SnapDrive for Windows supports several different iSCSI configurations.
Single host direct-attached to a single storage system using iSCSI
You can configure SnapDrive for Windows to use a GbE crossover cable to attach the host directly to the storage system, an arrangement that minimizes latency and eliminates unwanted network broadcasts.
Single host attached to a single storage system through a GbE switch
You can configure SnapDrive for Windows to use a single-homed configuration that places a network switch between the storage system and the host, an arrangement that provides good performance and also segregates host-storage system traffic by directing it through a single pair of switch ports.
Single host attached to a single storage system through a dedicated switch
You can configure SnapDrive for Windows to use a multihomed configuration with a GbE switch between the storage system and the host, an arrangement that, in addition to providing good performance and segregating host-storage system traffic to the dedicated switch, also minimizes disruptions in situations where network routing configuration changes frequently.
