I don't have a network diagram handy but can describe ours (we have a CX3-20c).
We have two dedicated 48-port Gb Ethernet switches for iSCSI (switch A and switch B). Switch A has a connection to SP_A port 0 and SP_B port 0 on the SAN (using addresses on Class C subnet 192.168.0.x), likewise Switch B connects to SP_A port 1 and SP_B port 1 using IPs on subnet 192.168.10.x
On the hosts they have two separate dedicated iSCSI NICs, NIC 1 on subnet 1, NIC 2 on subnet 2 (no default gateways configured as the LAN connection has that).
The result is 4 active paths display in PowerPath and is the same topolgy as our fibre channel stuff.
