COOLING FOR TODAY AND TOMORROW
This is the third technology insert on cooling produced with FOCUS magazine and things are moving along apace.
It was only a couple of years ago that data center layout, improving CRACs and air handlers and air speeds were the primary concern and any form of liquid cooling was being spoken about as technologies of the future.
Now we are talking about liquid immersion. Though yet to be widely adopted there are more solutions on the market and it and other seemingly outlandish ideas are entering the consciousness of data center operators as cooling issues in high density environments are becoming major concerns.
But while technology developments continue that are yet to become mainstream, there are also projects that need more efficient cooling now. The HLRS supercomputing center in Stuttgart, Germany, is at the forefront of a Europe-wide project which is looking at cooling across the data center.
Would you consider spraying water directly in the data center? The very idea of mixing liquid and electricity was too far out to be considered just a couple of years ago but now it is being deployed.
But deploying these solutions, and there are many out there, means working out just how much cooling is required and a good place to start is in calculating how efficient – or inefficient – your existing cooling set up is.
This technology insert is designed to help you consider today’s cooling issues and to plan for tomorrow’s.
