Control

Intelligent controls integrated into room and row air conditioners allow these systems to maintain precise temperature and humidity control as efficiently as possible. They coordinate the operation of multiple cooling units to allow the units to complement rather than compete with each other, as sometimes occurs when intelligent controls are not present.

For example, one unit may get a low humidity reading that could trigger the precision cooling system’s internal humidifier. But before turning on the humidifier, the unit checks the humidity readings of other units and discovers that humidity across the room is at the high end of the acceptable range. Instead of turning on the humidifier, the system continues to monitor humidity to see if levels balance out across the room.

In one large data center’s carefully monitored retrofit application, adding intelligent controls to 32 Liebert Deluxe precision cooling units with integrated Liebert iCOM controls reduced energy consumption by 200 kW per hour, and generated a return on investment of 1.2 years.

Integrated control systems on room- and rack-based cooling systems can also be used to enable preventive maintenance programs and speed response to system problems. Data collected by these systems enables predictive analysis of components and proactive management of system maintenance. Event logs, service history logs and spare parts lists all support more efficient service.

The first decade of the 21st century was one of rapid growth and change for data centers. For most of the decade, data center managers were forced to react to rapid, continuous changes dictated by the capacity and availability requirements of their organizations, and the density of the equipment being deployed to meet those requirements.

Now, data centers must enter a new stage of maturity marked by a more proactive approach to management to enable increased efficiency, better planning and higher levels of service. Achieving actionable visibility into data center operations requires the ability to collect, consolidate and analyze data across the data center, using advanced devices, sensors and management software.

The 10 steps outlined by Emerson Network Power, and highlighted in this slideshow, provide a systematic approach to building the foundation for data center infrastructure management by deploying and leveraging measurement, intelligent controls and centralized monitoring and management. Data centers employing these 10 prescribed point solutions for infrastructure performance monitoring stand to gain an operational, strategic and transformative advantage for their enterprise or business.
