Figure 1 Configuration Overview
Configuration Support
The SNC provides one FC interface. The FC interface is configured with a small form factor pluggable
transceiver (SFP). In addition, the SNC has two Ultra2 SCSI interfaces.
Address Mapping
The SNC maps addresses across and between these different interfaces and preserves the persistency of
the address maps across power ups of systems, devices, and the SNC.
Interface Protocol Awareness
The SNC processes SCSI-3 and SCSI-2 protocols for disk, tape, and tape medium changer devices. It can
report the host and devices that are attached to its interfaces. The SNC has the capability to manage the
access security between end points on the FC interface and the SCSI channels.
FC Interface
Interfaces for host and device attachment include one, 1- and 2-Gb/s bi-directional Short Wave connection.
The SFP can interoperate with both 2 Gb/s and 1 Gb/s data links. The SFP is hot-swappable and is the only
component, except for the SNC module itself that is a field replaceable unit (FRU). Refer to
Removing and
Replacing the SFP on page 27.
Cables should have a duplex LC connector on the SFP end and a connector appropriate to the HBA in use
on the host end.
The FC interface supports the following Public and Private Loop modes:
