Mass Storage (MSS)

The NCCS Mass Storage System (MSS) is a multi-petabyte high-performance hierarchical storage system with high-speed network connections to the Discover supercomputer and other NCCS Systems. The MSS was designed to provide storage for important, but less-frequently used, data that serves NASA-sponsored science.

Yet, with the ever-increasing data output and requirements for increased resource efficiency, the NCCS is moving from the MSS to a combination of services including a Centralized Storage system for curated datasets, increased local storage for working datasets, and mechanisms to archive final data products at off-site facilities. The NCCS encourages its users to develop Data Management Plans to prepare for upcoming changes.

Centralized Storage System (CSS)

CSS combines high-performance computing and storage services into a single system to serve both traditional and emerging data analytics. Its centralized storage hosts commonly used, curated data products. CSS provides the flexibility to access and analyze petabytes of shared science data without requiring “wrangling” of large shared data repositories.

This filesystem will be available to all the NCCS compute environments (Discover, ADAPT, and DataPortal) as read-only. NCCS encourages users to share their data by requesting access and moving their final data products to CSSF. Data must fall under an active Data Management Plan; contact the NCCS User Services Group to get help setting up a plan.

// Data Collections

Available datasets on CSS include atmosphere, ocean, land, and flood data, both current and historical, as well as operational Global Modeling and Assimilation Office (GMAO) weather analysis data and forecasts that are updated four times daily.
