摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译：根据一个实施例提供了一种即使在混合读写操作之间进行覆盖时也执行最佳写入方法的方法。响应于在执行写入预定磁带位置的混合操作时接收到重写命令，当在磁带（磁带EOD）的附加写入的数据结束位置之前遇到要重写的磁带位置时，重写磁带位置被视为磁带（磁带EOD）的附加写入数据结束位置，以通过重写磁带位置来更新磁带EOD。当在磁带（磁带EOD）的附加写入的数据结束位置之后遇到要重写的磁带位置时，通过非易失性存储器（非易失性EOD）的附加写入的数据结束位置来更新重写磁带位置，。更新EOD可增强混合读写操作的性能，即使在覆盖命令中也是如此。
