Earlier in this year, we were granted the privilege of joining an IBM Residency to create an IBM Redbook that describes creating Red Hat OpenShift in a Multiple Architecture Clusters on IBM Power. The publication intends to illustrate how to implement OpenShift in a heterogenous environment where IBM Power and x86 platforms are utilized. It also describes the benefits of using IBM Power as a controller (“control plane nodes”) in this mixed environment. This initial draft of the publication is the result of that Residency.

“Creating OpenShift Multiple Architecture Clusters with IBM Power” is an IBM Redbook that will help you install and implement an OpenShift environment in an IBM Power server environment along with x86-based nodes in a cluster.

The release of Red Hat OpenShift 4.14 brought the OpenShift Container Platform Multiple-Architecture Compute feature to IBM Power. Multi-Arch Compute provides a single heterogeneous cluster, enabling fit-for-purpose computing so clients can align tasks and applications to CPU strengths and software availability rather than one architecture. This support was expanded in Red Hat OpenShift 4.15 which enabled a Red Hat OpenShift cluster to support an IBM Power control plane and add x86 architecture worker nodes.

Multi-Arch Compute for OpenShift Container Platform lets you use a pair of compute architectures, such as ppc64le and amd64, within a single cluster. This exciting feature opens new possibilities for versatility and optimization for composite solutions that span multiple architectures.

This Redbook provides a high level overview of Red Hat OpenShift which can be run on many different architectures. We then present how IBM Power servers provide an extremely resilient and secure platform and how they can be an excellent platform for your cloud implementation using OpenShift. We then describe the benefits of using a multi-architecture cluster and provide implementation guidelines and advice to assist the reader in implementing a multi-architecture cluster using IBM Power control plane nodes and x86 or AMD based worker nodes.

This Redbook is suitable for many levels including managers that need to understand how OpenShift on Power can help meet their business needs as well as supporting technical staff that are responsible for implementing those clusters.

As this draft is still subject to further revision, please feel free to look through the Redbook and field any suggested edits to Carlo Castillo, Client Services Manager through [email protected] and we will gather your input and have our Redbook Residency team discuss any of your suggestions. Thank you and we hope this Redbook ultimately proves useful in your own IBM Power environment by taking full advantage of the power and extensibility of the OpenShift platform!

At the Masters®, storied tradition meets state-of-the-art technology. Through a partnership spanning more than 25 years, IBM has helped the Augusta National Golf Club capture, analyze, distribute and use data to bring fans closer to the action, culminating in the AI-powered Masters digital experience and mobile app. Now, whether they’re lining the fairways or watching from home, fans can more fully appreciate the performance of the world’s best golfers at the sport’s most prestigious tournament.

In a continuous design thinking process, teams from IBM Consulting and the club collaborate to improve the fan experience year after year. New features in 2024 include Hole Insights, stats and projections about every shot, from every player on every hole; and expanded AI-generated narration (including Spanish language) on more than 20,000 highlight clips.

The Masters has long relied on IBM to manage its data, applications and workloads across on-premises servers and multiple clouds, but this year marks an important evolution: the entire AI lifecycle is being managed on the AI and data platform IBM® watsonx™.
