hello cinder team,
I wanted to know if we have support for NVMEoF with TCP transport between servers and the target? Any documentation/reference would be appreciated.

Hi, As far as I know both Cinder's target [1] and OS-Brick's connector [2] support TCP/IP transport, but I have never tested it. What I'm not too sure about is how thorough the testing of the NVMe-oF code in OpenStack really is, since it's not currently flushing the buffers on disconnect [3], and recently found out that it's unlikely to work with encrypted volumes (because it's returning a real device and not a symlink). These 2 bugs should be easy to fix, but both time and the appropriate hardware is required to validate it. Cheers, Gorka.
