Linux in the IBM Z ecosystem

By Elizabeth K. Joseph posted Tue March 26, 2024
The IBM Z ecosystem contains multiple operating systems, including IBM z/OS, z/VSE, z/TPF, and z/VM. So where does Linux fit in? First, let's talk about the terms surrounding Linux on the s390x chip architecture found in IBM Z and LinuxONE. IBM LinuxONE is a hardware product line. You can think of it as the sister brand to the IBM Z mainframe line, with similar hardware and specifications, but only running Linux. When people talk about running Linux on the mainframe, they often used to say "zLinux" and while this is expedient it has some challenges in that it creates the impression that Linux on Z is somehow different from Linux everywhere else — ...

Get your choice of Linux distribution on IBM LinuxONE

By Elizabeth K. Joseph posted Tue March 26, 2024
Which Linux distributions does LinuxONE actually run? Take your pick! You can choose from a wide range of officially supported and community-driven distributions.

Security and Cloud-Native Applications - IBM Z Crypto Express meets Red Hat OpenShift

By Adam Jollans posted Wed February 02, 2022
IBM Z and LinuxONE are renowned for the advanced security they provide, and are used by financial, government and other organizations across the world. Encryption is provided at a hardware level in two main ways – using the on-chip CPACF crypto accelerator, and through the IBM Crypto Express adapter. The Crypto Express adapter itself provides two main capabilities – fast asymmetric (public/private key) encryption for data-in-motion, and tamper-resistant protection of keys through Hardware Security Modules. Together, these can help protect the vital assets of organizations in their datacenters – from e-commerce to government to banks and fintechs. Meanwhile, ...
