• Storage Virtualization

  Controller-based storage virtualization dramatically simplifies the storage infrastructure by enabling the consolidation and aggregation of external heterogeneous storage resources in a single pool of enterprise storage capacity. Existing volumes and data on externally attached storage systems are discovered by Universal Volume Manager and presented through global cache as if they were on one system. Once virtualized behind the Hitachi storage system, external volumes gain access to all Hitachi storage services.
