Chapter 4. Technology Previews
This section provides an overview of Technology Preview features introduced or updated in this release of Red Hat Ceph Storage.
Technology Preview features are not supported with Red Hat production service level agreements (SLAs), might not be functionally complete, and Red Hat does not recommend to use them for production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

The Ceph Object Gateway now supports NFSv3 protocol as a technology preview
Support has been added for accessing Ceph objects by way of the NFSv3 protocol, alongside the existing NFSv4. The NFSv3 protocol has been superseded by NFSv4, but remains widely supported and used.
Object upload semantics are slightly different than when using NFSv4 due to the lack of OPEN and CLOSE operations in NFSv3. For NFSv3 clients, the Gateway emulates OPEN operations, and when objects are uploaded, commits the update transaction when no data has been seen for a short time period, instead of on CLOSE.
Additionally, NFS-Ganesha now fully supports the ability to export Amazon S3 object namespaces by using NFS 4.1. For details, see the Major Updates section.
