IBM LinuxONE is a low-cost, scalable, enterprise-grade Linux server tailored to handle mission-critical workloads. It runs on IBM mainframes, especially IBM Z / IBM zSystems and IBM LinuxONE servers, and it is a great platform for open-source applications and vendor software, such as Oracle on Linux. Its main features are stability, low downtime, and the ability to replace 10-12 x86 cores with a single LinuxONE core, thus reducing the number of servers in a data center.
