Storage Management
This element includes design and implementation of the mass storage system and its software. Included are the systems to provide the management of the storage of raw and processed data and retrieval of this data for reconstruction and analysis.
The storage of and access to the large volumes of raw and processed data will require the use of robotic devices in the computing center, and possibly elsewhere. The scope of this project includes provision for archiving of data to tape from the various input streams: Level 3, Production Farms, Derived datasets from Processing and Analysis. It also provides for reading of the data by Data Access, Production Computing and other systems, as well as the hierarchical storage management software needed to migrate data among shelf storage, robotic storage and disk.
Tracking and cataloging of data at all stages of the process via one or more mechanisms is required and software which optimizes access to the data is desired. The project is expected to consider and plan for more than one method of data storage and organization and to accommodate various stages of data processing and access requirements.
