Hi, I'm testing iscsi multipath with gmultipath, the setup is: Target: Dell MD3000i with double controller RAID 6 Initiator: Custom server with dual Gigabit Ethernet, FreeBSD 10.3 RELESE The MD3000 expose the lun on two different subnets, 192.168.253.253, 192.168.252.253. From the initiator i connect to both the ports. TargetAddress = 192.168.253.253 Connected: da0 TargetAddress = 192.168.252.253 Connected: da1 I have setup the system to use gmultipath: gmultipath label -v TEST /dev/da0 /dev/da1 And then i've testing the performance, both with active/passive and actve/active. From what i have seen, the performance don't change that much, there is some stuff to configure that i'm missing? Copying form the internal drive to the target dd if/of bs=1m (4.7GB) A/P 65MB/s dd if/of bs=1m (4.7GB) A/A 73MB/s Copying from the target to /dev/null, same file A/P 101MB/s A/A 123MB/s Thanks
