  • Optimization of rebuilding in solid state drives
    Patent number: 9940198
    Abstract: A data processing apparatus-implemented method, according to one embodiment, includes selecting blocks of data in at least one solid state drive for garbage collection in a garbage collection process, and creating a bitmap indicating which blocks of data are in the garbage collection process. The bitmap has a two bit structure for each of the blocks, where the two bit structure includes a unique pair of bits associated with a logical block address (LBA) of the individual one of the blocks associated with the two bit structure. One bit indicates whether the block is in the garbage collection process. The other bit indicates whether rebuilding of the block has been completed.
    Type: Grant

  • Optimization of rebuilding in solid state drives
    Patent number: 9658923
    Abstract: According to one embodiment, a method includes initiating a rebuild process in a storage system having at least one solid state drive, obtaining a bitmap indicating which blocks of data are in a garbage collection process, determining which blocks of data are in the garbage collection process using the bitmap, accessing the blocks of data that are not in the garbage collection process, not accessing the blocks of data that are in the garbage collection process, and performing the rebuild process using the blocks of data that are not in the garbage collection process.
