Best pratice for vSphere 5 Networking

Hi all,

Considering of the following enviroment:

     1) 4 Physical Servers,each server has 16 Nics (Gigabit) will install vSphere 5 std.

     2) 2 Switches with stack function for SAN Storage

     3) 2 Equallogic PS4000 SAN (Dual controller )

     4) 2 Switches for virtual machine traffic

Regarding to the networking, I plan do create some vSwitches on each physical server as follows

     1. vSwitch0 - used for iSCSI storage

         6 NICs Teamed, with IP-hash teaming policy,  multipathing with iSCSI Storage;and the stroage load balancing is Round Rodin(vmware)

         ( vmware suggests use 2 NICs for 1 IP storage traget, I am not sure)

     2. vSwitch1 - used for virtual machine

         6 NICs Teamed for virtual machine traffic, with IP-hash policy

     3. vSwitch2 - for managment

         2 NICs Teamed

     4. vSwitch3 - vMotion

          2 NICs teamed

Would you like kindly give me some suggestions?
