Abstract:
1. A disk layout method for object-based storage devices, the method comprising: initializing a disk; and adding a root object, a partition object, and a user object to the disk; wherein the root object includes attributes of the root object, a free block index table, and a partition object index table; the root object indexes a location of the partition object according to the partition object index table; the partition object includes attributes of the partition object, a collection object index table, and a user object index table; the partition object indexes a location of a collection object according to the collection object index table and a location of the user object according to the user object index table; the user object includes attributes and data of the user object; and each of the index tables is stored in at least one block set of the disk, two quantitative bytes in the first block of each block set are reserved, a first one of the two quantitative bytes represents a start location of a previous block set (SP) which is located before and stores the index table together with the block set having the two quantitative bytes, and a second one of the two quantitative byte represents a start location of a subsequent block set (SN) which is located after and stores the index table together with the block set having the two quantitative bytes.
