Does the DSS support iscsi multipathing from xen servers, and if so, will this work in failover with 2xdss servers?

Each Xen node has 2xGE dedicated to iSCSI and the DSS servers each have 6xGE for iSCSI traffic, and 2xGE for replication traffic. We initially had the 6xGE setup in a bond and had a bond on the Xenserver side, and we are now being told we would get better performance if we used multipathing on the Xen side. To do this on the DSS server side however, we need to create multiple single GE targets and not use bonding, or create multiple smaller # of GE bonds, since the xen server has to see multiple paths via iSCSI for it to work.

This possible on the DSS side, and if so, do you agree performance would be better?

Thanks in advance!
