Fibre Channel Port
The SCSI extender has several types of data connections:
•
One SCSI channel port on the Fibre-to-SCSI extender connects to the SCSI port
on a supported storage device.
•
One SCSI channel port on the SCSI-to-Fibre extender connects to a supported
SCSI port on the NonStop S-Series Server. For more information, refer to
Table 1-4, Supported SCSI Ports, on page 1-6.
•
Fibre Channel gigabaud interface connector [GBIC] connects to the other SCSI
extender.
•
RS-232 serial port is unused.
Fibre Channel Port
The SCSI Extender has gigabaud interface connector (GBIC) housing for optical
cabling. It supports data transfer up to 100 MB/sec. The Fibre Channel (gigabaud
interface connector [GBIC]) port connects to the other SCSI extender.
Connect the SCSI extender directly to fibre channel devices. Only fibre channel
arbitrated loop is supported. For NonStop S-series servers, fibre channel is used only
to connect the SCSI extenders together.
Proper FC components must be used (for example, GBICs and fibre channel cables).
A GBIC connector must be used. The GBIC connector is available in Long Wave
Optical.
Table 1-3 lists the maximum distances for the fiber cables using the long wave GBICs.
SCSI Port
The SCSI Extender is a High-Voltage Differential (HVD) model that supports Ultra wide
data transfer at up to 40 MB per second per channel and has internal SCSI
termination.
•
The Fiber-to-SCSI extender (CTFSE) contains one SCSI channel which connects
to the SCSI port on a supported storage device.
•
The SCSI-to-Fiber extender (CTSFE) contains one SCSI channel which connects
to a supported SCSI port on the NonStop S-Series server as shown in Table 1-4
on
page 1-6.
