Hardware requirements for installation
To install IBM Fusion Data Foundation on IBM Z and IBM® LinuxONE, the following hardware requirements must be met:
- An OpenShift Container Platform cluster must be installed. This implies that requirements for a
Red Hat OpenShift installation must also be met.
- For a minimal deployment on IBM Z hardware, approximately 6 IFLs (physical cores referred to as Integrated Facility for Linux) are required.
- For each Red Hat OpenShift control node, 16 GB of Memory and 120 GB of storage are required.
- For Red Hat OpenShift itself, a minimum of 2 compute nodes is required, each consuming 8 GB of memory and 120 GB of storage. But if IBM Fusion Data Foundation Local Storage O is installed afterward, a minimum of 3 compute nodes is necessary instead. Optionally, infrastructure nodes can be installed.
- IBM Fusion Data Foundation needs to deploy 3 storage nodes in the Red Hat OpenShift cluster.
Storage nodes can be deployed on either 3 compute or 3 infrastructure nodes in the same Red Hat
OpenShift cluster.
- IBM Fusion Data Foundation adds at least the need for one more IFL to the entire deployment. Depending on the workload up to 4 IFLs can become necessary.
- Each storage node requires another 64 GB Memory and at least 512 GB of storage.
- For IBM zCX, similar hardware needs to be applied. zCX leverages zIIPs instead of IFLs as processing units.
Note:
- IBM Fusion Data Foundation storage nodes can be either installed on compute nodes or on infrastructure nodes within the same cluster. When installing on infrastructure nodes, the application workload on the compute nodes can scale independently of the storage nodes. When installing on compute nodes, the application and the available storage scale together, and the management is a bit easier.
- The described environment addresses a minimal hardware setup, which is limited in terms of capacity and performance. For CPU intense and network intense workload, the hardware needs increase.
- Depending on the subscription, IBM Fusion Data Foundation can be deployed via the Red Hat Operator Hub (using the branding Red Hat OpenShift Data Foundation) or by installing via IBM Fusion from IBM (using the new branding IBM Fusion Data Foundation).
