The system requirements for installing IBM Storage Fusion software.
The
IBM Storage Fusion operators and your workloads run
on
OpenShift® Container Platform that in turn are installed on amd64:
64-bit Intel, AMD x86, or
Linux on IBM zSystems hardware
architecture. The following table lists the system requirements for
IBM Storage Fusion software:
Note: Though there is no minimum
number of nodes requirement, the following table provides data based on three control nodes and
three compute nodes cluster. However, sizing changes based on the number of nodes for components
with "Per node".
IBM Fusion Data Foundation can be deployed
on Infra or worker nodes, whereas all other IBM Storage Fusion services including Base must be deployed on worker nodes.

Note:
IBM Fusion Data Foundation 4.14 is supported on IBM Storage Fusion 2.7.1. IBM Fusion Data Foundation 4.14 is available on OpenShift Container Platform 4.14.
- IBM Storage Scale
- Remote mount of IBM Storage Scale storage:
Note:
IBM Storage Fusion 2.7.1 or higher supports IBM Storage Scale 5.1.9. IBM Storage Fusion 2.7 supports IBM Spectrum Scale 5.1.7.
- IBM Storage Scale remote storage cluster
release 5.1.3 or higher.
- The IBM Storage Fusion cluster accesses the storage
owned by an IBM Storage Scale storage cluster by
using a remote mount.
The
IBM Storage Scale file system version of the
owning storage cluster cannot be newer than version 33.00.
For more information, see Software requirements.
To determine the version of your IBM Storage Scale cluster, run the mmdiag
--version command on the IBM Storage Scale cluster. To determine the version
of your IBM Storage Scale file system, run the
mmlsfs all -V
command.For
further information, including installation/upgrade instructions for the remote IBM Storage Scale cluster, see IBM Storage Scale
documentation.

Backup & Restore |
IBM Storage Fusion supports backup and recovery
operations on Red Hat
OpenShift Container Platform environment on AMD64 with any storage
provider that implemented the Container Storage Interface (CSI) driver and meets the following prerequisites:
- The Container Storage Interface driver must be v1 or higher (no support for alpha or
beta versions)
- The Container Storage Interface driver must support Volume Snapshot and Restore.
- StorageClass must be created with
volumeBindingMode: Immediate
(volumeBindingMode: WaitForFirstConsumer is not supported) and
allowVolumeExpansion: true .
- PersistentVolume (PV) must be created with
volumeMode: Filesystem
(volumeMode: Block is not supported )
Note: It is also recommended that the VolumeSnapshotClass deletion policy is
configured to delete snapshots after the corresponding VolumeSnapshotContent is
deleted (deletionPolicy: Delete ).
Note: For backups of PVCs provisioned on
IBM Storage Scale, snapshots are be created only
from independent fileset-based persistent volume claims (PVCs). PVCs that are based on lightweight
directories and dependent file sets are not supported.
