This IBM® Redpaper publication introduces System Recovery Boost (SRB), which is a firmware feature that was introduced with IBM z15™ and enhanced on IBM z16™. SRB delivers substantially faster system shutdown and restart, short duration Recovery Process Boosts (RPBs) for sysplex events, and fast catch-up of an accumulated backlog of mission-critical workloads after specific events (such as system restart).
SRB is a firmware feature that is available on IBM z15 and IBM z16 central processor complexes (CPCs), and it requires operating system support for use. It is available on older systems. Always check the latest firmware and software for available SRB functions.
The IBM Z server generations that are described in this paper are available as the following machine types and models (MTMs):
