RoCE interop. support with Mellanox

[Walter Dey]

2.4.4b introduced RoCE for W 2012 R2

I have a customer, that wants to use it between UCS blade servers with VIC-1340 and a storage server with Mellanox Connect-X3.

However, it's not working, always fall back to TCP (see attachment)

On the SMB Direct Interfaces they usually  set NetQosPolicies and NetQosFlow Control. Doing this on the RDMA VICs fails, see attachment.

Q. is interop with Mellanox tested and supported ?

Q. is NetQosPolicies and NetQosFlow Control on RDMA interfaces supported ?

According to Cisco TAC: no interop tests have been done nor planned fir Mellanox Connect-x.

It seems to be planned for RoCE V2 next CY.

Hi Matthew

I have to revise my statement;

Due to the fact that I didn't receive any answer for more than 2 weeks, I urged the customer to open a TAC case; I checked today; instead they contaced to local CSE which asked the question on a Cisco internal mailer; the answer he got came from PM (???).

PS. please clarify if something is not correct in the statement ?
