2 IBM Systems and Technology Group Aspects of IT Business Continuity IT Business Continuity GDPS GDPS GDPS High Availability Fault-tolerant, failureresistant infrastructure supporting continuous application processing Continuous Operations Non-disruptive backups and system maintenance coupled with continuous availability of applications Disaster Recovery Protection against unplanned outages such as disasters through reliable, predictable recovery GDPS is designed for Continuous Availability and Disaster Recovery Page 3 IBM Systems and Technology Group What is GDPS? Integrated / Automated solution Manages application and data availability in and across sites Monitors systems, disk & tape subsystems Manages planned and unplanned activities System/disk maintenance / failure Site maintenance / failure Builds on proven high availability technologies Clustering Remote copy (disk and tape) Automation Easy to use interface Intuitive panel interface Policy based commands Page 4 2

Notes: Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here.
