<div><font size="2"><font face="tahoma,sans-serif">The answers to the first question:</font></font></div>
<div> </div>
<div>The following combination in synthraid5.parv shows that you are using a RAID5. For the reason, please see the manual.</div>
<div> </div>
<div><font size="2"><font face="tahoma,sans-serif"> Distribution scheme = Striped,<br> Redundancy scheme = Parity_rotated,</font></font></div>
<div> </div>
<div> </div>
<div>Please see the the function named logorg_maprequest() in disksim_logorg.c if you want to make a deep analysis of the mechanism of RAID5.</div>
