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(v2.8.0)
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
Volume snapshot support: Ability to take a point-in-time snapshot of volume and creating new volume from existing snapshot
Volume cloning support: To duplicate an existing persistent volume at a particular point-in-time.
Volume expansion support: Ability to expand a dynamically provisioned volume.
Compression support: Ability to enable compression for dynamically provisioned volumes.
Tiering support: Ability to enable tiering for dynamically provisioned volumes.
Consistency Group support: Ability to have group of volumes for application groups.
Volume stat support for fileset based volumes: Ability to show available and used capacity of fileset based volumes.

Supported container platforms:
Redhat OpenShift v4.9, v4.10, v4.11
Vanilla Kubernetes 1.23, 1.24, 1.25
