Hitachi ShadowImage
Hitachi Data Systems provides innovative, storage-based technology solutions
for enabling continuous business operations. By partnering with customers to
understand key business challenges and requirements, Hitachi Data Systems
is able to deliver robust, application-focused storage solutions that enhance
operational efficiency and resilience.
An essential component of business continuity and risk mitigation strategies
and optimized IT operations is the ability to replicate data quickly for critical
application processing, testing and development of new applications, zero-
downtime recovery, data migration, and necessary backup operations. The
high-speed non-disruptive local mirroring technology of Hitachi ShadowImage
In-System Replication software rapidly creates multiple copies of mission-
critical information within Hitachi storage systems in mainframe and open-
systems environments. ShadowImage keeps data RAID-protected and fully
recoverable without affecting service or performance levels. Replicated data
volumes can be split from the host applications and used for system backups,
application testing, and data mining applications while business continues to
run at full capacity.
ShadowImage provides heterogeneous replication between any storage
systems within a virtualized storage pool managed by the Hitachi Universal
Storage Platform V. Data that resides on an externally attached storage
system can be moved from the source to a target data volume anywhere in
the storage pool, including to another externally attached system. Using
ShadowImage, you can migrate data volumes from one platform to another
through the Universal Storage Platform V and maximize the use of your
storage infrastructure. By providing non-disruptive, high-speed data
replication within any Hitachi storage system or within the virtualized storage
pool, Hitachi ShadowImage software enables immediate use of data in decision
support, software testing and development, and data protection operations.
ShadowImage for z/OS is functionally compatible with the industry-standard
IBM
®
Peer-to-Peer Remote Copy (PPRC) host software functions. PPRC TSO,
PPRCOPY ICKDSF and/or Hitachi Business Continuity Manager™ commands
may be used to perform ShadowImage for z/OS operations on the USP V
system.
This document describes and provides instructions for performing
ShadowImage for z/OS operations on the Universal Storage Platform V using
the ShadowImage for z/OS software on Storage Navigator and using PPRC
TSO or PPRCOPY ICKDSF commands. The licensed ShadowImage for z/OS
software displays the ShadowImage information and allows you to perform
ShadowImage operations. For further information on Storage Navigator,
please refer to the Storage Navigator User’s Guide (MK-96RD621).
