Footnotes
¹ ITIC 2023 Global Server Hardware, Server OS Reliability Report
² For clients running z/OS v2.5 and common IBM software stack on IBM z15 and higher, users can expect up to 99.999999% availability when the configuration includes an enabled Parallel Sysplex, System Recovery Boost (SRB), GDPS, DS8K with HyperSwap, and best practices.
DISCLAIMER: Based on IBM internal data. Necessary components include: IBM z15 or IBM z16, IBM middleware subsystems (CICS v5.4, IMS v15.2, MQ v9.2, Db2 v12, Websphere, or later), supported by z/OS Parallel Sysplex, DS8000 Series storage, GDPS HyperSwap Manager (HM) and GDPS Continuous Availability (CA). A minimum of three member systems with workload-level availability and redundant components are required, with a third data center serving as a continuous availability Disaster Recovery site. IBM Middleware subsystems must be deployed with redundant regions in conformance with high availability best practices: https://www.redbooks.ibm.com/abstracts/sg248446.html . Other configurations may provide different availability characteristics.
