Storage System Configuration
============================

The storage system disk space (total disk capacity: 5.07 PB) is divided into the user home directory area ``/home`` and ``/work``, which is used for temporary storage of program output and intermediate files.

A usage limit (quota) is set for each user in ``/home``, with a default value of 500 GB. If this limit is exceeded, you will not be able to write files. In that case, please delete unnecessary files or apply for a quota extension.

``/work`` can be used as a program execution area and temporary storage area for output files. Please create your own directory and set appropriate access permissions before using it.

For details, please refer to :doc:`/storage/how_to_use_storage`.
