Storage considerations

To install IBM Cloud Pak® for Data, you must have a supported persistent storage solution that is accessible to your Red Hat® OpenShift® cluster.

Review the following sections to determine what storage is right for you:

What storage options are supported for the platform?
What storage options are supported on my deployment environment?
What storage options are supported on the version of Red Hat OpenShift Container Platform that I am running?
What storage options are supported on my hardware?

What storage options are supported for the platform?

Cloud Pak for Data supports and is optimized for several types of persistent storage.

Cloud Pak for Data uses dynamic storage provisioning. A Red Hat OpenShift cluster administrator must properly configure storage before Cloud Pak for Data is installed.

Important: It is your responsibility to review the documentation for the storage that you plan to use. Ensure that you understand any limitations that are associated with the storage.

As you plan your installation, remember that not all services support all types of storage. For complete information on the storage that each service supports, see Storage requirements. If the services that you want to install don't support the same type of storage, you can have a mixture of different storage types on your cluster. However, it is recommended to use one type of storage, if possible.

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.

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.

Note: The preceding storage options have been evaluated by IBM. However, you should run the Cloud Pak for Data storage validation tool on your Red Hat OpenShift cluster to:

Evaluate whether the storage on your cluster is sufficient for use with Cloud Pak for Data.
Assess storage provided by other vendors. This tool does not guarantee support for other types of storage. You can use other storage environments at your own risk.

What storage options are supported on my deployment environment?

If Cloud Pak for Data supports a storage option, you can install Cloud Pak for Data with that storage if it is supported on your deployment option. Ensure that you select a storage option that:

Works on your chosen deployment environment.
Some storage options are supported only on a specific deployment environment.

For clusters hosted on third-party infrastructure, such as IBM Cloud or Amazon Web Services, it is recommended that you use storage that is native to the infrastructure or well integrated with the infrastructure, if possible.
Supports the services that you plan to install.
Some services support a subset of the storage options that are supported by the platform. For details, see Storage requirements.

Has sufficient I/O performance.

For information on how to test I/O performance, see Disk requirements.

Encryption of data at rest

Storage option	Details
OpenShift Data Foundation	Supported. OpenShift Data Foundation uses Linux Unified Key System (LUKS) version 2 based encryption with a key size of 512 bits and the aes-xts-plain64 cipher. You must enable encryption for your whole cluster during cluster deployment to ensure encryption of data at rest. Encryption is disabled by default. Working with encrypted data incurs a small performance penalty. For details, see Security considerations in the OpenShift Data Foundation documentation: Version 4.10 Version 4.12 Restriction: If you are using OpenShift Data Foundation Essentials, you can use only keys that are managed on the cluster, you cannot use an external key management system (KMS). Support for FIPS cryptography By storing all data in volumes that use RHEL-provided disk encryption and enabling FIPS mode for your cluster, both data at rest and data in motion, or network data, are protected by FIPS Validated Modules in Process encryption. You can configure your cluster to encrypt the root file system of each node. For details, see FIPS 140-2 in the OpenShift Data Foundation documentation: Version 4.10 Version 4.12 If you have OpenShift Data Foundation Advanced, you can also encrypt persistent volume claims (PVCs) in addition to enabling encryption for the whole cluster. You can enable PVC encryption for storage that is created by the `ocs-storagecluster-ceph-rbd` storage class.
IBM Storage Fusion Data Foundation	Supported. IBM Storage Fusion Data Foundation uses Linux Unified Key System (LUKS) version 2 based encryption with a key size of 512 bits and the aes-xts-plain64 cipher.

Working with encrypted data incurs a small performance penalty. For details, see Security considerations in the IBM Storage Fusion documentation: Version 2.5 Support for FIPS cryptography By storing all data in volumes that use RHEL-provided disk encryption and enabling FIPS mode for your cluster, both data at rest and data in motion, or network data, are protected by FIPS Validated Modules in Process encryption.
