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:
Required storage | Details |
---|---|
Container image 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. For details, see Mirroring images to your container registry. If you use a private container registry, you must have sufficient space for the Cloud Pak for Data control plane images and the images for the services that you plan to install.
|
Local storage for container images | Each node on your cluster must have local storage for the container images that are running
on that node.
|
Persistent storage for services | The Cloud Pak for Data control plane and services store
data in persistent storage.
|
Cloud Pak for Data control plane persistent storage requirements
The Cloud Pak for Data control plane supports all of the shared persistent storage types that are supported by the platform. When you install the control plane you must specify the appropriate storage class:
Storage type | Storage classes | Access mode |
---|---|---|
OpenShift Container Storage |
|
For details, see the OpenShift Container Storage documentation. |
IBM Spectrum storage:
|
ibm-spectrum-scale-sc or an equivalent
storage class. |
ReadWriteMany (RWX) For details, see the IBM Spectrum Scale Container Storage Interface Driver documentation. |
NFS | managed-nfs-storage or an equivalent storage class. |
Specify a storage class that supports ReadWriteMany (RWX) access. |
Portworx |
|
For details, see Creating Portworx storage classes. |
IBM Cloud File Storage (IBM Cloud deployments only.) |
|
