Sync Rate (MB/s)
Choices: Sync DT IU (320, 160), Sync DT (160, 80, 40), Sync ST WIDE
(80, 40, 20, 10), Sync ST Narrow (40, 20, 10, 5)
Default: Sync DT IU 320.
If synchronous transfers are enabled, the sync rate speci
fi
es the maximum rate
at which host bus adapter negotiates with the selected target ID. Set the rate
to the maximum value supported by the host adapter. If excessive SCSI errors
occur, you have long cables, or there are many devices on the bus, you
might want to reduce the
Sync Rate
value. Slowing the transfer rate may
increase the reliability of the SCSI bus.
Wide Transfers
Choices: Disabled, Enabled
Default: Enabled
Speci
fi
es whether the initiator negotiates wide data transfers. If the parameter
is disabled, narrow data transfers are negotiated.
Wide Transfers
is
automatically set to Enabled when the
Sync Rate
speci
fi
es a DT rate. The
DT sync rates must have wide data transfers.
