iSCSI MPIO, how many path do I need to create

Hi,

I've a server with 4 NIC connection to a DELL MD32xx which have 8 NIC.

My question is how many path do I need to create under iSCSI connection.

Do I need to create a path from each Server NIC to each MD32xx NIC, which will make 32 connection (and doesn't make sense).

If not, how should I proceed, I've looked at many example and none seem to cover that kind of situation, they just directly connect the server NIC to the MD32xx NIC instead of going through switch for redundancy.

Thank

ML
