IBM Spectrum Scale container native

IBM Spectrum Scale container native allows the deployment of the cluster file system in a Red Hat® OpenShift® cluster. Using a remote mount attached file system, the container native deployment provides a persistent data store to be accessed by the applications through the IBM Spectrum Scale CSI driver by using Persistent Volumes (PVs). For more information, see IBM Spectrum Scale Container Storage Interface Driver in IBM Spectrum Scale CSI documentation.

Supported container platforms

Red Hat OpenShift v4.10, v4.11, v4.12

Supported operating systems

Red Hat CoreOS

Supported architectures

x86_64, ppc64le, s390x
