摘要： A system and method for object-level snapshot creation in an object-based storage system. The host device includes a first object management table (OMT) and a file system. The object-based storage system is connected to the host device and includes a controller and object-based storage devices (OSD). The controller includes a snapshot module, a second OMT. The snapshot module receives and processes OSD and other commands from the file system or a service processor, creates an original object and a mirror object in an OSD, and initiates a snapshot operation in an OSD. The first OMT may also reside at a metadata server. A snapshot operation may be a mirror operation or a copy on write operation. The first OMT and the second OMT maintain mapping information of a file identifier, a partition ID, and an object ID, and an object status and a generation number of snapshots.

摘要： An apparatus, system, and method enable access to a storage system by distinguishing SCSI Object-Based Storage Device Commands (OSD) commands from Fibre Channel (FC) SCSI commands on the same port and storage subsystem. The storage subsystem has the capability of identifying the storage protocol from a corresponding command, and processes the command accordingly for a storage device formatted for use with the respective storage protocol. This way, a storage subsystem can consolidate data from several dedicated command ports to a single physical port, while also enabling a single storage system to store and provide access to data in multiple different storage protocol formats.
摘要翻译：设备，系统和方法通过在相同的端口和存储子系统上区分来自光纤通道（FC）SCSI命令的基于SCSI对象的存储设备命令（OSD）命令来实现对存储系统的访问。存储子系统具有从对应命令中识别存储协议的能力，并相应地处理用于与各自存储协议一起使用的格式化的存储设备的命令。这样一来，存储子系统就可以将数据从多个专用命令端口合并到单个物理端口，同时还可以使单个存储系统存储和提供对多种不同存储协议格式的数据的访问。

摘要： The system is disclosed in which a storage system having data, and meta-data which describes attributes of the data including its address, can copy the data to a secondary system in a more efficient manner. The storage system identifies the blocks which contain the data described in the meta-data, then reads those blocks in the order of their addresses and copies them to the desired target. The method reduces disk access time and thereby speeds copy operations.

摘要： A method of generating and linking programs required in a data linkage system to link data among a plurality of computer systems, for example a mainframe and an open system, is provided. In the data linkage system with a means for data transfer via a storage device, a program generation tool is prepared in the open system. The program generation tool reads a data stream definition and generates an intermediate file area securing program and a data linkage program A, both run on the mainframe, and a data linkage program B run on the open system. These programs are linked with one another. The intermediate file area securing program and the data linkage program A are transferred to the mainframe where they are executed.

摘要： An information system which includes a primary storage system, a host, an external storage system, and a management host. Each storage system may be a different from the other storage system. The primary storage system treats logical devices in the external storage system as if they were logical devices in the primary storage system. When a disk that forms a part of a logical device in the external storage systems fails, the management host detects the failure and judges whether the logical device is used by the primary storage system to form a virtual device. If the logical device is used to form a virtual device, then the management host issues a migration request to the primary storage system. In response to the migration request, the primary storage system migrates data from the failed logical device to a logical device in the primary storage system to avoid data loss.

摘要： A system for managing clock adjustment in a storage system is provided. The system includes a clock configured to provide a current time, wherein the current time is used to enforce a content retention period, a memory configured to store clock management information, wherein the clock management information includes a last adjustment time and a number of maximum adjustable time ranges, wherein the last adjustment time represents the time which the clock was last adjusted, and a storage access program. The storage access program is configured to receive a proposed new time for the clock, determine whether the proposed new time is reasonable using the current time, the last adjustment time and a specific range selected from the maximum adjustable time ranges, and adjust the current time of the clock to the proposed new time if it is determined that the proposed new time is reasonable. The storage access program is further configured to prevent adjustment of the clock to the proposed new time if it is determined that the proposed new time is unreasonable.

摘要： A standard physical medium 1320 as loaded into library unit 1080 even in the absence of any load request from a host computer 1020 is regarded as a spare physical medium 1330 for use when the standard physical medium 1320 is under malfunction, and such medium is put in a spare media storage space 1340 while eliminating issuance of any notice to the host computer 1020. Whereby, in a computer system with redundancy configuration, it becomes possible to prevent the host computer from making use of any spare physical media.
摘要翻译：即使在没有来自主计算机1020的任何负载请求的情况下，加载到库单元1080中的标准物理介质1320被认为是当标准物理介质1320处于故障状态时使用的备用物理介质1330，并且将这样的介质放入备用介质存储空间1340，同时消除对主计算机1020的任何通知的发布。因此，在具有冗余配置的计算机系统中，可以防止主机使用任何备用物理介质。
