Abstract
A method is described. The method includes constructing a bitmap having a first dimension organized into bins of logical block addresses (LBA bins) and a second dimension organized into bins of physical block addresses (PBA bins). Coordinates of the bitmap indicate whether respective physical blocks of non volatile memory within one or more SSDs that fall within a particular PBA bin are being mapped to by an LBA that falls within a particular one of the LBA bins. The method includes using the bitmap during a rebuild of an LBA bin of an LBA/PBA table to avoid reading meta data for physical blocks that are not mapped to by an LBA that falls within the LBA bin.
