With the Internet now firmly established as a social infrastructure, the ownership and management of diverse types of digital data is generating considerable expense. To manage this ever increasing amount of data, Hitachi proposes "DLCM (data life cycle management) solution," a comprehensive storage technique that optimizes the cost of data ownership as the value of data changes over time. Hitachi enhanced its midrange disk-array subsystems to provide a hardware platform for the DLCM solution. It provides nearline storage by supporting SATA (serial advanced technology attachment) disk drives in existing midrange storage products, and provides robust data storage solutions by supporting antidata-tampering functions. Furthermore, with the addition of the 9585V upper-midrange model with enhanced performance, Hitachi also supplies online storage at top-class performance in the midrange market. Hitachi provides a complete lineup of products for achieving a multi-tiered storage platform.
