  • SMB Direct is a transport scheme for SMB3 that uses RDMA for high throughput and low latency.
  • Installation requires an RDMA device, a kernel with SMB Direct support (5.15 or later), and cifs-utils.
  • Configure the RDMA stack by enabling RDMA support in the kernel and setting up the appropriate modules.
  • Enable SMB Direct support in both server and client kernel configurations.
  • Set up a KSMBD server with multi-channel support and mount the share using the 'rdma' option.
  • Verify SMB Direct usage via dmesg or /proc/mounts.
