Energy Savings & Return on Investment

Before realizing the full financial benefit of the energy savings and reduced downtime provided by SynapSoft™ 6.0 , you must first baseline the data center and focus on airflow management, which will create the opportunity for cooling system improvements. Once this is done and combined with SynapSense Active Control™, you can save up to 50% of cooling costs.

Wireless Sensors & Data Center Airflow Management

Using a network of SynapSense wireless sensors, data center operators are able to visualize air mixing, see trends, and identify hot spots. In addition, high-sensitivity sub-floor grids of pressure sensors target poor flow areas and floor leaks.  Empirical evidence shows that a four inch square opening in the floor (commonly used to route rack cabling) is equivalent to an entire perforated tile.  Plugging holes and adopting other airflow management steps cost very little but can make a huge difference in the effectiveness of the CRAC air supply efficiency. Estimates show that these basic steps alone can save between 1-3% on the total annual energy bill for the average data center.

Wireless Sensors & Cooling Effectiveness

Once basic data center airflow management problems have been solved, the next step is to begin increasing CRAC set points.  According to Ray Pfeifer, SynapSense Corporate Executive Vice President and Chair of LEEDs Committee for Data Centers, “Each degree of increase in CRAC set point translates to about 1.5% savings in energy costs. This can add up to tens to hundreds of thousands of dollars per year for a large data center.”  Also, if airflow management is improved, there is less fluctuation in temperature, causing less risk in the data center.

SynapSense Active Control leverages a granular deployment of leading edge wireless sensors used to measure server inlet temperature and sub-floor pressure differential to dynamically manage CRAH temperature set points and variable fan speeds. This unique approach to control optimizes cooling capacity and saves up to 50% of cooling costs by minimizing the fan energy to meet server CFM requirements, while maintaining acceptable server inlet temperatures. This allows data center operators to add IT load, while avoiding the capital cost associated with incremental cooling capacity.

Fiscal Return on Investment

Once the first steps have been taken using the SynapSoft™ 6.0 companies are typically able to reduce their data center energy consumption by 10-20%.
