System Recovery Boost is a feature of IBM zSystems™ introduced in the IBM z15® that reduces the time it takes to shut down and restart (IPL) a system, by temporarily providing additional processor capacity and throughput to a boosted LPAR.

Up to 50% less time to return to pre-shutdown SLAs, 2 times faster transactional backlog processing and 2.5 times faster batch backlog, without rising licensing costs or MSU consumption.

IBM System Recovery Boost improves shutdown and IPL, with short-term acceleration for specific system and sysplex recovery and diagnostic capture events in z/OS®.
