System Configuration<br />
Figure 13: System Controls - System Config<br />
• Using the "System Config" you can administer extensive settings on your gemSTONE:<br />
• System Beeper Setting. Turns the speakers on and off. If it is turned on, you hear a beep if<br />
problems arise with the gemSTONE. By default, the speaker is on.<br />
• Background Task Priority. Following a hard drive processing power is needed to integrate a new<br />
hard disk. This computing power can be adjusted in four steps. The higher the priority, the<br />
faster the hard drive is integrated into the RAID The default value is 80%.<br />
• Terminal Port Configuration. You can also configure using a null modem cable connected to the<br />
gemSTONE. You must install a terminal program on your computer, thegemSTONE settings<br />
must match those of the terminal program.<br />
• JBOD/RAID Configuration. Here you can choose to work the Gemstone as a JBOD or a RAID. The<br />
default value is "RAID".<br />
MAX SATA Mode Supported. Here you can set the maximum value of the SATA protocol. The<br />
Default value is "300 + SATA NCQ“<br />
o SATA150 should be chosen for drives that are older though after the SATA I standard.<br />
o SATA150+NCQ should be chosen for drives that are older though after the SATA I standard<br />
and utilise Native Command Queuing. Look at the documentation of the hard drives.<br />
o SATA300 should be chosen for drives that are more modern and to the SATA II standard.<br />
o SATA300+NCQ should be chosen for drives that are more modern and to the SATA II<br />
standard and utilise the Native Command Queuing. Look at the documents to the hard disks.<br />
• Host NCQ mode. If you have connected the eSATA GEMSTONE through an interface to your<br />
computer, you can improve performance slightly (~ 10%), if you know the type of your SATA<br />
controller in your computer. If you do not this, please leave the setting to "disabled".<br />
o Disabled. Uses no optimisation.<br />
o ESB2/MAC Pro/ Silicon Image. Use this option if you are one of ESB2 SATA controller, Silicon<br />
Image or use a MAC Pro.<br />
o ICH is the chipset of Intel<br />
