ATTO BIOS striping
Maximum data rate can be obtained by enabling an optional feature within the ATTO controller. You will
need to purchase ATTO’s ExpressRAID software to enable this BIOS striping feature.
Striping can be done either using Windows (NT, Win2K, XP) built-in striping tool, or ATTO’s BIOS
Striping. We recommend using ATTO’s BIOS striping as this is more efficient and results in faster data
rates. Windows striping uses smaller block requests whereas ATTO’s BIOS stripe uses larger and more
efficient block sizes.
Using the BIOS striping, a pair or more of the U320-R can be striped together, this in turns is seen as one
large disk drive to the Operating System.
In preparing the U320-R’s two steps are required:
1) Use the ExpressRAID (BIOS stripe) to stripe the U320-R’s.
2) Use Windows Disk Administrator (NT) or Disk Manager (Win2K, XP) to format the BIOS stripped
disk.
