I seem to remember that it used to work even with 8.4. So maybe there is/was some variant of the SDP module out there that implements the sk_state_change() hooks DRBD uses to notice the established connection. Or maybe I misremember. So maybe, yes, we may need to drop it from the docs. > https://drbd.linbit.com/users-guide/s-replication-transports.html > Also - If you are curious: > > A few lines from the NPtcp test of regular TCP versus SDP over the You can safely assume I am aware of such benchmarks ;-) But they do not say much about what you can get for *DRBD* over SDP. But yes, if that was not the case, we had never even bothered to implement SDP. >From what I hear, SDP is considered "dead" anyways, and the future is in "native" RDMA ("verbs").

IP (v4 or 6, does not matter) is what everybody is using.
