Container Storage Modules Documentation

What is Container Storage Modules?

Container Storage Modules enhances the Container Storage Interface (CSI) to provide advanced enterprise storage features for Kubernetes clusters. It includes software modules that extend beyond CSI, offering enterprise storage capabilities to Kubernetes users. Dell’s primary storage options (PowerStore, PowerScale, PowerFlex, PowerMax, and Unity XT) can use these modules to simplify management. This allows developers to easily access and automate tasks like Authorization, Replication, Snapshotting, Resiliency, Observability, and Application Mobility.

Authorization provides storage and Kubernetes administrators the ability to apply RBAC for Dell CSI Drivers. It does this by deploying a proxy between the CSI driver and the storage system to enforce role-based access and usage rules.

Replication project aims to bring Replication & Disaster Recovery capabilities of Dell Storage Arrays to Kubernetes clusters. It helps you replicate groups of volumes and can provide you a way to restart applications in case of both planned and unplanned migration.

Resiliency is designed to make Kubernetes Applications, including those that utilize persistent storage, more resilient to various failures.

Observability provides visibility on the capacity of the volumes/file shares that is being managed with Container Storage Modules. It includes CSI (Container Storage Interface) drivers along with their performance in terms of bandwidth, IOPS, and response time.

Application Mobility provide Kubernetes administrators the ability to clone their stateful application workloads and application data to other clusters in the cloud.
