In the Lustre8 high-speed storage system for the Personal Genome Analysis division, we will be carrying out equipment maintenance work.

Medium nodes have been running on CentOS 7.9, but since Cent OS 7 is no longer supported (EOL) at the end of June, they are being migrated to Ubuntu Linux 22.04 in turn.

The period for accepting end-of-year account renewal applications for FY2023 is extended.
