Data Foundation
Install Fusion Data Foundation in local, dynamic, external, or consumer modes.
Before you begin
- If you already have an installation of IBM Fusion Data Foundation cluster or Red Hat® OpenShift® Data Foundation cluster, then the IBM Storage Fusion UI automatically discovers it. However, in the Data Foundation page, you can only view the Usable capacity, Health, and information about the storage nodes.
- If you have a Rook-Ceph operator, then contact IBM Support for the expected behavior.
- You can use a maximum of nine storage devices per node. The high number of
storage devices leads to a higher recovery time during the loss of a node. This recommendation
ensures that nodes stay below the cloud provider dynamic storage device attachment limits, and
limits the recovery time after node failure with local storage devices.
It is recommended to add nodes in the multiple of three, each of them in different failure domains.
For deployments having three failure domains, you can scale up the storage by adding disks in the multiple of three, with the same number of disks coming from nodes in each of the failure domains.
-
Run following steps to ensure that there is no previously installed IBM Fusion Data Foundation, Red Hat OpenShift Data Foundation, OpenShift Container Storage, or Rook-Ceph in this OpenShift cluster before you enable the IBM Fusion Data Foundation service:
- Verify that the namespace
openshift-storage
does not exist. - Run the following command to confirm that no resources exist:
oc get storagecluster -A; oc get cephcluster -A
- Run the following command to confirm that none of the nodes have a IBM Fusion Data Foundation storage label or Red Hat OpenShift Data Foundation storage label:
oc get node -l cluster.ocs.openshift.io/openshift-storage=
- Verify that the namespace
-
- Infrastructure nodes
- Ensure that the following prerequisites are met:
- For infrastructure requirements, see Infrastructure requirements of IBM Fusion Data Foundation.
- For IBM Fusion Data Foundation resource requirements, see ODF sizer tool. For common IBM Fusion Data Foundation components per instance requirements of CPU and Memory, see Resource requirements.
- If you want to deploy IBM Fusion Data Foundation in an
Infra node, make sure the worker node label
exists.
oc get node -l "node-role.kubernetes.io/worker="
- Ensure that there are no taints in the infra or compute nodes that are used as storage nodes.
About this task
- Both Data Foundation service and
Global Data Platform service can coexist during the following
scenarios:
- Deploy Data Foundation service without
dedicated
mode. - Deploy Data Foundation in
dedicated
mode first, and then deploy Global Data Platform service.
- Deploy Data Foundation service without
- For Red Hat OpenShift Data Foundation deployed outside of IBM Storage Fusion, you cannot add nodes or capacity from IBM Storage Fusion. See Red Hat OpenShift Data Foundation Scaling storage document.
- For consumer mode cluster with Fusion Data Foundation, you do not install IBM Storage Fusion spoke cluster or Fusion Data Foundation from the user interface. These installations are automatically run from the IBM Storage Fusion HCI System hub cluster.
- Data Foundation service
supports four storage types: Local, Dynamic, External, and consumer. Only one device type can be
used for Data Foundation service in an OpenShift Container Platform. The following table shows supported
platforms and which device types are supported in each platform.

What to do next
Optionally, you also setup encryption to use an external Key Management System. For the procedure to set up encryption, see Preparing to connect to an external KMS server in IBM Fusion Data Foundation.
