[ewg] Soft-RoCE on NetEffect NE020 10Gb RNIC

As I understand it,  Soft-RoCEE is only to allow developers to run
InfiniBand VERBS over Ethernet cards that do not have native RoCEE drivers.
The latter requires RDMA and CEE, whereas Soft-Rocee does not have these
dependencies.   The NetEffect and Mellanox cards both have RoCEE drivers in
OFED and these should be used in preference. The maintainers will accept
bugs on these.

 

Soft RoCEE is not currently included or maintained by OFED and is maintained
separately by  systemfabricworks

Hi Mr Lee,

 

I will respond off list since rxe is not technically part of OFED.

Dear all,

 

I have installed the OFED-1.5.2-rxe on our linux host, which has three
network interfaces, Broadcom Corporation NetXtreme II BCM5709 Gigabit
Ethernet NIC, Mellanox Technologies MT26478 [ConnectX EN 40GigE, PCIe 2.0
5GT/s] and NetEffect NE020 10Gb Accelerated Ethernet Adapter (iWARP RNIC).
The Soft-RoCE can work on the first two cards, but when I applied the
Soft-RoCE to the Neteffect card and use "ibv_devinfo" to view the RDMA
device, I got  following errors on some of the hosts in our cluster, and the
whole OFED stack doesnot work.

However, some hosts in our cluster can make Soft-RoCE work on the iWARP RNIC
with the same configuration. The info is as follows,

So, my question is why is that Soft-RoCE does not work on some of the
NetEffect iWARP RNIC's, but does work on the other NetEffect iWARP RNIC's?
All iWARP RNIC's are on different hosts of the same cluster, and connected
via a Juniper EX 2500 switch. 

 

Any help will be greatly appreciated.
