Abstract
The disclosure provides instantaneous, vertical online capacity expansion (OCE) for redundant (e.g., RAID-5, RAID-6) and non-redundant (e.g., RAID-0) arrays. The new OCE technique implements vertical expansion instead of the horizontal expansion techniques implemented in current OCE techniques. The vertical expansion treats any new addition of storage as an extension of the capacity of the preexisting physical drives in order to avoid having to rewrite the data blocks of the original, preexisting storage devices. Vertical RAID expansion is implemented by installing one or more new physical storage devices in a device or partition configuration that corresponds to the physical configuration of the preexisting volume and loading new metadata received through the user interface into the firmware of the RAID controller to define the configuration of the expanded volume.
