IBM has announced significant advancements in its mainframe hardware and software ecosystems. The company revealed details for its next-generation “z18” processor, which features a dual-ISA strategy to natively support both traditional IBM Z and Arm (AArch64) instruction sets. This hardware, built on a 2nm process, includes AI inference acceleration and advanced memory management systems designed for the IBM Z series and LinuxONE platforms.

Complementing these hardware updates, IBM introduced a Statement of Direction for ‘IBM Z Atlas,’ an AI-native solution intended to manage mainframe environment complexity. The tool aims to map the z/OS stack to automate patch management, regulatory responses, and impact assessments to reduce unplanned outages. Additionally, UNICOM Global announced that its solutions are prepared to support the IBM z/OS V2.4 operating system and newer versions of COBOL and PL/I to assist in digital transformation.
