System requirements

The system requirements for installing IBM Spectrum Fusion software.

The IBM Spectrum 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 Spectrum Fusion software:
Note: Though there is no minimum number of nodes requirement, the following table provides data based on three control nodes cluster. However, sizing changes based on the number of nodes for components with "Per node" in parenthesis:
Component CPU Memory Storage
IBM Spectrum Fusion Base 12 24 Overall storage is a minimum of 500 MB
Red Hat® OpenShift Data Foundation 30 72 Minimum three storage Nodes

For more information about Red Hat OpenShift Data Foundation, see Important considerations when deploying Red Hat OpenShift Data Foundation 4.10.

Red Hat OpenShift Data Foundation can be deployed on Infra or worker nodes, whereas all other IBM Spectrum Fusion services including Base must be deployed on worker nodes.
Global Data Platform (Per node) 2 8

Backup and restore 4 16 410 GB Minimum

344 GB Minimum, when Red Hat OpenShift Data Foundation is not installed.

System requirements: IBM Spectrum Protect Plus 10.1.12.
Data Cataloging 20 48 1800 GB

The following table lists the component versions:
Component Versions
On-premises VMware Version 6.7 or 7.0
Note: Version 7.0 U3 is required for SNC config.
Red Hat OpenShift Container Platform 4.8 or 4.10
Storage
Red Hat OpenShift Data Foundation 4.10 or OpenShift Container Storage 4.8
OpenShift Container Storage 4.8 is available on OpenShift Container Platform 4.8. For more information about OpenShift Container Storage, see https://access.redhat.com/documentation/en-us/red_hat_openshift_container_storage/4.8.
Note: It is recommended that you use Red Hat OpenShift Data Foundation 4.10.

Red Hat OpenShift Data Foundation 4.10 is available on OpenShift Container Platform 4.10. For more information about Red Hat OpenShift Data Foundation 4.10, see https://access.redhat.com/documentation/en-us/red_hat_openshift_data_foundation/4.10.

Note: For deployment platforms and supported services, see IBM Spectrum Fusion Services support matrix.
IBM Spectrum Scale
Remote mount of IBM Spectrum Scale storage:
  • IBM Spectrum Scale remote storage cluster release 5.1.3 or higher.
  • The IBM Spectrum Fusion cluster accesses the storage owned by an IBM Spectrum Scale storage cluster by using a remote mount.

    The IBM Spectrum Scale file system version of the owning storage cluster cannot be newer than version 30.00.

    To determine the version of your IBM Spectrum Scale cluster, run the mmdiag --version command on the IBM Spectrum Scale cluster. To determine the version of your IBM Spectrum Scale file system, run the mmlsfs all -V command.

    For further information, including installation/upgrade instructions for the remote IBM Spectrum Scale cluster, see IBM Spectrum Scale documentation.
Backup and restore For backup, snapshots can 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. These types of PVCs are automatically filtered and are not displayed in the container inventory in the IBM Spectrum Protect Plus user interface.

Backups are orchestrated via the CSI interface, allowing Spectrum Fusion to backup from a number of CSI storage providers, including OpenShift Data Foundation (ODF) and IBM Spectrum Scale.

IBM Spectrum 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)
  • PersistentVolume (PV) must be created with volumeMode: Filesystem (volumeMode: Block is not supported)
Note: It is also recommended that the the VolumeSnapshotClass deletion policy is configured to delete snapshots after the corresponding VolumeSnapshotContent is deleted (deletionPolicy: Delete).
