Helm Chart

GA v2.1.0

IBM Storage Enabler for Containers allows IBM storage systems to be used as persistent volumes for stateful applications running in Kubernetes clusters. The IBM official solution for Kubernetes, based on the Ubiquity project, is referred to as IBM Storage Enabler for Containers. The solution supports both IBM block- and file-based storage systems.

• IBM block storage is supported via IBM Spectrum Connect. Enabler for Containers communicates with the IBM storage systems through Spectrum Connect. Spectrum Connect creates a storage profile (for example, gold, silver or bronze) and makes it available for Kubernetes.
• IBM Spectrum Scale is supported via a direct communication link between Enabler for Containers and Spectrum Scale REST API v2.

You can download the installation package for and its documentation from IBM Fix Central.
