I don't think the WinOF opensm will support this, but I'm not certain. >And I can't do that even adding a Linux host that runs opensm (OFED version)? I would expect that this is possible. >Traffic separation based on HCA port could be an option, but I need to think >more about that. >What can you do with that kind of QoS? More simply, this would allow you to group hosts into different traffic priority groups. >Do you mark this HCA port as high-priority, that HCA port as low-priority, etc? >What happens when a high-pri port sends traffic to a low-pri port? And vice- >versa? There should be rules in the opensm QoS config file that will determine this. I've copied the general list on this reply. Sasha, Hal, or someone that deals more directly with opensm will be able to direct you better. >What happens when a high-pri port sends traffic to a "normal" port (a port that >is not marked as high-priority nor low-priority)? >I'm using only RDMA Write with Imm in my system, although I'm interested in >what happens on all types of traffic. >If you know of a document that explains that, please let me know, I haven't >found it by now. The OFED opensm includes documentation on setting up QoS. It's in opensm/doc in the management source tree. - Sean _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
