Lightly browned and well buttered. A solid pick from the rack.
Summary
This technical documentation explains how to configure the Linux SMB client and server to use SMB Direct, which implements SMB3 over RDMA (Remote Direct Memory Access) for high-performance networking. The document provides an overview of SMB Direct's benefits (high throughput, low latency by bypassing TCP/IP stack), installation requirements for RDMA devices, and testing capabilities against KSMBD kernel-space SMB server.
Key quotes
· 4 pulledThe Linux SMB kernel client supports SMB Direct, which is a transport scheme for SMB3 that uses RDMA (Remote Direct Memory Access) to provide high throughput and low latencies by bypassing the traditional TCP/IP stack.
SMB Direct on the Linux SMB client can be tested against KSMBD - a kernel-space SMB server.
Install an RDMA device. As long as the RDMA device driver is supported by the kernel, it should work.
This document describes how to set up the Linux SMB client and server to use RDMA.
