What is GDPS?

IBM GDPS® is a collection of system recovery offerings on the IBM Z® platform, each of which uses services, clustering technologies, and server and storage replication and automation.

Learn how GDPS delivers IT resiliency and how it can be tailored to meet system recovery objectives:

GDPS executive summary

What are the benefits?

Resiliency to support multiple disk replication architectures, high availability, and disaster recovery at any distance from a single point of control – in seconds.

Flexibility to gain data consistency across both z/OS®, z/VM® and guests, plus open system data. GDPS also uses open architecture and is application independent.

Automation of operational tasks for availability and recovery with scripts.

Monitoring of your environment from a single point and in real time to detect any deviation that could impact resiliency.

Meet the GDPS solutions

GDPS Metro addresses the requirements of clients using synchronous replication (Metro Mirror) and is tightly integrated into Parallel Sysplex clustering technology.

GDPS Global orchestrates the recovery of systems that are using asynchronous replication (Global Mirror or z/OS Global Mirror).

GDPS Metro Global combines the local near-continuous availability of GDPS Metro with the unlimited distance recovery options provided by GDPS Global.

GDPS Continuous Availability uses near real-time replication to update data to a second instance of a workload in another location – and to manage the distribution of work across the two copies.

Logical Corruption Protection Manager enables secure point-in-time copies of the critical source data and methods needed to restore corrupted or deleted data back into production.

Footnote

Installation services include:
Synchronous Metro Mirror, Peer-to-Peer Remote Copy (PPRC), Asynchronous Extended Remote Copy (XRC), Asynchronous Global Mirror (GM) disk data mirroring, and software-based replication via IBM InfoSphere Data Replication for z/OS (for Db2®, IMS, and VSAM data using the GDPS Continuous Availability solution).

Disk replication protocols:
GDPS is designed to work with Metro Mirror (PPRC), z/OS Global Mirror (XRC) or Global Mirror disk replication protocols supported by the DS8000 family and made available to vendors. Some disk features require specific commands to be sent to the disk subsystem.
