System requirements for required components

Required components provide required underlying functionality for IBM® Cloud Pak for Data services. Required cluster components describes when and how these components are installed. Ensure that you have sufficient resources to install the appropriate components on your cluster.

Required component support information

The information is provided in the following sections:

Version support

Use this table to determine which versions of a component are supported on the version of Cloud Pak for Data that you are running.

Hardware requirements

Use this table to determine whether you have the minimum required resources to install the component on your Cloud Pak for Data cluster.

Important: The information in this table represents the minimum resources you need to successfully install the component. You might need additional resources to support your specific workload. Work with your IBM Sales representative to generate more accurate calculations based on your expected workload.

Keep the following information in mind as you review the hardware requirements:

  • Unless explicitly stated, the component can be scheduled across existing worker nodes.
  • If a component requires dedicated nodes, the documentation for the component describes how to prevent other components or services from running on those nodes.
Service x86-64 POWER® Z vCPU Memory Storage requirements Notes
Common core services   11 vCPU 17.8 GB RAM 500 GB
Supported storage types:
  • NFS
  • OpenShift Container Storage
    Required storage classes:
    • ocs-storagecluster-ceph-rbd
  • Portworx
    Required storage classes:
    • portworx-couchdb-sc
    • portworx-elastic-sc
    • portworx-gp3-sc
  • IBM Cloud File Storage
    Supported storage classes:
    • ibmc-file-gold-gid
    • ibm-file-custom-gold-gid
If this component is needed, it is installed once in each project where Cloud Pak for Data is installed.

The component is a dependency for multiple services. The first service that specifies the common core services as a dependency installs the component. The preceding resources are required in addition to the resources required for the service installation.

Scheduling service   4 vCPU 10 GB RAM 10 GB
Supported storage types:
  • NFS
  • OpenShift Container Storage
    Required storage classes:
    • ocs-storagecluster-cephfs
  • PortworxRequired storage classes:
    • portworx-shared-gp3
This component is installed once and is used by any instances of Cloud Pak for Data on the cluster.
