Abstract
A tape performance optimization method may include accumulating data in a memory, monitoring the accumulation of data, determining whether a certain amount of data has been accumulated in the memory, causing the accumulated data to be migrated to a tape in a tape library, and tracking physical locations of files stored on tape. In one embodiment, the amount of data to be accumulated is set to be two wraps or a multiple thereof. In one embodiment, two copies of data are written to two tapes in an alternating fashion. When a file is to be read, a tape is accessed if it has a copy of the file whose physical location is determined to be closest to beginning of tape. Since file location on tape determines the time it takes to position the tape, this method can shorten the amount of time required to retrieve a file from tape.
