File system and data storage resources

The tables below provide basic facts about the GLADE file spaces and two different resources for storing data:

NCAR Campaign Storage
High Performance Storage System (HPSS)

For more information, see GLADE, Campaign Storage, or HPSS.

GLADE file spaces

See GLADE File Spaces for detailed information on use and policies regarding those spaces.

The /glade directories are identified as /gpfs in some output (from pwd, for example). CISL recommends using /glade in pathnames, as it is less likely to change in the future.
