Changing the stripe-unit size

(Bootable-CD mode only.)

Use this action to set the size of the chunk of data the controller reads from each drive at a time.

  1. Select a controller Controller from the Main Tree.
  2. Select Change stripe-unit size from the Actions menu.
  3. Select a stripe-unit size from the menu. The following choices are available:

    With this stripe-unit size, an array can have a maximum of 16 physical drives.

    With this stripe-unit size, an array can have a maximum of 16 physical drives.

    This setting is available if the controller supports an array with 16 physical drives using a 32 K stripe-unit size, or the controller contains no arrays with more than 8 physical drives. Otherwise, this setting is unavailable.

    This setting is available if the controller supports an array with 16 physical drives using a 64 K stripe-unit size, or the controller contains no arrays with more than 8 physical drives. Otherwise, this setting is unavailable.

To maximize overall performance, choose a size that is close to the size of the system I/O request.

Attention: After you configure an array and store data on the logical drives, you cannot change the stripe-unit size without destroying data in the logical drives.
