. When a Fibre Channel device connects to a director or fabric switch, the device receives a unique 24-bit (three-byte) network address composed of domain, area, and port bytes. This address is used for routing data through the fabric.

These issues make it difficult to connect directors or fabric switches from different original equipment manufacturers (OEMs) to build a large SAN.

a three-tier model that defines SAN routing hierarchy: • Tier 1 - The first tier consists of isolated Fibre Channel fabrics (SAN islands). Within each fabric, data is transmitted between directors and fabric switches through E_Port ISLs. 4-8 McDATA Products in a SAN Environment - Planning Manual - Compaq StorageWorks 64 | FW 07.00.00/HAFM SW 08.06.00 McDATA Products in a SAN E - Page 153
. • Tier 3 - To connect geographically remote fabrics or mSANs, the third tier consists of internetworked storage area networks (iSANs). SAN routers transmit data between mSANs through intelligent ports, using Internet Fibre Channel protocol (iFCP).
