Data-at-rest encryption overview

You can enhance data security on a cluster that contains only self-encrypting-drive nodes, providing data-at-rest protection.

The OneFS system is available as a cluster that is composed of OneFS nodes that contain only self-encrypting drives (SEDs). The system requirements and management of data at rest on self-encrypting nodes are identical to that of nodes that do not contain self-encrypting drives. Clusters of mixed node types are not supported.
