800.00

Alternativelywe can estimate the the economic effect of converting the cost to income, namely:

As a result, we get a lower PUE release in the amount of of electrical power: 166,7 KW, which is equivalent to 33 racks with load 5 KW or additional $49500.00 income.
