Lustre File System
NOTE Large systems such as Quartz, Jade, RZTopaz, and Zin have significantly more bandwidth to Lustre.
System details can be found on LC Confluence.

VAST File System
VAST is a high-performance all-flash, NFS-mounted, parallel file system available in the CZ, RZ and SCF. VAST is mounted on nearly all production compute systems in LC and is a good solution for data that will be accessed by heterogeneous clusters. VAST is also recommended for AI and transactional workloads with small files. VAST supports standard POSIX I/O but also has the potential to provide S3 access to data and serve as a database for on-filesystem data. Details on the VAST deployment can be found in Technical Bulletin #538.
| Center | Mount | Capacity (PiB) |
|---|---|---|
| CZ | /p/vast1 (/p/czvast1 on rzslic) | 8.5 |
| RZ | /p/rzvast1 | 1.0 |
| SCF | /p/vast1 | 4.0 |
