if possible, I think you should combine the the ports in one vswitch and use only one vlan for ISCSI traffic and have more than 2 VMKernel ports for the ISCSI, It will give you multipathing and also redundancy and you can set it up as following
As vmotion is not used that much , you will have two 10 GB multipath and redundant Connection for ISCSI
Kind Regards,
