IBM Spectrum Scale Container Storage Interface (CSI) driver
The IBM Spectrum Scale CSI driver enables container orchestrators, such as OpenShift and Kubernetes, to manage the life-cycle of persistent storage. Through this CSI Driver, Kubernetes persistent volumes (PVs) can be provisioned from IBM Spectrum Scale. Thus, containers can be used with stateful microservices, such as database applications (MongoDB, PostgreSQL etc), web servers (nginx, apache), or any number of other containerized applications needing provisioned storage.

Supported Features of the CSI driver(v2.1.0)
Static provisioning: Ability to use existing directories as persistent volumes
Lightweight dynamic provisioning: Ability to create directory-based volumes dynamically
Fileset-based dynamic provisioning: Ability to create fileset-based volumes dynamically
Multiple file systems support: Volumes can be created across multiple file systems
Remote mount support: Volumes can be created on a remotely mounted file system
Operator based deployment: Simplified deployment and management of Driver through Operator

Supported container platforms:
Redhat OpenShift(x86_64) v4.5, v4.6
Vanilla Kubernetes 1.18, 1.19 (x86_64, ppc64le architecture)

Supported IBM storage systems:
IBM Spectrum Scale 5.0.4.1 or Higher

Supported operating systems:
RHEL 7.7, RHEL 7.8, RHEL 7.9 (x86_64, ppc64le architecture)
Ubuntu 20.04 (x86_64) - Need Spectrum Scale 5.1.0 or above

Changes:
Support for Red Hat® OpenShift® 4.6 and Kubernetes 1.19
Support for Ubuntu 20.04
Support for PPC64LE
Support for node Taint and Toleration
Upgraded the ansible-operator version from 0.17.0 to 0.19.4
VolumeHandle format changed to use fileset name instead of fileset ID. This change is backward-compatible and will work with old PVCs with old volume handle format
Added enhancement to dynamically set inode limit for a fileset-based PVC based on the requested PVC size if inode limit is not specified in the StorageClass
Moved to gcr.io from quay.io for sidecar images
Support for Spectrum Scale with sudo wrapper
