To modify settings on this panel:
•
•
•
•
Use the arrow keys to select the parameter to modify. Press Enter to edit the value.
Use the arrow keys to select the new value or press Esc to quit. Press Enter to validate the new value.
The fields in this panel are described below:
1 Initiate Sync Negotiation
The host adapter always responds to synchronous negotiation if the SCSI device initiates it. However, when this field is set to Yes, the host adapter will initiate synchronous negotiation with the SCSI device.
Some older
2 Maximum Sync Transfer Rate
The default value is 10.0 MBps for
Older
3 Enable Disconnection
This option determines whether the host adapter allows a SCSI device to disconnect from the SCSI bus (also known as the Disconnect/Reconnect function).
You should leave the option set to Yes if two or more SCSI devices are connected to optimize bus performance. If only one SCSI device is connected, set Enable Disconnection to No to achieve better performance.
4 Send Start Unit Command
Enabling this option reduces the load on your server′s power supply by allowing the SCSI devices to
