Abstract
Available storage locations are identified by searching through a free blocks object non-sequentially. The free blocks object may be logically divided into sections, and the sections may be searched non-sequentially. Each section may be logically divided into a number of sub-sections, and the sub-sections of the various sections may be searched non-sequentially. A new section may be added to the free blocks object, and the added section may be searched until a predetermined threshold or condition is reached, at which point non-sequential searching may begin or resume.
