MacOS – Does OS X support SMB Direct (RDMA)

macosNetworksmb

SMB over RDMA technology was introduced in SMB 3.0, and gained broader popularity in the last couple of years.

Does anyone know if I can recompile sharing or enable this on macOS?

Best Answer

Well, got this from ATTO tech support today:

macOS (macOS 10.14.x, macOS 10.15.x Catalina, & macOS 11.x Big Sur) does not support SMB Direct, nor RoCE.

:-(

I sent a feature request to Apple. I'm sure that because I said so they'll get right to it. ?

sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.smb.server.plist EnabledServices -array disk
