Ultra2 Scsi I/O Interfaces - ADIC Scalar 100 User Manual

that is a Field Replaceable Unit (FRU). See "Removing and Replacing the GBIC" on
page 154.
Cables should have a duplex SC connector on the GBIC end and a connector appropriate
to the HBA in use on the host end.
Fibre Channel interfaces support the following Public and Private Loop modes:
• Target
• Initiator
• Target and Initiator
Fibre Channel Interfaces also support the following connection options:
• Loop
• Point-to-Point
• Loop Preferred
The Fibre Channel interface controller is in compliance with the following standards and
specifications:
• Fibre Channel Arbitrated Loop (FC-AL-2) working draft, rev 6.4, August 28, 1998
• Fibre Channel Fabric Loop Attachment (FC-FLA) working draft, rev 2.7, August
12, 1997
• Fibre Channel Private Loop SCSI Direct Attach (FC-PLDA) working draft, rev 2.1,
September 22, 1997
• Fibre Channel Tape (FC-TAPE) profile, T11/98-124vD, rev 1.13, February 3, 1999
• Fibre Channel protocol SCSI (FCP-SCSI)
• Fibre Channel internet protocol (IP)
• Fibre Channel virtual interface (FC-VI)

Ultra2 SCSI I/O Interfaces

• Four Low Voltage Differential (LVD) Ultra2 SCSI channels with internal
termination.
• SCSI channels have automatic speed and width negotiation capability for wide or
narrow bus widths and Standard, Fast, Ultra or Ultra2 speeds. These parameters can
be viewed from the ADIC Management Console.
• SCSI channel support for up to 15 SCSI target IDs and up to 32 LUNs per ID
(subject to an overall total of 2048 devices). The SNC uses one LUN for command
and control so that the remaining 2047 LUNs are available for SCSI devices. For
each Fibre Channel interface, the SNC occupies one Fibre Channel ID and all SCSI
target devices are available as LUNs on the same Fibre Channel ID.
