Chapter 1. Introducing the SAN48B-5
The IBM System Storage SAN48B-5 is a 48-port auto-sensing 2, 4, 8, or 16 Gbps as
well as 10 Gbps Fibre Channel (FC) switch for Fibre Channel Storage Area
Networks (SANs). The SAN48B-5 is an enterprise-class 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 small to medium-sized workgroups.
The switch's 48 ports in a one rack-unit (1U) height enable the creation of very
dense fabrics in a relatively small space.
The SAN48B-5 offers Ports on Demand (POD) licensing as well. Base models of the
switch contain 24 ports, and up to two additional 12-port POD licenses can be
purchased. The switch provides excellent overall value as the foundation of a SAN
with the ability to grow with an organization’s SAN needs.
The SAN48B-5 supplies Reliability, Availability, and Serviceability (RAS)
performance and scalability requirements of an enterprise switch along with
interoperability and ease-of-use advantages.
The switch can also be configured in Access Gateway mode that lets you configure
your Enterprise fabric to handle additional N_Ports instead of domains. By
reducing the number of domain IDs and ports you simplify configuration and
management in a large fabric. Switches in AG mode are logically transparent to the
host and the fabric. You can increase the number of hosts that have access to the
fabric without increasing the number of switches.
The switch's depth of less than 18 inches allows for greater installation flexibility.
