2. IBM internal study designed to replicate a typical IBM customer workload usage. Results may vary.
3. IBM System Recovery Boost on z15 enables a z/OS partition to return to your pre-shutdown SLAs in up to 50% less time than on z14. Disclaimer: z15 z/OS partitions benefit from IBM System Recovery Boost for one boost period of 30 minutes during shutdown and 60 minutes during restart. Measurements were collected in a controlled environment running an IBM developed workload under z/OS 2.4 comprised of online transactions accessing WAS, CICS, MQ, IMS and Db2. Comparisons were made between z15 with IBM System Recovery Boost and z14. Individual client results may vary.
4. 99.99999% disclaimer: Internal data based on measurements and projections was used in calculating the expected value. The z15 servers must be configured in a parallel sysplex using z/OS 2.3 or above; GDPS management of data and middleware recovery across Metro distance systems and storage, including GDPS Metro Multi-site Workload and GDPS Continuous Availability; and DS888X with IBM HyperSwap. Necessary resiliency technology must be enabled, such as System Managed CF Structure Duplexing, Sysplex failure management and Capacity Provisioning Manager. Other configurations may provide different availability characteristics.
