-
The Dell Container Storage Interface (CSI) provides storage enablement as part of the Dell Container Storage Modules (CSM). CSM extends enterprise storage capabilities to Kubernetes for cloud-native stateful applications. The CSI driver for PowerScale provides an interface between a CSI-enabled Container Orchestrator (CO) and a PowerScale cluster.
CSI allows administrators to replicate groups of volumes using OneFS SyncIQ and provides an option to restart applications in case of planned and unplanned migrations, as shown in Figure 26.
