What is IBM GDPS?
GDPS® is a multi-site or single-site end to end application solution that provides the ability to manage remote copy configuration and storage subsystems to automate Parallel Sysplex operation tasks and perform failure recovery from a single point.
GDPS helps automate recovery procedures for planned and unplanned outages for near-continuous availability and disaster recovery capability. You can have confidence that your key business applications will be available when your employees, partners and customers need them.
Benefits of GDPS
Supports multiple disk replication architectures
Building trust in public services
Drives failure recovery from a single point of control
Automates Sysplex operational tasks
Accesses z/OS and open system data
Uses open architecture and is application Independent
Key features
Takes resiliency to a higher level with GDPS and HyperSwap
GDPS is designed to quickly swap many devices, with minimal impact to application availability, and any disruptions measured in seconds. Working via GDPS, HyperSwap seamlessly substitutes Metro Mirror (peer-to-peer remote copy, or PPRC) and secondary devices for PPRC primary devices.
Delivers long distance disaster recovery in seconds of impact
Allows for unlimited distance replication with only seconds of user impact if there is a site disaster. By using software based replication techniques for copying the data between sites, IBM provides control over which workloads are being protected with active/active continuous automated availability (GDPS/AA).
Ensures the integrity of data in heterogeneous environments
Manages heterogeneous environments and assists to reduce infrastructure complexity. Installations can share disk subsystems between the z/OS and Open System platforms, while GDPS/PPRC manages the PPRC for Open Systems storage and provides data consistency across z/OS and Open Systems data.
