Customer has HP servers with Mellanox controllers.
Q. is Windows server with SMB Direct over RoCE attached to ACI supported or not ?
shows that UCS 2.2.4 supports RoCE of course for Cisco servers and VIC adaptors.
What are the requirements for SMB Direct over RoCE? As per my understanding I think it's only QoS and Priority Flow Control. ACI supports both of these starting with version 2.1(PFC).
I believe RoCE is more than CE (Converged Ethernet=PFC,....). e.g. there is RoCE V1 = L2, and RoCE V2 = L3.
So what are the requirements? In every documentation the only requirement is a lossless fabric.
I know that RoCE is supported by adaptor vendors, like Emulex, Qlogic, Mellanox,and Cisco
UCS 2.2.4 introduced support of RoCE (only Cisco, VIC 13xx, adaptors, no interop with Mellanox, only W2012 R2, I’ve not seen W2016 support).
If it would only mean PFC, why is then the documentation and spec. of ACI not claiming RoCE support. See also my other post, regarding FCoE across the ACI fabric.
