Overview

IBM Implementation Services for Geographically Dispersed Parallel Sysplex™, previously named IBM Installation Services for Geographically Dispersed Parallel Sysplex®, announced in Services Announcement 698-073 , dated November 24, 1998, has been renamed and enhanced. Using IBM Global Mirror and Geographically Dispersed Parallel Sysplex (GDPS™) technologies, you can implement and manage a disaster recovery solution which can potentially improve your Recovery Time Objective (RTO) and Recovery Point Objective (RPO).

Global Mirror uses breakthrough innovations within asynchronous peer-to-peer remote copy (PPRC) technology to perform disk mirroring, at virtually unlimited distances, with a RPO as low as three to five seconds. This new Global Mirror capability is designed to move data virtually unlimited distances while maintaining the consistency and integrity of both IBM eServer zSeries® and open systems data, providing a rapid restart of the application environment at the remote location.

Description

IBM Implementation Services for Geographically Dispersed Parallel Sysplex supports all transaction managers using automation technology to help manage your databases, processors, network resources, and storage subsystem mirroring. Your critical data is mirrored and automatically switched to an alternate site in the event of a primary planned site shutdown or site failure. There is virtually no limit to the distance between the primary and alternate sites.

IBM Implementation Services for Geographically Dispersed Parallel Sysplex has been enhanced to support Global Mirror for Enterprise Storage technology. Global Mirror uses breakthrough innovations within asynchronous peer-to-peer remote copy (PPRC) technology to perform disk mirroring at virtually unlimited distances with a RPO as low as three to five seconds. This new Global Mirror capability is designed to move data great distances while maintaining the integrity of the data to permit a rapid restart of the application environment at the remote location.

IBM Geographically Dispersed Parallel Sysplex (GDPS) Global Mirror is designed to provide business resilience and assistance with compliance with audit or legislative requirements by helping to reduce the risk of planned and unplanned business interruptions, keeping business systems running when an interruption occurs. The GDPS Global mirror is designed to automate:

  • Management of the disk volumes (initial configuration and configuration changes)
  • Ongoing monitoring of the integrity and recoverability of the environment
  • Management of the recovery test
  • Management of the fail-over at disaster recovery time

Global Mirror for Enterprise Storage provides a two-site extended distance remote mirroring function for z/OS and open systems servers. It is designed to provide a high-performance, cost-effective global distance data replication and disaster recovery solution. With Global Mirror, the data that the host writes to the storage unit at the local site is asynchronously mirrored to a storage unit at the remote site. A consistent copy of the data is then automatically maintained on the storage unit at the remote site using FlashCopy®.

GDPS Global Mirror helps simplify and streamlines the disk mirroring configuration tasks and is designed to provide monitoring capabilities to verify that the disaster recovery environment is maintained. It is also designed to provide an easily maintainable and testable automated process to bring up the zSeries recovery environments.

For clients who want to share their disk systems between the z/OS and open systems platforms, GDPS Global Mirror, running in a z/OS system, is designed to manage the disk replication status of devices that belong to the other platforms and are not even defined to the z/OS platform. GDPS Global Mirror is also designed to provide data consistency across both z/OS and open systems data. Additionally, concurrent activation of capacity backup can now be performed in parallel across multiple servers, which can potentially result in an improved RTO.
