The “China Sky Eye” data center is about to be built, and the world’s largest and most sensitive radio telescope will get rid of the problem of massive data



YonFair News, April 15th, it is reported that the FAST scientific research and data processing center project will be implemented in Gui’an New District, and the feasibility study report of the project has been approved by the National Development and Reform Commission. After the project is completed, “China Sky Eye” will finally complete the three complete scientific research frameworks of observation, scientific research, and data, which will provide supporting conditions for the storage and calculation of massive data generated by long-term operation.

It is understood that the FAST scientific research and data processing center has a total investment of about 170 million yuan, with a building area of ​​28,000 square meters, including the scientific research center to be built in the University Town of Gui’an New District about 20,120 square meters, and the Pingtang Tiantian Town The data processing center is 7,880 square meters.

Zheng Xiaonian, then deputy director of the National Astronomical Observatory of the Chinese Academy of Sciences, said during the 2017 Digital Expo that it is expected that FAST’s data volume will reach 100PB in the next 10 years. In fact, as the world’s largest and most sensitive radio telescope, “China Sky Eye” was troubled by massive amounts of data as early as the commissioning period. Especially after using the 19 beams, the “China Sky Eye” increased the peak data rate per second from 2G to 38G. Due to the limitation of storage and computing capabilities, the scientific team had to compress the data, but still faced the danger of data accumulation. .

After the official “post”, “China Sky Eye” will surely generate more “astronomical” data. According to the announcement issued by the Chinese Government Procurement Network, the National Astronomical Observatory of the Chinese Academy of Sciences has purchased a 30PB storage cluster for FAST data storage to meet the explosive growth of data storage challenges. The construction of the FAST scientific research and data processing center is even more urgent.
