GDOC: Geographically Dispersed Open Clusters Providing Continuous Availability & Disaster Recovery for Distributed Systems

Geographically Dispersed Open Clusters (GDOC) is a high availability and disaster recovery solution for highly critical applications with aggressive recovery point and recovery time objectives. GDOC is a solution based on both IBM's extensive high availability and disaster recovery experience, and on high availability and disaster recovery software from Symantec. This white paper describes the GDOC solution in the context of distributed systems (such as AIX, Solaris, HP/UX, Linux, and Microsoft Windows) and it also describes an interface to Geographically Dispersed Parallel Sysplex (GDPS), IBM's corresponding continuous availability / disaster recovery Solution on mainframe systems (z/OS).
