		+	IVR - Inter VSAN Routing - også kendt som Fabric Routing giver forbindelse mellem Fabrics uden at sammenkoble dem direkte.
		+	*Giver separation mellem Fabrics hvis der sker fejl i den lokale SAN
		+	*Kan dele data mellem tusindvis af enheder
		+	*Deling af centrale enheder mellem flere SAN's (Backup centralt af flere SAN's)
		+	*Enheder i flere VSAN's kan kommunikere

		+	*Kører på gigabit Fibre Channel
		+	*Protokollen har bedre flowcontrol end ESCON og kan anvendes over store fysiske afstande.
