Raw Block Volumes

This page describes support for raw block volumes by the Container Storage Interface (CSI) Storage Plugin.

The HPE implementation of CSI supports raw block volumes. Inside a container, this feature enables a persistent volume to appear as a block device instead of as a mounted file system. This feature can be useful for applications that do not work with NFS or FUSE or perform better on a standard Linux file system, such as EXT4 or XFS.

The following (or later) releases of the storage plugin support raw block volumes:

For more information, see Raw Block Volume Support in the Kubernetes documentation.
