Hitachi ShadowImage® In-System Replication software provides a nondisruptive, host-independent data replication solution for creating copies of any customer accessible data within a single Hitachi storage system. All ShadowImage copies are additionally RAID protected to ensure the highest data availability. ShadowImage copies can provide immediate, nondisruptive access and sharing of information for decision support, test and development; or to optimize tape backup operations. By enabling backups to run concurrently with production, ShadowImage software increases the availability of revenue producing applications. ShadowImage software disk-based copies can provide nearly instant recovery from data corruption.
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.
Features
- The high-speed, nondisruptive full volume local mirroring technology of Hitachi ShadowImage In-System Replication software rapidly creates multiple copies of mission-critical information within all Hitachi storage systems in mainframe and open systems environments.
- ShadowImage software keeps data RAID protected and fully recoverable—without affecting service or performance levels.
- Replicated data volumes can easily be split from the host applications.
- For Hitachi Universal Storage Platforms and Hitachi Lightning 9900™ V Series enterprise storage systems, the ShadowImage software consistency group function allows a user-defined group of ShadowImage volume pairs to be split simultaneously, at a precise moment in time, with a single command.
- Optional Hitachi ShadowImage Compatible Mirroring for IBM® FlashCopy®. The ShadowImage Compatible Mirroring for FlashCopy is functionally compatible with the IBM FlashCopy feature and supports data-set-level copy. With support for both IBM DFSMSdss commands and TSO Peer-to-Peer Remote Copy (PPRC) commands, ShadowImage Compatible Mirroring for FlashCopy operations can be performed for the z/OS host system and additional copies can be made.
Benefits
- Shortens restart and recovery times with the consistency group function, which provides multivolume, point-in-time copies for applications and databases that share or span multiple volumes.
- Reduces recovery from data corruption time dramatically through the ShadowImage QuickRestore feature, which allows an immediate restore to a disk resident, point-in-time data copy.
- Replicates large data volumes without impacting service levels, timing out or affecting performance levels.
- Reduces testing and deployment time and increases the accuracy of application development by providing always-available copies of current production data.
- Increases competitive advantage through the ShadowImage QuickSplit function by facilitating the sharing of and immediate access to time-critical information for decision support, populating data warehouses, performing analysis or other data mining operations.
- Enables normal backup operations on a copy of up-to-date production data while critical applications continue to run unaffected.
Quote
"With transaction volume surging year after year, we identified a strong need for an enterprise-class integrated storage system and a need for efficient backup of data. Therefore, we decided to promote integrated disk management and introduction of internal data replication function."
—Park Kyeong-jeon IT Manager, Korean Federation of Community Credit Cooperatives (KFCC)
