OLCF users have many options for data storage. Each user has a series of user-affiliated storage spaces, and each project has a series of project-affiliated storage spaces where data can be shared for collaboration. The storage areas are mounted across all OLCF systems, making your data available to you from multiple locations.
A Storage Area for Every Activity
The storage area to use in any given situation depends upon the activity you wish to carry out.
Each User has a User Home area on a Network File System (NFS) and a User Archive area on the archival High Performance Storage System (HPSS). User storage areas are intended to house user-specific files.
Individual Projects have a Project Home area on NFS, multiple Project Work areas on Lustre, and a Project Archive area on HPSS. Project storage areas are intended to house project-centric files.
The following sections contain a description of all available storage areas and relevant details for each. If you’re the impatient type, you can probably get right to work by adhering to the following simple guidelines:
