Geographically Dispersed Disaster Restart

GDDR automates disaster restart of applications and systems in Mainframe environments in the event of planned and unplanned outages. Leveraging the Symmetrix VMAX architecture and the foundation of SRDF and TimeFinder Replication families, GDDR eliminates any single point of failure for disaster restart plans in Mainframe environments. GDDR provides support for disaster restart of applications and systems in Federated environments made up of Mainframe and Open Systems. GDDR supports single site and multi-site business continuity environments. GDDR intelligence automatically adjusts disaster restart plans based on triggered events.


 * GDDR for SRDF/Star with Autoswap: A 3-site business continuity solution based on SRDF/S synchronous data mirroring technology 200 kilometers (120 mi) apart and SRDF/A asynchronous data copying technology with no distance limitations that can be used in mainframe environments. In the event of a failure of a system or storage device, operations continue with limited or no data loss automatically between the SRDF/S sites or operations can be recovered with limited data loss automatically between the SRDF/A sites.
 * GDDR for SRDR/Star with Congroup: A 3-site disaster restart solution based on SRDF/S synchronous data mirroring technology 200 kilometers (120 mi) apart and SRDF/A asynchronous data copying technology with no distance limitations that can be used in mainframe environments. In the event of a failure of a system or storage device, recovery can occur with limited or no data loss between the SRDF/S sites or recovery can occur with limited data loss between the SRDF/A sites.
 * GDDR for SRDF/Star with EDP: A 2-site business continuity solution based on SRDF/EDP synchronous data mirroring and asynchronous data copying technologies that can be used in mainframe environments with no distance limitations. In the event of a failure of a system or storage device, recovery can occur with limited or no data loss automatically.
 * GDDR for SRDF/S with Autoswap: A 2-site business continuity solution based on SRDF/S synchronous data mirroring technology that can be used in mainframe environments 200 kilometers (120 mi) apart. In the event of a failure of a system or storage device, recovery can occur with limited or no data loss automatically.
 * GDDR for SRDF/S with Congroup: A 2-site disaster restart solution based on SRDF/S synchronous data mirroring technology that can be used in mainframe environments 200 kilometers (120 mi) apart. In the event of a failure of a system or storage device, a manual recovery can occur with limited or no data loss.
