Best Practice DS3512 iSCSI Dual CTRL with vSphere ESX 5.0

Hello,
My DS3512 is ready to host three ESX5.0.0,623860 servers in iSCSI Mode.

What is the best practice to configure the iSCSI and ESX? Is it possible to use Round Robin Mulitpathing with this kind of Storage?

What is the supported and recommended way by VMWare/IBM?

Thanks,
