IBM Storage Scale Container Storage Interface (CSI) driver
The IBM Storage 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 Storage 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(v2.11.0)

  • 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.
  • Shallow copy volume support : Ability to create new persistent volume (ROX) from volume snapshot
  • 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.
  • Support for the multiple GUIs configuration (GUI HA) for a CSI driver on Vanilla Kubernetes: Ability to configure multiple GUIs in case of GUI is installed on multiple nodes of a storage cluster.
  • Support to configure resource limits of IBM Storage Scale Container Storage Interface driver

Supported container platforms:
Redhat OpenShift 4.13, 4.14 and 4.15 (x86_64 architecture) through Red Hat Enterprise Linux (RHEL) 7 or RHEL 8 worker nodes
