The Belle II experiment at the SuperKEKB collider in Tsukuba, Japan, has started taking physics data in early 2018 and plans to accumulate 50 ab-1, which is approximately 50 times more data than the Belle experiment. The collaboration expects it will require managing and processing approximately 200 PB of data.
Computing at this scale requires efficient and coordinated use of the geographically distributed compute resources in North America, Asia and Europe and will take advantage of high-speed global networks. We present the general Belle II the distributed data management system and computing results from the first phase of data taking.
