Introduction to HP Fibre Channel Products
■
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.

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.

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.
