摘要： A computer-implemented metadata processing method and a system includes writing metadata to or reading metadata from a storage medium in which an index that contains metadata of each of one or more pieces of data is stored. The method and system include determining, in response to a processing request, which includes a write request or a read request, when to communicate with a storage area outside the index. At least a portion of content of the metadata relating to the processing request is processed, and accessed, including storing or obtaining, in the index, location information indicating the storage area of the portion of content of the metadata.

摘要： A first data group in an access sequence is selected. Those data groups located in specified regions of the tape medium are separated from other data groups located in alternative specified regions of the tape medium. The distance from the current position of the tape medium is set to be a logical distance value, determined by a calculation function, that is substituted for the physical distance value for the data groups that are located in the specified regions as compared with other data groups located in the alternative specified regions. A second data group in the access sequence is selected. The logical distance value is then determined by multiplying a coefficient based on a physical positioning of each of the data groups in the tape medium, and a percentage of those of the plurality of data groups that have already been selected as the first data group and the second data group.

摘要： A method for writing a file from an application of a host onto a tape includes sequentially receiving records forming the file from the application, adding a predetermined number of segments of dummy data (dummy records) subsequently to the plurality of records forming the file such that the records of the file and records of a subsequent file are not included in the same data set, interposing the dummy records between a final record of the file and a head record of the subsequent (next) file, to thereby construct at least one data set that is adjacent to one data set and does not include the records of the file, and writing a data set including the records of the file, a data set (dummy data set) including the final record of the file and the dummy records, and a data set including the subsequent file, onto the tape.

摘要： An apparatus, computer readable medium device, and method for controlling transportation of a tape medium. A determination is made whether to execute a backhitch operation in response to writing a data set to tape from the buffer. If not, a determination is made whether a transaction size at which data is transferred from the buffer to the tape is less than a buffer size. If so, then a determination is made of a a new speed and whether a current speed is different from the determined new speed. If so, then a backhitch is initiated.

摘要： A method for writing data in a buffer to a magnetic recording tape includes identifying a size of an unused area of the magnetic recording tape based on a current writing position on the magnetic recording tape. An upper limit of a capacity for data that can be stored in the buffer is determined based on the size of the unused area. The predetermined data is stored, according to a command for storing predetermined data in the buffer, in the buffer on condition that the capacity for data in the buffer does not exceed the upper limit.

摘要： To provide a technique for optimizing the processing order of recall requests in which the average latency time of a host apparatus is minimized. A storage manager accepts a request of the host apparatus for the recalling data from a tape library, and stores the request in a queue table. In response to storage of the request, the storage manager calculates the latency time for each request in all the conceivable execution orders for all the requests stored in the queue table. The storage manager determines the execution order which minimizes the total calculated latency time for all the requests including the active request, and rearranges the requests in the queue table.
