    摘要： Provided are a computer program product, system, and method for synchronous mode replication to multiple clusters receiving a write to a volume from a host. A received write is cached in a memory. A determination is made of a replication rule indicating one of a plurality of replication modes for a first cluster and a second cluster used for replication for the write, wherein one of the replication modes comprises a synchronous mode. A determination is made that the replication rule indicates a synchronous mode for the first and the second clusters. The write is transmitted from the memory to the first cluster to store in a first non-volatile storage of the first cluster and to the second cluster to store in a second non-volatile storage in response to determining that the replication rule indicates the synchronous mode.

    摘要： A tape recording apparatus is configured for sequentially recording files when receiving a command to write the files from an external host. The tape recording apparatus includes a buffer for temporarily storing the files, a tape on which the files are recorded, a writing device for writing the files stored in the buffer on the tape, and a writing control device for performing control of sequentially writing the files stored in the buffer on the tape one by one. The writing control device memorizes designated delimiter positions when delimiter position designation commands are received from the external host, the delimiter position designation commands designating the delimiter positions of the files to be sequentially written.

    摘要： Systems and methods for managing a virtual tape library (VTL) domain capable of being coupled to a host are provided. One system includes a plurality of VTL nodes configured to store multiple scratch erased volumes. Each VTL node comprises a processor configured to perform at least a portion of the below method. One method includes receiving a request from the host to de-mount a volume in one of the plurality of VTL nodes, transferring the volume to a scratch category in response to receiving the request, erasing data in the volume and categorizing the volume as a scratch erased volume, and providing ownership of the scratch erased volume to a VTL node in the plurality of VTL nodes based on pre-determined criteria for the plurality of VTL nodes. Also provided are computer storage mediums including computer code for performing the above method.
