Chapter 1. Introducing the SAN40B-4 switch

The IBM System Storage SAN40B-4 is an enterprise-class 8 Gbps Fibre Channel
switch that is designed to handle the large-scale SAN requirements of an
enterprise, and can also be used to address the SAN requirements of a small to
medium-sized workgroup. It runs on the Fabric Operating System (Fabric OS) and
is compatible with other IBM switches, which enables seamless connectivity into
heterogeneous SAN environments. Because the switch is scalable through
additional port activation, you can use it as a foundation switch for a small storage
area network (SAN) and continue to use it as a building block as the SAN grows.
