Immersion-1 Technical Details

In short, Immersion-1 is a massive immersion cooled FPGA cluster with 6048 Spartan®-6 LX150 FPGA chips from Xilinx. The FPGA chips sit on 1512 hot swappable boards and get power and communications from backplanes that are connected to the outside world.

While Immersion-1 is a fully functional unit that does indeed crunch numbers 24/7, it is also proof of concept that 2-phase immersion cooling is not just a dream of the future, it is a viable and elegant solution right here and right now.

Most importantly, our 2-phase immersion cooling approach cuts down engineering inefficiencies of legacy designs, lowers development and operational costs and results in a drastically lower carbon foot print. And all this while enabling us to pack the hardware in a never before seen density, keep the supporting infrastructure at a minimum and use our existing premises, instead of investing our life savings into large and remote co-location data center facility. In fact, with all that space saved, we could place our tanks at an ergonomic height for easy access - with plenty of headroom left.

 

Head Room

With all that space saved, there is plenty of room for expansion.

No Fans

Immersion-1 doesn't need fans, heatsinks or air channels.

Board to Board

Off to a good start, but current density is only scratching the surface of possibilities.

Silent and Dust Free Operation

Most of the time the only sound you hear is the hum of our high current main power cables. Once in a while, we work around the cluster and that's when it gets really "noisy": we have to turn on the air condition (Hong Kong has a hot and humid climate). Compare that with a modern data center facility where noise and dust is usually a real problem (typically 70-80 dB, using ear protectors in air cooled data centers is recommended).
