Data storage centers represent a major investment for any organization. This is true in terms of the value of the data to be stored as well as the physical infrastructure itself. Maintaining this investment requires implementing an environmental control system that has been designed to accommodate the needs of each particular storage center. Overheating is a serious threat to the function and longevity of storage center devices; however, the high cost of energy has led many companies to explore new approaches to cooling options.
The Basics of Hot Aisle, Cold Aisle
A hot aisle, cold aisle approach is a data center configuration solution that uses air flow to disperse heat. Managing air flow is an excellent way to manage cooling costs through a simple form of energy conservation. Though hot aisle, cold aisle configurations have a number of variations, at their most simplest it consists of server racks in rows with cold air intakes facing one way and hot air exhausts facing the other in a pattern of alternating rows.
The aisles designated cold face the air conditioner’s output ducts. The hot aisles are positioned facing the air conditioner’s return ducts; they receive the outpouring of warm air from the cooling system’s exhaust. To prevent the cold and hot air from mixing and thereby diluting the cooling power of the environmental control system, containment measures have to be put in place. Traditionally containment was achieved through physical barriers. Though straightforward, this approach to containment did not fully realize the potential of this particular configuration. It is now more common to combine barriers with sophisticated variable fan drives. Plenums are part of the system’s configuration, too. A plenum is a space where air is allowed to circulate; it is separate from other spaces and is a traditional part of many building-wide ventilation systems.
Implementing a Hot Aisle, Cold Aisle Configuration in Your Data Center
There are best practices outlines that can be referred to when considering the implementation of this particular data center configuration. These standards include:
- Automatic doors in the data center: These help manage air flow and temperature
- A raised floor: A floor height of approximately 18 inches provides space for environmental control equipment
- Device arrangement: Placing devices with top or side exhausts in their own section prevents air flow disruption
- Rack grills with an optimal output: Select rack grills with output ranges of 600 cubic feet/meter
