With the performance of CPU processors becoming more and more powerful and the number of core processors increasing, the negative impact of power consumption is becoming more and more serious. The electricity charge with more ordinary people is nothing, but for companies with huge data centers like Google and Microsoft, the increase of power consumption is a big trouble.
An important cost of data center comes from power consumption and heat dissipation. When the power consumption is high, not only the electricity cost is high, but also the heat dissipation system costs a lot of money. Air cooling is no longer available. Many data centers begin to use water cooling and oil cooling.
But that's not enough, because the power consumption and heat are still too high,AMD's 64 core Xiaolong processor has a TDP of 280W,Intel's 10nm Icelake SP series will also reach the TDP range of 250w-300wCompared with the previous 100w-200w, it has improved a lot.
Now large data center companies have big brain holes, and even consider throwing servers into the sea to cool down. Microsoft, Google and other companies are studying this cooling method.
In fact, Microsoft launched a pilot project as early as 2018. On June 1, 2018, Microsoft sank a cylindrical data center about 12 meters long and nearly 3 meters in diameter into the bottom of the Orkney Islands in Northeast Scotland. This device is wrapped with 864 servers and can store 27.6 Pb of data.
After two years of operation, Microsoft has fished out the server on June 1 last year,The results show that all aspects of the performance are better than the traditional data center, the failure rate is only 1 / 8 of the latter.
Of course, this technology is still in the research stage, the experimental server is still relatively small, the scale of large data center is much larger, and long-term experiments are needed.
