Kubernetes Storage Evolution: Enabling High Performance Distributed Datastores
summary
Kubernetes adds reproducible local disk support by extending PV/PVCs so admins register local PersistentVolumes with nodeAffinity and the scheduler binds volumes during pod placement (demo uses three replicas). 1.7 introduces the local PV type, 1.9 moves binding into scheduling and exposes volumeMode=Block for raw devices (static provisioning only today, Fibre Channel plugin lands in 1.9). Dynamic provisioning and CSI integration remain work in progress.
