Data Center power density on the basic is the quantity of kW in terms of server BTU you are stacking in rack areas, and how much cooling it takes in the square footage they utilize.
There is a direct relationship between cost to build and density. The more power and cooling packed into a specific area, the higher the cost to build. However, the more efficiently you move hot air out and return it to cold air such as in higher density installations, the better your PUE is, and the lower your Operational Expenses (E) will be at your facility.
There are many different ways to address density.
Lower Density Data Center
- Spread computer loads around data center floor at lower density to evenly support those loads without containment
- Low cost method, can be achieved with floor air handler units, Air cooled systems, general ducting below floor or above drop down cooling.
- Higher PUE, higher operational cost per kW used
Mid-Level Density Data Center
- Set up cold and hot aisles to isolate the temperatures and airflow
- Semi isolation via rows only
- Aisle Containment options to completely isolate the hot and cold air
- Brings more cooling to servers, pulls hot air away more efficiently.
- Ability to direct more air into a smaller space to increase density of servers in one location
- Mid-level PUE, moderate operational cost per kW used
Higher Density Data Center
- Chimney racks to remove the hot air and return it to cooling system
- Local in rack system with containment allows for direct local cooling
- Total Rack containment Systems, hvac local in rack with local air exchange
- Lower PUE, lower operational cost per kW used
Our team can provide concept cooling designs, cost estimates, and site surveys for all sized projects.
