Abstract: Mechanisms are provided, in a storage system controller of a storage system, for writing data to a storage medium. The storage system controller receives a write request to write a block of data to the storage medium. The write request does not specify a location on the storage medium to which to write the block of data. The storage system controller determines a current position of a write mechanism of the storage system relative to the storage medium and determines a location on the storage medium to write the block of data based on the current position of the write mechanism. The storage system controller sends a notification to a host system identifying the location of the block of data on the storage medium as determined by the storage system controller. The writing mechanism writes the block of data to the determined location on the storage medium.

Abstract: A tape recording device, method, and computer program product are provided for performing operations of position movement, reading, and writing on a tape medium, and receiving a series of commands from an upper-layer device. The tape recording device includes a buffer for temporarily storing data related to the reading and an append write, a tape for recording the data stored in the buffer, a reading and writing head for reading data from the tape into the buffer and writing the data onto the tape, control means for reading data from a designated position of the tape and storing the data in the buffer, and for writing the data stored in the buffer onto the tape from a written data end position in response to an append write command, and a non-volatile memory for storing data stored in the buffer in response to an append write command.

Abstract: A controller for controlling interrupt processing in a multiple-interrupt system is provided. The controller includes multiple watchdog timers (WDTs), each provided for each of interrupt priorities. The controller includes interrupt priority selectors, each of which receives each interrupt request signal and outputs an activation signal to a corresponding WDT according to the priority of the interrupt request signal. The controller includes an interrupt processing circuit, which when a WDT has timed out, outputs, to a processor, an interrupt request signal having a priority one or more levels higher than the priority corresponding to the WDT. When multiple causes of interrupt are assigned to one of the interrupt priorities, the interrupt processing circuit gives priority to an interrupt request signal caused by the timeout of a WDT lower in priority level than the interrupt priority to detect that an abnormal operation has occurred in interrupt processing having the lower level priority.

Abstract: An apparatus according to one embodiment includes a head, a controller coupled to the head, and logic integrated with and/or executable by the controller. The logic is configured to receive a series of commands, the series of commands including mixed read, overwrite, and append write commands, cause reading of data from a specified position of a tape using the head and storing the data in a buffer in response to a read command; and cause writing of data stored in the buffer starting from an appended data end position of the tape in response to an append write command.

Abstract: Provided is a method for recording data to a tape medium in such a manner as to achieve the easy management of mutually related multiple data pieces. First data and second data continuously received as a file from a higher level apparatus are accumulated in multiple buffer segments in the form of multiple successive data sets. A data structure is determined for each of the accumulated data sets. Management information indicating a result of the determination is added to the data sets, and the data sets and the management information thereof are stored into the tape medium.

Abstract: A method is provided according to one embodiment, which executes an optimum writing method even when overwrite is intervened between mixed read and write operations. In response to receiving an overwrite command while executing the mixed operations, which writes to a predetermined tape position, when a tape position to overwrite on is encountered before the append-written data ending position of the tape (tape EOD), the overwritten tape position is regarded as the append-written data ending position of the tape (tape EOD) to update the tape EOD by the overwritten tape position. When a tape position to overwrite is encountered after the append-written data ending position of the tape (tape EOD), the overwritten tape position is updated by the append-written data ending position of a non-volatile memory (non-volatile EOD). The updating the EODs enhances the performance of the mixed read and write operations even when an overwrite command is intervening.
