Re: SR-IOV on ESXi 5.1
What other solutions to use RDMA/SDP in multiple Virtual Machines (vSphere) over one single Mellanox card are existing? Is it possible to use the VMXNET 3 for such possibilities? With which OFED...

UD is becoming more performance oriented than ever before, and can cross our IB to Ethernet gateways. CM cannot cross gateways which is a major issue for compatibility. Linux still has both CM and UD...

Sounds good (especially the ubuntu part :-) Do you know if the beta (and/or GA) supports ConnectX-2 and works with BX5020 and IS5030? When I asked support, early march, to participate in the beta...

OK, I finally received my switch box. I connected everything and nothing happened. I then did as justinclift suggested below. I rebooted and everything seems to be lit up now. Thank you very much...

Cool. The commands you'll probably find most useful right away are: ibv_devinfoibaddribdiagnetibhostsibnodesibping The config files you'll probably find most interesting are in the /etc/rdma/...

Justin, I think I don't have something configured properly. Here's what I get: [root@think172 ~]# ibv_devinfoNo IB devices found[root@think172 ~]# ibaddribwarn: [20819] mad_rpc_open_port: can't open...

Hmmm, it kind of sounds like you're just wanting to run the adapters in native 10 GbE mode instead of in IB mode. That's super simple to do if you're using the Infiniband stuff that comes with CentOS....

Oops, I gave you bad info there. Didn't notice/remember that you're using EN cards. i.e. Ethernet only ones I don't think the Infiniband specific commands work with them. Guessing that your adapters...

Are the ports connected to an Ethernet switch now?Can you check the configuration of the switch ports, speed, autonegotiation, and make sure the switchports are "no shutdown".You can also crossover...

How about L2 bridging Ethernet to IPoIB without a gateway? Say using a linux box with IB and Ethernet ports.
View ArticleRe: What questions do you have about IPoIB for Mellanox?
It would be extremely slow. Everything is done in software, kernel in particular, and that means huge latency.You can try with the standart Linux bridge. Just add eth0 and ib0 to the same bridge and it...

Because more is better J I edited the commands in the reply, trying to make it clear what I did. Ifconfig doesn't accept 5-segment ipv4 addresses (it outputs 'unknown host'). Thanks for the list of...
