12 Introduction Chapter 1
How the Interface Manager (IM) Works
The IM provides connectivity between a Fibre Channel (FC) switched fabric
(FC-SW) or Fibre Channel arbitrated loop (FC-AL) and up to 20 Ultra-2 SCSI
buses.
The IM contains slots for up to eleven (one slot is reserved for future expansion)
Fibre Channel cards. Each card connects a FC port to two Ultra-2 SCSI ports.
The IM also contains a Remote Management Card (RMC) in slot 1, and a
controller card in slot 2. The RMC provides the user with a serial port for initial
setup, as well as Telnet and Web Administrator - HTTP access to any of the
cards in the IM.
Each FC card translates the FC protocol (FCP) to and from the SCSI protocol so
that FC and SCSI devices can communicate. The FC card attaches to a FC host,
hub, or switch and transfers the command, data, and status information to
SCSI targets. Packets are transferred transparently by the IM between a host
and targets and vice versa.
SCSI and Fibre Channel connectors are accessed from the front of the IM.
Ethernet and serial ports provide the means for configuring and managing the
IM. A power connector is located on the front of the Interface Manager.
