Setting up shared persistent storage

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

Important: Before you set up your 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
    • Identifies which type of storage are supported by each service
    • Specifies the minimum amount of storage that each service requires.

Select your storage type and complete the steps to set up storage.

Storage type What to do
Red Hat OpenShift Container Storage
Installation
To install OpenShift Container Storage, see the Red Hat OpenShift Container Storage documentation.
Post-installation set up
No additional set up is required.
IBM Spectrum® storage
Installation
IBM Spectrum Fusion
To install IBM Spectrum Fusion, see IBM Spectrum Fusion installation overview in the IBM Spectrum Fusion documentation.
IBM Spectrum Scale Container Storage Interface
For IBM Spectrum Scale and IBM Spectrum Scale Container Storage Interface, see Installing the IBM Spectrum Scale container native operator and cluster in the IBM Spectrum Scale Container Native documentation.
Post-installation set up
Create the IBM Spectrum Scale storage class with parameters. For details, see Setting up IBM Spectrum storage.
Portworx
Installation

To install Portworx Enterprise, see Install Portworx on OpenShift

Post-installation set up
You must configure the required storage classes. 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.
IBM Cloud File Storage
Installation
When you configure your Red Hat OpenShift cluster, 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.
