Initiate Wide Negotiation
– The setting for this option determines whether
the channel initiates negotiation with the SCSI device for Wide SCSI data
transfers. When set to Yes for a SCSI device, the channel initiates Wide
negotiation with the SCSI device. When set to No, the channel does not
initiate Wide negotiation with the device. The channel, however, always
responds to Wide negotiation if the SCSI device initiates it. The default
setting is Yes.
To enable Ultra2 Speed (80 MB), first enable
Initiate Wide Negotiation. Then select the
highest available setting in the Maximum
Sync Transfer rate option.
•
Enable Disconnection
– The setting for this option determines whether the
channel allows a SCSI device to disconnect from the SCSI bus (sometimes
called Disconnect/Reconnect). Enabling disconnection allows the channel to
perform other operations on the SCSI bus while the SCSI device is
temporarily disconnected.
When set to Yes, the SCSI device may disconnect from the SCSI bus. The
SCSI device, however, may choose not to disconnect, even if permitted by the
channel (this can usually be configured on the SCSI device). When set to No,
the SCSI device cannot disconnect from the SCSI bus. The default setting is
Yes
.
To optimize SCSI bus performance, leave Enable Disconnection set to Yes if
the channel connects to two or more SCSI devices. If the channel connects to
only one SCSI device, set Enable Disconnection to No to achieve slightly
better performance.
