Abstract: The Internal Battery Feature (IBF) is an optional feature on many of the IBM Z family processors. The IBF provides a local uninterrupted power source and further enhances the robustness of the power design present in the mainframe and increases a mainframe’s immunity to power line disturbance. It provides battery backup power to preserve processor data during a loss of power on all power feeds from the computer room. The IBF can hold power briefly during a brownout, or for orderly shutdown if there is a longer outage. The IBF will not be available on the IBM z14 Model ZR1 which introduces customers to another consideration when planning a new build or upgrade to this machine.
