Hello, i've an hp p2000 iscsi/fc combo connected with iscsi with an hp dl180 with two dedicated nics. The san has 8 disks in raid 50.
I've configured the san with two different subnets for multipath.
I've created a guest with Windows 2008 R2 on an LVM disk using virtio driver. I've tried to copy a 4GB file and trasfer speed is only 45MB/s, i've created a logical volume formatted in ext3 and i've tried the same operation, transfer speed is 100MB/s.
Multipath seems working, network traffic to the san is distribuited on both nics, but may be that multipath/iscsi is not tuned very well.
Someone has a similar configuration? 45Mb/s is too slow?
