NCSA has over a Petabyte (PB) of raw disk capacity distributed among its High Performance Computing
(HPC) resources and other production systems. Several
additional Petabytes of archival storage capacity are available on-site.
Users at NCSA have a long-term data storage system at their
disposal, and access to high-speed parallel file systems on each of our HPC platforms to support the
creation and analysis of large data sets.
