In late May, I had a chance to visit CERN , near Geneva , and visit with Jakub Mościcki, head of CERN ’s Storage and Data Management Group in the CERN IT Department and Alberto Di Meglio, head of IT innovation, including CERN openlab. CERN conducts one of the world’s largest science experiments and the facility houses the world’s largest particle accelerator, the Large Hadron Collider . We had a discussion and tour of CERN ’s main data center and I also got to see the antimatter factory .
This group also supports cloud and infrastructure storage including home directories, block and object data access. The image below, from my briefing, gives an idea of CERN storage services and its support of experiments, users and data centers. Ceph provides block devices for compute services such as batch and interactive clusters, while CERNBox provides storage for data analysis integrated with end-user access to data on edge devices.
Regarding future plans for archiving, CERN will continue to use magnetic tape but they are also looking into other data archiving technologies, including optical storage approaches such as those of Cerabyte and Project Silica . They are also keeping an eye on using DNA storage for archiving applications.
