vSphere Storage Interface (CSI)
The main goal of vSphere Container Storage Interface (CSI) is to expose vSphere storage and features to Kubernetes users. It offers an in-tree volume driver that has been actively used on various Kubernetes platforms by service providers, including on-prem. Cloud Native Storage (CNS) is a result of evolution and productization of vSphere Storage for Kubernetes and is also enterprise ready.
vSphere CSI Driver Components
The vSphere CSI driver includes the following components:
- vSphere CSI Controller
- vSphere CSI Node
- Syncer
