DESY s 1.7 mile-long PETRA III accelerator is a super microscope that speeds up electrically charged particles nearly to the speed of light approximately 186,000 miles per second and sends them through a tight magnetic slalom course to generate the most brilliant x-ray radiation of its kind. This synchrotron radiation is used by more than 2,000 scientists each year to examine the internal structure of a variety of materials with atomic resolution. A key challenge in this process is storing and handling huge volumes of X-ray data.
"A typical detector generates a data stream of about 5 Gigabit per second, which is about the data volume of one complete CD-ROM per second," said Dr. Volker GÜlzow, head of DESY IT. "And at PETRA III we do not have just one detector, but 14 beamlines equipped with many detectors, and they are currently being extended to 24. All this Big Data must be stored and handled reliably."
DESY is addressing this Big Data challenge with the help of
