Mainframe operating systems
Get power and precision
Mainframe operating systems are designed to manage the complex internal workings of enterprise computing, including memory, processors, devices, and file systems. IBM Z® operating systems build on this foundation, offering advanced security, scalability, and resilience to support mission-critical workloads in modern IT environments.
IBM Z mainframes support z/OS®, Linux®, and z/TPF, often running multiple operating systems on a single system. IBM z/VM® and KVM enable virtualization, running Linux, z/OS, z/TPF VMs, and Red Hat® OpenShift® on IBM Z and LinuxONE.
Each OS and hypervisor enhances security, resiliency, and agility, extending mainframe strengths to your hybrid cloud.
