Hitachi Copy-on-Write Snapshot Software

Copy-on-Write Snapshot software rapidly creates point-in-time snapshot copies of any data volume within Hitachi storage systems, without impacting host service or performance levels. Since these snapshots only store the changed data blocks in the Copy-on-Write Snapshot storage pool, the amount of storage capacity required for each snapshot copy is substantially smaller than the source volume. As a result, a significant savings is realized when compared with full cloning methods.

This product is enhanced by Hitachi Replication Manager, a new software tool that configures, monitors and manages Hitachi storage system-based replication products for both open systems and mainframe environments in a way that simplifies and optimizes the configuration, operations, task management and automation and monitoring of the critical storage components of the replication infrastructure.
