Intelligent Storage Systems in Digital Preservation

Great effort has been expended in making digital preservation repository systems reliable in terms of how they manage the objects within the repository. For the most part, these systems place no more demand on the storage system in which they store their digital objects than any software system places on a POSIX file system. All issues of integrity maintenance tend to be handled by the preservation system itself. For example, regular fixity checks are typically carried out by the preservation system running through its catalog inventory and reading each file stored in the storage system in order to compare with a previously calculated hash value stored in the catalog. This requires the attention of the preservation system itself in most cases. Large simplification and performance gains are to be made by delegating more of these integrity checking and data recovery issues to the storage system.
