SKA will consist of 3 thousand small antennas, each of which will make an ongoing data stream. Data will be taken off from the telescope located in Australia or South Africa and then to be summed up and sent to scientists worldwide. Information processing will come down to collecting of data packets from each single antenna.
The Netherlands selected to IBM and Institute of radio of astronomy of the Netherlands (Netherlands Institute for Radio Astronomy, ASTRON) the five-year grant for the amount of $43.6 million covering expenses on creation of a specialized computer system of data processing of the telescope.
As soon as SKA works at full capacity, it will produce more than 1 exabyte of data a day (1 exabyte = 1 billion gigabytes). By estimates of IBM, these data will exceed the daily incoming traffic of a World Wide Web on volume.
Until it is also solved whether will be given to be flown down in the uniform data processing center (DPC) or it will be several of like those. One more task which needs to be solved is provision of energy of such large number of the equipment. It is necessary to configure also algorithms of data transmission according to an equipment configuration.
As a result highly productive system will be able to process from 300 to 1500 petabyte of data a year. It in tens times more, than makes the largest scientific generator of data in the world – the Large Hadron Collider (15 petebayt annually).
