Introduction to HP Fibre Channel Products ■ Arbitrated loop switches - Fibre Channel arbitrated loop (FC-AL) switches are low port count, low-bandwidth products. HP offers related products that act as loop-switching hubs and fabric-attach switches. These switches provide connectivity between attached FC-AL devices, and between FC-AL devices and switched fabric elements. This connectivity allows low-cost or low-bandwidth workgroup (edge) devices to communicate with fabric devices (servers, storage devices, or other peripherals), and ultimately be incorporated into an enterprise SAN environment. Directors and switches are managed and controlled through a High Availability Fabric Manager (HAFM) server, available from HP with the HAFM, Director 2/64 Product Manager, Director 2/140 Product Manager, Edge Switch 2/16 Product Manager, Edge Switch 2/24 Product Manager, and Edge Switch 2/32 Product Manager applications installed. The HAFM server is a notebook personal computer (PC) that provides a central point of control for up to 48 managed products (directors and switches). Managed products and the HAFM server communicate on a local area network (LAN) through one or more HP-supplied 10/100 Base-T Ethernet hubs. Hubs are daisy-chained as required to provide additional Ethernet connections as more directors or switches are installed on a customer network. Refer to Chapter 2 for information about managing products through the HAFM server. Chapter 2 also describes switch management through simple network management protocol (SNMP) workstations, through the Internet using an Embedded Web Server (EWS) interface installed on the product, and through inband (Fibre Channel) application clients. Directors and switches can be configured to order in an HP-supplied 19-inch equipment rack. Figure 1 on page 17 illustrates an equipment rack. 16 SAN High Availability Planning Guide
