The Catalyst 3750 cannot be used for fibre channel SANs at this time. It can be used in conjunction with the MDS9500 switch with an IP storage services module (IPS module) or an SN5428-2 storage router to connect hosts to storage using iSCSI or geographically separate switches using FCIP. The MDS9500 and SN5428-2 have gigabit Ethernet interfaces that could be connected to a 3750 with GigE.
