Journey to LinuxONE content solution

IBM® LinuxONE is a platform for the Linux operating system built on a uniquely secure, reliable and scalable architecture. It is used in many different industries worldwide.

LinuxONE is available in single-frame and multi-frame servers, including an air-cooled single-frame server that is designed for business of all sizes. The latest LinuxONE servers can have up to 190 cores running at 5.2 GHz, and up to 40 TB of memory.

Use this content solution to understand how LinuxONE works, and to understand the experience of obtaining and installing a LinuxONE system.

What to expect

You work with IBM, and possibly a business partner, to understand your LinuxONE software solution, including the Linux distribution and other software. Key capabilities that have been validated for LinuxONE include the following:

  • Languages: Python, Pearl, COBOL, Java, Node.js
  • Management: WAVE, IBM Cloud Manager, Openstack, Docker, Chef, Puppet, VMware vRealize Automation
  • Database: Oracle, DB2LUW, MariaDB, MongoDB, PostgreSQL
  • Analytics Tools with Hadoop, Big Insights, DB2BLU and Spark

Of course, many others are available.

Linux distributions

Linux Distributions for LinuxONE are offered by RedHat and by Linux distribution partners Canonical (ubuntu) and SUSE, who provide services and support. IBM also offers services for all eligible Linux distributions for LinuxONE and support for the distributions from Red Hat and SUSE.


You can choose solutions from IBM software, open source software, and software from independent software vendors, such as Oracle. IBM collaborates with the Linux community and is one of the leading commercial contributors to Linux. Container images offer lightweight and self-contained software to enable deployment at scale. Use the following links to get a first look at supported software:

Storage and devices

Storage devices must fully conform to Fibre Channel Protocol (FCP) standard specifications. They must be connected using a storage area network (SAN) topology supported by LinuxONE (switched fabric recommended). Storage vendors must provide a support statement for use of the storage device with LinuxONE. In particular, the vendor must agree to perform problem analysis as IBM does not have access to these storage systems.

For NAS Storage, a support statement must come from the Linux distribution vendor, as they own the NAS Linux support. There is no support to boot from NAS in LinuxONE.

You work with IBM, and possibly a business partner, to understand the total cost of ownership of LinuxONE based on the solution that you have identified.

As a first step, you might do a sizing -- that is, answer the question, how big does each element of the solution need to be?

Total cost of ownership of LinuxONE can be lowered significantly, when compared with other platforms, by several factors, including:

  • Consolidating workloads. With LinuxONE, fewer servers can mean energy and space savings, and dramatically fewer cores can result in dramatically reduced software licensing costs.
  • Open source system software.
  • Support in the architecture for higher utilization, which reduces the tendency found with other architectures to provision more computing resources than are needed as a way to avoid bottlenecks caused by peaks in utilization.

A total cost of ownership calculator provides a personalized estimate for LinuxONE.

Work with IBM, and possibly a business partner, to plan to add LinuxONE to your data center. LinuxONE III offers:

  • Up to 4 19-inch frames, depending on your capacity requirements
  • Both raised and non-raised floor environments
  • Top and bottom exit I/O and power.

The steps for obtaining a new LinuxONE system vary, depending on your needs, but typically IBM:

  • Prepares a proposal
  • Discusses financing with you
  • Works with you to place an order
  • Builds and tests your system.

For planning details and a site planning checklist, see the manual for the LinuxONE server.

You work with IBM, and possibly a business partner, to set up and start your LinuxONE system.

IBM ships your system to you. IBM system service representatives:

  1. Unload and unbox your system at your location
  2. Verify that it is complete
  3. Move it into your data center
  4. Cable the system
  5. Bring it up.
