Paragraph Number

88

In another embodiment, the storage controller 152 emulates block storage by accepting block objects. A block object may include one or more data blocks in a block structure. In one embodiment, the storage controller 152 treats the block object as any other object. In another embodiment, an object may represent an entire block device, partition of a block device, or some other logical or physical sub-element of a block device including a track, sector, channel, and the like. Of particular note is the ability to remap a block device RAID group to an object supporting a different RAID construction such as progressive RAID. One skilled in the art will recognize other mappings of traditional or future block devices to objects.
