About
The Institute of High Energy Physics undertakes many large scientific engineering projects in China. These large scientific projects generate a large amount of data every year and require a computing platform for analysis and processing. Among them, the LHAASO experiment to be constructed in 2021 will generate about 6PB of data each year. EOS, as the main data storage system of the LHAASO data processing platform, has been deployed for online use since 2016. EOS was deployed at IHEP as the core storage system of LHAASO data processing platform and is used in production with strong support by the CERN EOS team. Currently, a total of 4 EOS instances are deployed, of which 3 serve LHAASO and HXMT experiments, and the other serves IHEPBOX. After multiple expansion in 2018 and 2019, the current total capacity is 8PB, and it is expected to expand by 6PB in 2020. The presentation will give an overview about the deployment status, issues encountered during the usage of new layout of JBOD's 84*12TB, and user experiences from using fuse to xrootd..
