Faster recovery with no extra cost

System Recovery Boost is a feature of IBM Z® introduced in IBM z15® that accelerates recovery from IPLs and other disruptive events by temporarily increasing capacity. It cuts recovery time by up to 50%2, doubles transaction backlog speed3 and improves batch throughput 2.5x4, with no increase in IBM software licensing costs.

Summary of changes for z/OS 3.1
Faster IPL recovery

Accelerate your return to pre-shutdown SLAs with boosts for shutdown and startup that provide extra processing capacity.

Faster Parallel Sysplex recovery

Accelerate recovery from sysplex events to expedite return to steady-state operations.

Faster recovery from other events

Reduce processing delays, minimize backlog and restore workload performance faster.

Faster automation

Accelerate IBM® GDPS® reconfiguration and orchestration actions for rapid, automated recovery.

Boost classes

Take advantage of three classes of boosts—each one with different capabilities and improvements.

See the prerequisites
Startup boost
A 60-minute boost, enabled by default to accelerate startup following an IPL
Shutdown boost
An optional 30-minute shutdown boost to accelerate shutdown for planned IPLs
Recovery process boost
Short duration boosts to accelerate recovery from a wide range of non-IPL recovery events
Accelerate recovery processes with the boost type that suits your system Speed boost zIIP boost System Recovery Boost Upgrade GDPS enhancements

Footnotes

IBM System Recovery Boost has no impact on IBM z/OS software license charges for subcapacity MLC or PLPA products.•

DISCLAIMER: Tangential effects on other LPARs, such as zIIP work spilling onto general-purpose processors because of a shortage of zIIP capacity as a result of IBM System Recovery Boost was not measured and can impact software license charges. Only partial hours of data (~15 minutes) were available to substantiate this claim. Only IPL boost was measured for pricing purposes. Sufficient data during shutdown periods was not available to substantiate this claim for shutdown boost.

IBM System Recovery Boost on z15, enables a z/OS partition to return to your preshutdown SLAs in up to 50% less time than on IBM z14®.

DISCLAIMER: z15 z/OS partitions benefit from System Recovery Boost for 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 composed of online transactions accessing WebSphere® Application Server, CICS®, IBM MQ, IMS and Db2®. Comparisons were made between z15 with System Recovery Boost and z14. Individual client results can vary.

z15 IBM System Recovery Boost provides extra capacity to your z/OS partition following startup to process your transactional backlog up to 2x faster than on z14.

DISCLAIMER: z15 z/OS partitions benefit from IBM System Recovery Boost for 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 composed of online transactions accessing WebSphere Application Server, CICS, IBM MQ, IMS and Db2. Comparisons were made between z15 with IBM System Recovery Boost and z14, with substantially comparable configurations. Individual client results can vary.

z15 IBM System Recovery Boost provides extra capacity to your z/OS partition following startup to process your batch backlog up to 2.5x faster than on z14.

DISCLAIMER: z15 z/OS partitions benefit from IBM System Recovery Boost for 30 minutes during shutdown and 60 minutes after activation. Measurements were collected in a controlled environment running an IBM developed workload under z/OS 2.4 composed of COBOL Batch jobs. Comparisons were made between z15 with IBM System Recovery Boost and z14, with substantially comparable configurations. Individual client results can vary.
