Requirements

This section covers hardware and software requirements for an IBM Cloud Pak for Data 3.0.1 installation.

IBM Cloud Pak for Data 3.0.1 requires Red Hat OpenShift Container Platform (OCP) 3.11 or 4.x to be installed as prerequisites. The installation of OpenShift Container Platform is covered in this section of the Playbook.

Minimum Hardware Requirements

The following minimum recommendations are for demos and proof-of-concept with Cloud Pak for Data. The time on all of the nodes must be synchronized within 500ms.

Minimum requirements for Red Hat® OpenShift Container Platform Version 3.11.188 or later fixes:

Node roleHardwareNumber of nodesCPURAMRoot disk
Master + infrax86-6418 cores32 GB120 GB
Worker/computex86-642 (for NFS) or 3 (for PX)16 cores64 GB120 GB

Minimum requirements for Red Hat OpenShift Container Platform Version 4.3.18 or later fixes:

Node roleHardwareNumber of nodesCPURAMRoot disk
Master + infrax86-64, ppc64le3 (for HA)4 cores16 GB120 GB
Worker/computex86-64, ppc64le316 cores64 GB120 GB

Additional cores and nodes should be added depending on the services you need (see System requirements for services for details).

Production level hardware requirements

The following minimum recommendations are for small production usage (or proof-of-concept for larger workloads) with Cloud Pak for Data. High availability is always recommended. The time on all of the nodes must be synchronized within 500ms.

Node roleHardwareNumber of nodesCPURAMRoot disk
Master + infrax86-64, ppc64le3 (for HA)8 cores32 GB120 GB
Worker/computex86-64, ppc64le3+16 cores64 GB (128 GB recommended)120 GB
Load balancerx86-64, ppc64le18 cores8 GB200 GB

Storage requirements

An additional 200 GB of free space in the root file system on all of the nodes. See Storage considerations for the supported storage types and requirements.

Cloud Pak for Data with all services installed can use up to 700 GB of storage space, leaving up to 300 GB of storage space available for user data. You can add additional capacity depending on your user data volume requirements.

Software requirements

  • A Red Hat Enterprise Linux cluster with Red Hat OpenShift installed on it, either:

    • Red Hat OpenShift Container Platform Version 3.11.188 or later fixes for on-premises.
    • Red Hat OpenShift Container Platform Version 4.3.18 or later fixes for on-premises.
    • IBM Cloud, Microsoft Azure, Amazon Web Services, or Google Cloud Platform.

Important: Cloud Pak for Data includes entitlement to both the Red Hat OpenShift Container Platform and Red Hat Enterprise Linux. You can download Red Hat OpenShift either from IBM Passport Advantage® or directly from the Red Hat Customer Portal.

  • The OpenShift cluster should include:
Container RuntimeOpenShift VersionStorage TypeStorage Requirement
CRI-O version 1.13 or later4.x, 3.11NFS, IBM Cloud FS, Portworx, OCS200 GB
Docker with the overlay2 driver3.11NFS200 GB

Attention: For the overlay2 driver, you must enable d_type=true and ftype=1 or else the installation will fail. See Use the OverlayFS storage driver for details. After you install OpenShift, enter docker info and verify that Storage Driver: overlay2 and Supports d_type: true.

  • A registry to store images on, with a minimum of 300 GB of storage space. The registry must be accessible from all of the nodes in the cluster. Additionally, all of the nodes must have permission to push to and pull from the registry. See Setting up your registry server for details.

  • A Linux or Mac OS client workstation to perform the installation from. The workstation does not have to be part of the OpenShift cluster, but must be able to oc login to the cluster.

Security requirements

You must have a cluster-admin account to set up the environment for Cloud Pak for Data. The cluster-admin user must grant the cpd-admin-role to the project administration user that will install Cloud Pak for Data in the corresponding OpenShift project.

Supported web browsers

  • Mozilla Firefox (recommended) - Version 54 and higher
  • Google Chrome - Version 60 and higher
