vmware native multipath with celerra Ns40

Hello ,

we have several vsphere hosts and a celerra Ns40. We are currently using link aggregation with iscsi. we want to use  vmware native multipath. I think we need to configure an iscsi target with multiple ip address , each esx host has 4 uplink port  for the iscsi network. we have 12 iscsi target at the cellera . Do we need to configure each iscsi target with 4 ip address ? is there any detail document about vmware native multipating with celerra  ?

Thank you.
