Heat - The Common Enemy
One common problem that occurs when there’s such a density of computers all in one location is the amount of waste heat produced.
For HPC cooling, this heat needs to be extracted and removed as quickly and as efficiently as possible. Loads can change considerably from one rack to another which makes traditional methods of air cooling very ineffective.
The resulting effect is often either having to work in really high temperatures or in hurricane like conditions as vast amounts of air are circulated in an attempt to remove the heat.
The simple tried and tested – and the most energy efficient, greenest - way of achieve HPC cooling is to use a Rear Door Cooler as used in many of our Data Centre Cooling solutions. This gives a neutral room condition, the air at the back of the rack is the same as the air on the front of the rack, it can operate within ASHRAE guidance, even with water temperatures of up to 27°C and gives the most system resilience, no matter where the load is at that moment in time.
