High-End Computing Capability
Computing power to answer NASA's complex science and engineering questions
Archival Storage System
The NAS high-end computing environment includes a 380-petabyte tape storage system that allows science and engineering users to archive and retrieve important results quickly, reliably, and securely. Data stored on RAID is migrated to tapes as needed. Copies of users' data are written to two separate tape media in silos located in two different buildings. SGI's Data Migration Facility (DMF) and OpenVault manage data migration (disk-to-tape) and de-migration (tape-to-disk), respectively.
Our storage experts provide custom training to help users efficiently manage their large datasets, as part of the Supercomputing Systems services.
