[Disksim-users] help for the construction of raid 5 in disksim and the way of trace acquisition

[Yinliang Yue]

The answers to the first question:

The following combination in  synthraid5.parv  shows that you are using a
RAID5. For the reason, please see the manual.

   Distribution scheme = Striped,
   Redundancy scheme = Parity_rotated,


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.
