'IBM has revealed more about a PowerPC microserver it says will help to crunch data gathered by the square kilometre array (SKA), the colossal radio telescope to be built across South Africa and Australia.
Once operational, the SKA is expected to generate around an exabyte – a million terabytes - of data each day. Even sorting the junk is going to need plenty of computing power, but operations at that scale need to be frugal lest electricity costs alone make the SKA horribly expensive to operate.'
