Compaq Infortrend Stripe Size, Beginning Initialization, Stripe size Default ?, On-Line Mode

Users may proceed with array configuration, e.g., including this array in a logical volume.

Array initialization can take a long time especially for those comprised of large capacity. Setting to “Online” means the array is immediately accessible and that the controller will complete the initialization when IO demands become less intensive.

Stripe Size:

This menu allows you to change the array stripe size. Setting to an incongruous value can severely drag the performance. This item should only be changed when you can be sure of the performance gains it might bring you.
