IBM Spectrum Fusion software is a container-native platform designed for Kubernetes applications running on Red Hat OpenShift Container Platform (OCP).
IBM Spectrum Fusion software uses OpenShift Data Foundation (ODF) for data services, and IBM Spectrum Protect Plus data protection software. Red Hat developed OpenShift Data Foundation (ODF) as part of its OpenShift container management platform. IBM acquired ODF with Red Hat’s other storage technology – including open-source Ceph – in 2022.
IBM sells two versions of Spectrum Fusion. IBM Spectrum Fusion HCI ships as a turnkey appliance running on x86 servers, and uses IBM Spectrum Scale Erasure Coding Edition (ECE) scale-out file system for data services.
The IBM Spectrum Fusion software-defined storage (SDS) supports IBM Power servers or a range of x86 hardware appliances from IBM partners or IBM Power 9 servers. Both Spectrum Fusion versions incorporate IBM Spectrum Protect Plus for data protection, and are designed for the Red Hat OpenShift container platform. The software-defined storage version is a bare metal deployment of Red Hat OCP that runs on VMware.
There are a few other differences between Spectrum Fusion HCI and Spectrum Fusion software-defined storage besides the turnkey appliance. Spectrum Fusion HCI requires a six-node minimum (three control and three compute nodes) while Spectrum Fusion SDS starts with three nodes. Spectrum Fusion SDS also supports IBM Spectrum Discover metadata management software for unstructured data; Spectrum Fusion HCI does not support Spectrum Discover.
