IBM z/OS Cloud Broker system requirements

Operating environment

z/OS Cloud Broker requires a supported operating environment for deployment.

System hardware requirements:

• x86 or Linux on IBM Z server that runs OpenShift Container Platform
• EC12 or higher IBM Z hardware

System software requirements:

• OpenShift Container Platform 4.12 or higher that runs on x86 or Linux on IBM Z
• z/OS 2.4 or higher

Storage requirements

OpenShift® Container Platform uses the Kubernetes persistent volume (PV) framework to allow cluster administrators to provision persistent storage for a cluster. Developers can use persistent volume claims (PVCs) to request PV resources.

A PVC is required for each instance of z/OS Cloud Broker.

Each z/OS Cloud Broker instance has the following persistent storage requirements:

• Recommended storage size: 5 GiB
• Volume access mode: ReadWriteMany (RWX)

You can use one of the following methods to create and configure PVC for a z/OS Cloud Broker instance:

• Create the PVC during the Creating a z/OS Cloud Broker instance procedure.
• Create a PVC first, and then associate the PVC with a z/OS Cloud Broker instance during the instance creation procedure. See Creating OpenShift Container Platform storage for z/OS Cloud Broker.

OpenShift Container Platform deployment requirements

• Install the Red Hat OpenShift Client command line tool . If you are using a Red Hat OpenShift cluster that was deployed with the IBM Kubernetes Service, follow the instruction to install the Red Hat OpenShift Origin CLI (oc) that includes a matching version of the Kubernetes CLI (kubectl).
