Learn about the Shared Memory Communications over RDMA (SMC-R) protocol and its implementation in storage software through this 15-minute conference talk by Konstantin Maksimov at DevConf.CZ 2025. Explore the fundamentals of SMC-R protocol, which provides Remote Direct Memory Access (RDMA) communications to TCP endpoints transparently to socket applications. Discover the key differences between SMC-D and SMC-R protocols, including their respective advantages and disadvantages. Gain insights from real-world implementation experience of SMC-R protocol in Software-defined storage (SDS) on IBM Linux on Z platform. Examine performance evaluation results comparing SMC-R with SMC-D and traditional TCP protocols. Understand potential bottlenecks in SMC-R protocol implementation within the Linux kernel and learn practical techniques for enabling SMC sockets in any application.
