The 2nd Edition

 IBM LinuxONE for Dummies - the guide to the most secure and scalable, enterprise grade, open source architecture, built for the hybrid cloud.

Why LinuxONE

Cloud native

Build AI-infused services that are developed and deployed anywhere across your cloud.

Encryption everywhere

Extend data privacy from LinuxONE to your enterprise through the use of policy controls.

Cyber resilience

Minimize the impact of internal and external attacks by isolating workloads to ensure continuous service.

Flexible compute

Use open servers designed for both start-ups and enterprises, as well as for public, private or hybrid cloud.

Meet LinuxONE III

Flexibility, responsiveness and cost are fueling your digital transformation and your journey to hybrid cloud. Now, you can drive to market faster—while avoiding cloud security risks and complex migration challenges.

LinuxONE III can transform your application and data portfolio with innovative data privacy, security and cyber resiliency capabilities—all delivered with minimal downtime.

Introducing IBM LinuxONE III Express

Available as a new cost-effective offering, IBM LinuxONE III Express can run your enterprise data for 57% lower TCO than when running on compared mid-market x86 servers.*

With industry-leading levels of performance, scalability, data privacy, security and availability, LinuxONE III Express is available in three sizing options to meet your workload demands.

This is an IBM internal study designed to replicate usage of a typical IBM customer workload in the marketplace. Results may vary. The workloads consisted of a transactional core banking application running on WAS and Db2. Eight instances of the core banking application were run with four instances representing a Dev/Test/QA environment and four instances representing a Production environment. Dev/Test/QA and Production environments were differentiated by their CPU utilization levels ranging from 3% - 20% utilization based on IT Economics client assessment x86 workload data. Average aggregate throughput was within 5% across all instances on both platforms in the internal study. On LinuxONE the banking application ran on RHEL 7.6 in two LPARs with z/VM 7.1, with 4GB and16 GB memory, and 4 virtual CPs. Total number of LinuxONE cores needed to deliver the workloads was 20. To achieve the same workload throughput on x86, the banking application ran on a total of 24 2-processor Sandy Bridge, Haswell, and Broadwell x86 systems, with speeds ranging from 2.4-3.2 GHz with a total of 448 cores. Actual tests were run on a z14 M04/LinuxONE Emperor II, which is rated within 3% of LinuxONE III LT2 Express performance, when configured with 12 cores. Both the x86 and LinuxONE environments had access to the same storage array. Total cost of ownership is defined to include hardware, software, labor, networking, floor space and energy costs over a period of three years. IBM software pricing is based on standard U.S. list prices with a 40% discount. LinuxONE Express, RHEL and z/VM pricing is based on U.S. prices as of May 2021 and x86 hardware pricing is based on IBM analysis of U.S. prices as of April 2021 from IDC. Floor space, networking, energy, labor and other x86 software costs are based on data from IBM IT Economics assessments for clients.
