Remote physical location requirements

A remote physical location is processing infrastructure on a remote cluster. When you set up a remote physical location, you install IBM Cloud Pak for Data agents on a remote cluster.

If you plan to use remote physical locations to expand your IBM Cloud Pak for Data deployment to remote clusters, you must ensure that the cluster where you plan to install the Cloud Pak for Data agents has the required hardware, software, and storage.

Prerequisites

Before you create remote physical locations, you must have an instance of IBM Cloud Pak for Data that you want to expand. You cannot run the commands required to create a remote physical location unless you have an existing Cloud Pak for Data deployment.

This instance is called the primary instance of Cloud Pak for Data or the hub.

Software

You must have the following software on the cluster where you plan create a remote physical location:

Red Hat® OpenShift® Container Platform

For entitlement information see Licenses and entitlements.

Cloud Pak for Data supports the following versions of Red Hat OpenShift Container Platform. (Cloud Pak for Data supports the same operating system requirements as Red Hat OpenShift Container Platform.)

Important: Cloud Pak for Data supports only the specified releases of Red Hat OpenShift Container Platform.

Different versions of Cloud Pak for Data support different versions of Red Hat OpenShift Container Platform.

Restriction: Do not install the KubeVirt HyperConverged Cluster Operator from the Community Operator catalog source on the cluster.

Hardware

Only x86-64 hardware is supported.

You can use a multi-node cluster or a single node OpenShift ( SNO) cluster.

Requirements for shared cluster components

Software vCPU Memory Storage Notes
IBM Certificate manager 1.6 vCPU 1.94 GB RAM This information is not currently available. A certificate manager is required.

Operator pods:
0.1 vCPU

Instance pods:
  • Small: 7 vCPU
  • Medium: 14 vCPU
  • Large: 28 vCPU
Operator pods:
0.256 GB RAM

Instance pods:
  • Small: 28 GB RAM
  • Medium: 52 GB RAM
  • Large: 100 GB RAM
Persistent storage:
10 GB per instance  (assuming defaults)

Ephemeral storage:
10 GB per instance

Image storage:

The resources required depend on the following factors:
  • The number of instances you plan to provision on the remote physical location.
  • The size of each instance on the physical location

Storage

The remote physical location must use the same persistent storage as the primary instance of Cloud Pak for Data. Ensure that the storage class names are the same on the primary instance and on the remote physical location.
