Syska Hennessy has unveiled a unique design for cooling datacentres that will allow companies to pack far more servers into a datacentre space. 

The engineering, technology and construction company is aiming the system, known as SmartServer Solution, at online banking and trading datacentres, or any centralised facility for the rapid transfer of large amounts of data. 

Based on a new way of thinking about air pressure and airflow design, the technology permits more servers per square foot than previous configurations, allowing users to site as many as 42 servers in a rack space that up to now could house only 24. 

According to Syska senior consultant Jun Yang, the company has used computational fluid dynamic analysis for room and server modelling. This has allowed it to configure the normal cooling elements currently available in datacentres in a more efficient way.

For example, Yang said that data centres typically placed the hottest equipment closest to the air conditioning, but that this was a mistake. 

"The air closer to the AC unit moves faster and can create a negative pressure, resulting in very little air coming out of the floor vent," Yang said.  

In a standard datacentre 1,460 servers require 353 racks and 8,800 square feet, and generate 90W per square foot. The company says that SmartServer needs only 34 racks and 1,664 square feet for the same number of servers generating 315W per square foot. 

At a rental cost of $25 (£14) per square foot per year, a space reduction from 8,800 square feet to 1,664 square feet  would produce an annual saving of $178,000 (£98,000).  

Syska's SmartServer is available now. The company will design new facilities or renovate old ones.
