Hitachi enterprise storage features the Universal Volume Manager function that can apply virtualization techniques to actual disk arrays, the world's first. With this function, Hitachi enterprise storage can consolidate multiple storage resources under uniform management while maintaining high levels of performance and reliability resulting in radical jumps in storage management and operation efficiency. The Universal Volume Manager can arrange data optimally on external storage devices that differ in scale and performance to enable cost-effective use of existing assets, and it can provide a platform for DLCM (data life cycle management) to raise the usage efficiency of all storage. It enables safe and easy migration between storage systems including those of other manufacturers, and can perform migrations during system operation without the need of intermediate servers. Hitachi enterprise storage supports Virtual Partition Manager function that provides dedicated storage areas for each server and the Universal Replicator function that provides enhanced replication power for disaster recovery.
