The Data Center Pièce de Résistance
by Natesh Kannan Gopalakrishnan, Global Product Manager at Positronic
Data centers are surging. So are their energy needs. One large data facility can consume as much electricity as an entire U.S. city. This year, cloud computing will use 13 times the energy it did in 2012. In the U.S. alone, data centers are using an estimated 91 billion kilowatt-hours a year. Annual consumption is projected to increase roughly 47 billion kilowatt-hours by 2020, requiring the output of almost 34 giant coal-powered plants.
And new research suggests that data centers will soon be one of the biggest energy consumers on the planet, surpassing entire nations. To put it mildly, data centers are gluttons for power.
A Responsive Pièce de Résistance
With this massive demand, played out across countless racks of tightly packed equipment, even a small design improvement can make a big impact in energy and cost savings. Data center managers are ever looking to squeeze the last bit of performance out of center architecture, down even to the connector level.
Enter Positronic. Our power catalog features connectors with solid contacts machined from a high conductivity alloy. The resulting interface resistance values range from 0.7mΩ to 0.2mΩ, for the lowest resistance in the industry. With every individual contact contributing to power efficiency, the savings are significant when multiplied across the entire center.
Range of Resistance Values of Electrical Contacts
Low resistance increases the efficiency of an electrical connector.
Power loss at contact interface = I2R, a direct function of contact resistance.
Three technical elements can be optimized to create ULTRA-LOW Resistance electrical contacts.
1. Use high conductivity materials
International Annealed Copper Standard
2. Increase the electrical contact surface area. (Wipe line is longer than the inner perimeter of the female contact face.)
3. Optimize the force between the areas in contact
Positronic power connectors offer increased electrical contact surface area, the lowest circuit load in the industry, and highest linear current density – all resulting in more energy efficiency. And power efficiency and cooling are related, so if your power isn’t efficient, you’re spending too much money cooling!
