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.

Methods and systems for executing a decompressed portion of an option memory in a shadow memory. An area of system memory is allocated and a portion of the option memory is decompressed using the allocated area. The decompressed portion is stored in the shadow memory so the decompressed portion can be executed in shadow memory.

Methods and devices for decompressing and executing option memory for device in shadow memory of a computer system having a BIOS

A RAID level migration system and method are provided that enable RAID level migration to be performed without the use of a hardware RAID controller with NVRAM for storing the migration parameters. Eliminating the need for a hardware controller having NVRAM significantly reduces the costs associated with performing RAID level migration. The system and method are capable of migrating from any arbitrary RAID level to any other arbitrary RAID level.

Methods and associated structure to improve disk capacity utilization in the context of size coercion and COD space reservation techniques applied in a storage system. One aspect hereof provides that the size coercion computations to reduce (round down) the capacity of one or more disk drives in a storage system are performed prior to reservation of disk space for use in configuration-on-disk (COD) techniques. Performing coercion computations and configuration prior to COD space reservation prevents the COD reservation processing from causing un-necessary waste of physical capacity of the coerced disk drives.
