Controller tree object Changing the stripe-unit size

Notes:
  1. This action is supported in bootable-CD mode only.
  2. This action is not supported on the ServeRAID-7t controller, ServeRAID SAS conrollers (8i/8k/8k-l), and the integrated RAID controller.
  3. On ServeRAID-7t controller and ServeRAID SAS controllers, use the configuration wizard to change the stripe-unit size.

Use this action to set the size of the chunk of data that the controller reads from each physical drive at a time. To maximize overall performance, choose a stripe-unit 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.

  1. In the Enterprise view, click Controller (controller).

  2. Right-click Change stripe-unit size a stripe-unit size. The following choices are available:
