This paper describes the technical features and technology used to ensure the integrity of long-term storage, the assured maintenance of content, and the management software employed to manage and operate Archive Storage and the entire storage system.

As an optimum storage infrastructure for the information lifecycle management of huge amounts of fixed content data typified by electronic documents and image data, an archive storage device (ETERNUS3000 Archive Storage) was released worldwide in June 2004.

This product is based on the hierarchical, Write Once Read Many (WORM) recording process dedicated to the storage of fixed content data, and combines a low-cost, high-speed disk array device with a high-capacity, interchangeable library device.
