3) File System: The file system is part of the MIDAS cluster resource and is an integral part of the cluster system. A second system element is primarily used to archive study results in the MREP warehouse. At present, the archival file system is configured with 2 terabytes (TB) of disk storage that will eventually be expanded to 14 TB. Users interact with the file system to associate simulation run I/O data locations with metadata that will be used to identify and tag achievable simulation results. The configuration control system also interacts with this system. 4) Relational Database System: The database management system platform will be housed by the MIDAS Web portal, which serves as the interface for electronic information exchange for the MIDAS network. The MIDAS portal is accessible to the public, but only registered users can access and provide information to the private section of the portal.
