Figure 1-2   SAN versus NAS

1.4  SAN components

Fibre Channel is the predominant architecture upon which most SAN 
implementations are built, with FICON® as the standard protocol for z/OS® 
systems, and FCP as the standard protocol for open systems. The SAN 
components described in the following sections are Fibre Channel-based, and 
are shown in Figure 1-3 on page 8.
