Setting up persistent storage

Before you can install IBM® Cloud Pak for Data, you must set up persistent storage on your Red Hat® OpenShift® cluster.

Installation phase: Setting up a client workstation; Collecting required information; Preparing your cluster; Installing the Cloud Pak for Data platform and services
Who needs to complete this task?: A cluster administrator or storage administrator must set up set up persistent storage on the Red Hat OpenShift Container Platform cluster.
When do you need to complete this task?: If you don't have supported storage configured for your cluster, you must complete this task before you can install IBM Cloud Pak for Data.
If you already running supported storage confirm that it is properly configured.

Important: Before you set up persistent storage, ensure that you review the available planning information:

Storage considerations
- Lists the types of storage that are supported by the platform
- Compares the features and requirements for each type of storage
- Identifies the deployment environments that are supported for each type of storage
Storage requirements, which identifies the type of storage each service supports.
Hardware requirements, which specifies the minimum amount of storage that each service requires.

The type of storage that you want to use and complete the appropriate steps to install and configure the storage.

Storage option	Documentation links
OpenShift Data Foundation	Installation To install OpenShift Data Foundation, see the Red Hat OpenShift Data Foundation documentation. Post-installation set up No additional set up is required. You are ready to complete Setting up projects (namespaces) on Red Hat OpenShift Container Platform.
OpenShift Data Foundation as a Service	Installation Contact IBM Support. Post-installation setup Contact IBM Support.
IBM Spectrum® Fusion	Installation To install IBM Spectrum Fusion, see the IBM Spectrum Fusion installation overview in the IBM Spectrum Fusion documentation. Post-installation set up Create the specified storage class with the required parameters. For details, see Setting up IBM Spectrum storage.
IBM Spectrum Scale Container Native (with IBM Spectrum Scale Container Storage Interface)	Installation To install IBM Spectrum Scale and IBM Spectrum Scale Container Storage Interface, see Installing the IBM Spectrum Scale container native operator and cluster (Version 5.1.1.3) in the IBM Spectrum Scale Container Native documentation. Post-installation set up Create the specified storage class with the required parameters. For details, see Setting up IBM Spectrum Scale Container Native storage.
Portworx	Installation To install Portworx Enterprise, see Install Portworx on OpenShift in the Portworx documentation. Post-installation set up Create the specified storage classes with the required parameters. For details, see Creating Portworx storage classes.
NFS	Installation Refer to the installation documentation for your NFS storage provider. Post-installation set up At a minimum, you must set up dynamic storage provisioning. Depending on the services you plan to install, you might need to configure your NFS server. For details, see Setting up NFS storage.
Amazon Elastic Block Store (EBS)	Installation EBS is provisioned by default when you install a Red Hat OpenShift Container Platform cluster on AWS. Post-installation setup No additional set up is required. You are ready to complete Setting up projects (namespaces) on Red Hat OpenShift Container Platform.
Amazon Elastic File System (EFS)	Installation Install EFS from the AWS Console. It is recommended that you create a regional file system. Post-installation setup You must set up dynamic storage provisioning. For details, see Setting up Amazon Elastic File System.
IBM Cloud Block Storage	Installation IBM Cloud Block Storage is provisioned by default when you install a Red Hat OpenShift Container Platform cluster on IBM Cloud. Post-installation setup No additional set up is required. You are ready to complete Setting up projects (namespaces) on Red Hat OpenShift Container Platform.
IBM Cloud File Storage	Installation When you configure your Red Hat OpenShift cluster on IBM Cloud, ensure that you select one of the following IBM Cloud File Storage storage classes: `ibmc-file-gold-gid` `ibm-file-custom-gold-gid` Post-installation set up Depending on the services you plan to install, you might need to configure your IBM Cloud File Storage. For details, see Setting up IBM Cloud File Storage. If you are running a production workload on your cluster, it is recommended that you adjust your I/O and performance and storage size: The default I/O settings are typically lower than the minimums specified in the Disk requirements section. To improve the I/O performance for production environments, you must adjust the I/O settings. Contact IBM Software Support for guidance on how to adjust the settings according to Changing the size and IOPS of your existing storage device. Storage is not automatically expanded and is created in smaller chunks. Increasing the size of the volumes improves I/O performance for production environments. Contact IBM Software Support for assistance.
