Reasons and benefits of using JAXA Supercomputer System
Per business code unit, up to 100 TB of HDD storage is available, and at the same time, larger capacities can be written using tape drives.
Achievements of the Year
Alongside the preparations associated with the migration to J-SPACE, approximately 90 TB of telemetry data was stored on the HDD (/data) of JSS3, which allows writing without waiting for backup to J-SPACE.
