iSCSI Fault Domains

Hi

I'm deploying my first SC5020 array and I have some questions regarding fault domains.

This is a iSCSI array with 8 front-end ports (4 per controller). The iSCSI network is simple: two switches with a single VLAN, front-end ports are split equally between the two switches.

Should I be splitting the ports in two fault domains? If so, should both fault domains include 2 ports from each controller?

Thanks
