That would work but when you have a failover event, the all of the IP addresses will move to the HA-Partner in 7-Mode and you would lose connectivity to the lun. If cDOT, the IPs (LIFS) would not move and MPIO with ALUA is required. I wouldn't direct attach any SAN protocol (not supported for cDOT). With FC it is supported direct attached (7-Mode ONLY, as long as native FC connected to both controllers in the ha-pair), but I don't like that setup...always prefer multipath across two switches.
