Abstract
Methods and structure are provided for defining span sizes for Redundant Array of Independent Disks (RAID) systems. One embodiment is a RAID controller that includes a control system and a span manager. The control system is able to identify storage devices coupled with the controller and is able to receive input requesting the creation of a RAID logical volume. The span manager is able to define multiple RAID spans to implement the volume, each span comprising one or more of the coupled storage devices, at least one of the spans including a different number of drives than at least one other span.
