IBM and Arm Partner on Dual-Architecture Mainframes

IBM and Arm have announced a strategic collaboration to develop dual-architecture hardware that enables enterprises to run Arm-based software on IBM mainframe systems, targeting AI and data-intensive workloads in regulated environments.

The partnership combines IBM's expertise in system reliability, security, and scalability with Arm's power-efficient architecture and expansive software ecosystem. Officials from both companies stated that the initiative focuses on three key areas: expanding virtualization technologies to allow Arm applications to operate seamlessly on IBM platforms like Z and LinuxONE; ensuring compliance with security standards and data residency requirements for high-availability operations; and creating shared technology layers to broaden software compatibility and deployment flexibility. This approach aims to help enterprises integrate modern workloads without disrupting existing investments in mission-critical infrastructure.

IBM highlighted the effort as a response to growing demands in sectors such as banking and insurance, where workloads often cannot migrate to public clouds due to regulatory constraints. By enabling Arm software to run alongside IBM's...
