Method and system for minimizing seek affinity and enhancing write sensitivity in a DASD array

摘要: A method and system for minimizing seek affinity enhancing write sensitivity in a direct access storage device (DASD) array are disclosed. SEEK WRITE efficiency preserved which logical cylinders, as recorded on the DASD array, managed individual log structured files (LSF). Tracks or segments of data parity blocks having same different group stored cylindrical addresses written into directory buffer. Blocks to counterpart cylinders out from buffer spare space reserved part each cylinder. Otherwise, updated place their location.
