Hi the open-fcoe experts: I'm working on the FCoE initiator offload(performance) test on Linux with Intel ixgbe (Niantic 82599 driver). Could you guys give me some instruction about what kind of prerequisite must to be done for this offload(performance) test .
Based on my knowledge , following is my steps to do the offload test. (eth4 is the ixgbe interface) 1. service dcbd start 2. ifconfig eth4 mtu 2500 3. [r...@petpig ~]# dcbtool sc eth4 dcb on Version: 2 Command: Set Config Feature: DCB State Port: eth4 Status: Successful 4. fcoeadm -c eth4 ----------------------------------------------------------- environment is : The target is Sun storageTek 6140 array FCoE switch is Cisco Nexus . self-build kernel version : 2.6.31 i386 fcoe-utils: open-fcoe-2.6.30.tar.gz The performace data(by iometer/vdbench) I got after doing the steps above is not very well, so I was wondering if the dcbx ON the interface can 100% guarantee the hardware's offload is enabled ? or some other critical steps I missed ? what kind of way I can double check if the hardware's (Niantic ixgbe) offload is enabled or not ?. as far as I can see is one message from dmesg: ixgbe: eth4: ixgbe_set_fcoe_queues: FCOE enabled with DCB Really really appreciate any comments/instructions/suggestions you can offer me to help me move on , thanks ! /Carol _______________________________________________ devel mailing list [email protected] http://www.open-fcoe.org/mailman/listinfo/devel
