With the third new release this year, Red Hat OpenShift4.17 is now generally available including for IBM® Power®. You can read the release notes here and find the guide for installing OpenShift 4.17 on Power here. This release builds on features included in Red Hat OpenShift 4.15 and 4.16, including an important update to multi-architecture compute that helps clients automate their modernization journeys with Power. Other updates and enhancements for clients deploying on Power focus on scalability, resource optimization, security, developer and system administrator productivity, and more. Here is an overview of key new features and improvements specifically relevant to Power:
Multiarch Tuning Operator
Included with Red Hat OpenShift 4.17 is an update to multi-architecture compute called the Multiarch Tuning Operator. The Multiarch Tuning Operator optimizes workload management across different architectures such as IBM Power, IBM Z, and x86, including single-architecture clusters transitioning to multi-architecture environments. It allows systems administrators to handle scheduling and resource allocation across these different architectures by ensuring workloads are correctly directed to the nodes of compatible architectures. The Multiarch Tuning Operator in OpenShift 4.17 further helps clients optimize resource allocation with policies that automatically place workloads on the most appropriate architecture. This also improves system administrator productivity and is especially useful with business-critical workloads that require high performance or need specific architecture capabilities, such as data-intensive applications often found running on Power.
