Storage requirements

Before you install IBM Cloud Pak® for Data, review the storage requirements for the control plane, the shared cluster components, and the services that you plan to install.

Cloud Pak for Data platform storage requirements

A Cloud Pak for Data deployment requires several types of storage:

Storage for images in the private container registry
Depending on your environment, you might need to store images in a private container registry rather than pulling them directly from the IBM Entitled Registry.

If you use a private container registry, you must have sufficient space for the Cloud Pak for Data components that you plan to install.

Sizing
A minimum of 300 GB of storage space in the private container registry.
Best practices:
Local storage for container images
Each node on your cluster must have local storage for the container images that are running on that node.
Storage location
The container images are stored in the root file system on the nodes.

On Red Hat® OpenShift® Container Platform, local copies of the images are stored in /var/lib/containers. For details, see Data storage management in the Red Hat OpenShift Container Platform documentation:

Sizing
A minimum of 300 GB of storage space per node.
Persistent storage
Cloud Pak for Data supports and is optimized for several types of persistent storage:
Storage option Version Notes
OpenShift Data Foundation
  • Version 4.10 or later fixes
  • Version 4.12 or later fixes
 Available in Red Hat OpenShift Platform Plus.

Ensure that you install a version of OpenShift Data Foundation that is compatible with the version of Red Hat OpenShift Container Platform that you are running. For details, see https://access.redhat.com/articles/4731161.
IBM Storage Fusion Data Foundation
  • Version 2.5.2 or later fixes
  • Version 2.6.0 or later fixes (Recommended)
 Available in IBM Storage Fusion.

Ensure that you install a version of IBM Storage Fusion Data Foundation that is compatible with the version of Red Hat OpenShift Container Platform that you are running.

If you want to use IBM Storage Fusion for backup and recovery, you must use Version 2.6.

If you are upgrading to IBM Cloud Pak for Data Version 4.7, and you want to use IBM Storage Fusion, Version 2.6.0, upgrade your storage after you upgrade IBM Cloud Pak for Data.
IBM Storage Fusion Global Data Platform
  • Version 2.4.0 or later fixes
  • Version 2.5.2 or later fixes
  • Version 2.6.0 or later fixes (Recommended)
 Available in IBM Storage Fusion.

If you want to use IBM Storage Fusion for backup and recovery, you must use Version 2.6.

If you are upgrading to IBM Cloud Pak for Data Version 4.7, and you want to use IBM Storage Fusion, Version 2.6.0, upgrade your storage after you upgrade IBM Cloud Pak for Data.
IBM Storage Scale Container Native (with IBM Storage Scale Container Storage Interface) Version 5.1.5 or later fixes

CSI Version 2.6.x or later fixes

 Available in the following storage:
  • IBM Storage Fusion
  • IBM Storage Suite for IBM Cloud® Paks
Portworx
  • Version 2.9.1.3 or later fixes
  • Version 2.13.3 or later fixes
 If you are running Red Hat OpenShift Container Platform Version 4.12, you must use Portworx Version 2.13.3 or later.
NFS Version 3 or 4
Version 3 is recommended if you are using any of the following services:
  • Db2®
  • Db2 Big SQL
  • Db2 Warehouse
  • Watson Knowledge Catalog
  • Watson Query

If you use Version 4, ensure that your storage class uses NFS Version 3 as the mount option. For details, see Setting up dynamic provisioning.
Amazon Elastic Block Store (EBS) Not applicable In addition to EBS storage, your environment must also include EFS storage.
Amazon Elastic File System (EFS) Not applicable It is recommended that you use both EBS and EFS storage.
NetApp Trident Version 22.4.0 or later fixes This information applies to both self-managed and managed NetApp Trident.
When you plan your environment, ensure that you review the storage types that are supported by the components that you plan to install:
Tip: The preceding storage options have been evaluated by IBM. You can run the Cloud Pak for Data storage validation tool to assess storage that is provided by other vendors. However, this tool does not guarantee support for other types of storage. You can use other storage environments at your own risk.
Sizing
The minimum amount of storage depends on the type of storage that you plan to use. For details, see the Resource requirements section under Storage comparison.

As a general rule, Cloud Pak for Data with all services installed can use up to 700 GB of storage space. Review the Storage comparison to ensure that you have sufficient storage space available for user data based on the type of storage that you select. You can add additional capacity depending on your user data volume requirements.

Cloud Pak for Data control plane persistent storage requirements

The Cloud Pak for Data control plane supports all of the persistent storage options that are supported by the platform.

The control plane uses ReadWriteOnce (RWO) storage, which is specified through the --block_storage_class option. However, the installation and upgrade commands include both of the following options:
  • --block_storage_class
  • --file_storage_class
The following table lists the recommended storage classes. If your cluster uses different storage class names, ensure that you specify equivalent storage classes.

  • The --block_storage_class option should point to block storage or to a file storage class that supports ReadWriteOnce (RWO) access.

  • The --file_storage_class option should point to a file storage class that supports ReadWriteMany (RWX) access.

Storage option Recommended block storage class Recommended file storage class Notes
OpenShift Data Foundation ocs-storagecluster-ceph-rbd ocs-storagecluster-cephfs The default storage class names are different if you use external mode.
IBM Storage Fusion Data Foundation ocs-storagecluster-ceph-rbd ocs-storagecluster-cephfs The default storage class names are different if you use external mode.
IBM Storage Fusion Global Data Platform ibm-spectrum-scale-sc ibm-spectrum-scale-sc IBM Storage Fusion Global Data Platform supports both ReadWriteMany (RWX access) and ReadWriteOnce (RWO access) with the same storage class.

Specify the same storage class for block storage and file storage.
IBM Storage Scale Container Native ibm-spectrum-scale-sc ibm-spectrum-scale-sc IBM Storage Scale Container Native supports both ReadWriteMany (RWX access) and ReadWriteOnce (RWO access) with the same storage class.

Specify the same storage class for block storage and file storage.
Portworx portworx-metastoredb-sc portworx-rwx-gp3-sc For more information about the recommended Portworx storage classes, see Creating Portworx storage classes.
NFS managed-nfs-storage managed-nfs-storage NFS supports both ReadWriteMany (RWX access) and ReadWriteOnce (RWO access) with the same storage class.

Specify the same storage class for block storage and file storage.
Amazon Elastic Block Store gp2-csi or gp3-csi Not applicable. Your environment must include Amazon Elastic File System storage in addition to Amazon Elastic Block Store.
Amazon Elastic File System Not applicable. efs-nfs-client It is strongly recommended that you use both Amazon Elastic Block Store storage and Amazon Elastic File System storage.
  • The Cloud Pak for Data control plane is more performant when you provide both file and block storage.
  • You can install services that require both file and block storage.

If you use only Amazon Elastic File System, specify efs-nfs-client for both file and block storage.
NetApp Trident ontap-nas ontap-nas NetApp Trident supports both ReadWriteMany (RWX access) and ReadWriteOnce (RWO access) with the same storage class.

Specify the same storage class for block storage and file storage.
