The Ceph storage ecosystem currently covers the full range of File, Object and Block access with Ceph-specific protocols. Standard NAS protocols such as SMB and NFS were recently added and expanded to allow client-native protocols to consume this scale out file storage.
The team at Red Hat and then IBM have been looking into ways to enhance our storage stack with an SMB3 gateway to our Ceph File System. Based on the feedback we’ve received on the business side as well as the Open Source community IBM plans to add SMB as a fully integrated component of Ceph - upstream and downstream.
In our talk we want to highlight some of the implementation aspects that need to be addressed for adopting this plan. We want to share the progress we have already achieved for easier management of SMB using Samba, discuss the challenges for SMB clustering and High Availability and finally give an outlook on the upcoming planned features. Our goal is to make SMB a natural choice when connecting clients to the Ceph storage system.
Upon completion, participant will be able to understand usage and management of the SMB support in Ceph.
Upon completion, participant will be able to describe the implementation challenges of layering multiple protocols in a clustered storage system.
Upon completion, participant will be able to setup a plan to use SMB on Ceph according to the feature roadmap.
File Systems & Protocols
USMB2 is a userspace SMB2/3 client for extremely constrained platforms, such as Z80 class machines.
It supports NTLMv2 authentication, mapping shares, opening/reading/writing files with full unicode for share and file names.
This presentation will go through how to design and implement a SMB2/3 client for extremely CPU and RAM constrained systems. What featureset is feasible for 8-bit machines, how and what tweaks are required to make it all work.
File Systems & Protocols
This presentation recaps the features and capabilities added to the upstream Linux in-kernel NFS server from kernels 6.14 through 7.2, covering areas such as dynamic thread pool scaling and the use of server-side O_DIRECT. It will also highlight upcoming additions and the directions driving active development — giving attendees a practical understanding of where the server stands today and where it is headed.

The Linux kernel is about to get native quic and smbdirect support. This talk covers the current status of merging these features into upstream Linux and Samba projects. By the time of the conference most things should be ready to use, so this will also outline what still could be optimized, regarding cpu usage, avoiding memory copy and latency.
File Systems & Protocols
SMB3 POSIX Extensions bring first-class POSIX semantics to SMB, and are now fully implemented and documented across Samba, ksmbd, and the Linux kernel client in their latest stable releases.
This session walks administrators through enabling and using these capabilities in real-world deployments. We conclude by presenting the new home of the protocol specification and outlining how to stay involved as it evolves.
File Systems & Protocols
Samba development has not stopped since SDC 2025:
* SMB over RDMA shows spectacular transfer rates
* The connection ceph and ceph/rgw has improved
* Security of Active Directory protocols has been tightened
* Samba has done development to follow Microsoft on its way to get rid of NTLM
* Entra ID authentication over SMB is an area of active development
* Samba will work better with fuse-based file systems
This talk will present the highlights of latest Samba developments in the above and possibly other areas

The Fibre Channel Channel community began the year with the introduction of 128GFC products, but that's not all! With the release the third generation Security Protocols, Fibre Channel enters a new era of secure fabric solutions. Add to that the completion of the FC-RDMA specification and Fibre Channel lays the groundwork for integration with AI solutions for Fibre Channel SANs. The Fibre Channel team is also pushing ahead on the Gen 9 Fibre Channel specification to deliver 256GFC in the near future.
Now is the time to step back a bit and view the Fibre Channel roadmap. In this session, we discuss the success of the next generation security specifications (FC-SP-3), the technical challenges associated with the creation of 256GFC products, and the impact AI will have on Fibre Channel solutions. Come explore the excitement around FC-SP-3 "Autonomous In-flight encryption" (AIE) that provide a plug-n-play solution for end-to-end security! Take a look at the expansion of Fabric Notifications to produce automated responses to disruptions in the network. Let's see where Fibre Channel is taking you!
We look forward to sharing with you the innovations in Fibre Channel!
