摘要： A method of utilizing storage in a storage system comprises prioritizing a plurality of storage areas in the storage system for data recovery with different priorities; and performing data recovery of the storage system at an occurrence of a failure involving one or more of the storage areas in the storage system based on the priorities. Data recovery for one storage area having a higher priority is to occur before data recovery for another storage area having a lower priority in the storage system. In various embodiments, the prioritization is achieved by monitoring the access characteristics, or the priority is specified by the host or management computer based on the usage and/or importance of data stored in the storage system, or the priority is determined by the storage system based on the area assignment/release (i.e., usage) of thin provisioned volumes.

摘要： A sorting system includes a plurality of input nodes, each of which sorts sorting target data distributed and stored in input local disks. An internally sorted result is stored as a plurality of sorted strings in a shared disk connected between the input node and output node. Upon reception of a merge instruction from all input nodes, the output node reads the sorted string from the shared disk and merges it and outputs a whole sorted result of all input data to an output local disk. In a process of obtaining a whole sorted result of all input data through parallel processing by a computer system constituted of a plurality of computers (nodes), a time to sorting input data can be shortened.
摘要翻译：排序系统包括多个输入节点，每个输入节点对分发并存储在输入的本地盘中的目标数据进行排序。内部排序结果作为多个排序的字符串存储在连接在输入节点和输出节点之间的共享盘中。在从所有输入节点接收到合并指令时，输出节点从共享磁盘读取排序的字符串并将其合并，并将所有输入数据的整体排序结果输出到输出本地磁盘。在通过由多个计算机（节点）构成的计算机系统的并行处理来获得所有输入数据的整体排序结果的过程中，可以缩短排序输入数据的时间。

摘要： Disclosed is a system incorporating a management computer, host computers, a backup server and at least one storage system. Backup data generated in the system are stored in various storage system such as disk array, tape library and VTL (virtual tape library) with various methods such as continuous data protection and snapshot, and management information of the backup data is maintained by the management computer. The management computer conducts transition of mode of the backup data by detecting that a condition to perform the transition is satisfied, determining a plan of transition according to predetermined scenario, performing (instructing) the transition based on the plan and updating the management information of the backup data. By keeping the management information up to date, the management computer can provide a unified means to restore necessary data from the backup data even if the transition (moving and/or change) of the backup data has been performed.

摘要： A controller in local site can process a request for storage resources from requestors like host computers, backup servers and tier manager. The controller checks own resource information including information about storage resources in the local site, according to requirements based on the request. The controller also asks other controllers in remote sites to check storage resources in each remote site. The controller in the local site collects the answers about available storage resources (including resources in the local site) under the requirements and selects storage resources to be used. Then the controller in the local site notifies the selected storage resources to the requester. Release of storage resource can also be performed with communication between controllers. Computers and backup servers can utilize these functions provided by the controllers to obtain and release the storage resources.

摘要： In a storage system implementing journaling for data backup and restore, users are able to easily determine information regarding amounts journal data generated over specified periods of time. Flexible and automatic adjustment of the journal area is enabled by providing the user with the information on the relationships between the amounts of journal data generated over periods of time. Also dynamic allocation of storage capacity from free space may be applied to the journal volume on an as-needed basis, and may be used to minimize the size of the journal volume when certain journal entries are determined to be no longer needed. Thus, users are able to determine an appropriate size of a journal area in accordance with requirements for predetermined preservation periods for backup data. Thereby, management of the journal area is simplified and the costs to manage the journal area are reduced.

摘要： Information about management of virtualization (i.e. mapping between physical area/data/objects and logical area/data/objects) is provided by a storage system to a backup appliance (or common computer) that performs backup and restore of data. The backup appliance uses the information to recognize the mapping and to perform backup and restore process based on the mapping. Therefore the backup appliance handles only physical (really existing) area/data/objects to perform backup and restore rather than virtual ones. This realizes reducing the amount of data to be transferred and backed up, thus the problems mentioned above are solved.
摘要翻译：有关虚拟化管理（即物理区域/数据/对象与逻辑区域/数据/对象之间的映射）的信息由存储系统提供给执行数据备份和还原的备份设备（或公用计算机）。备份设备使用该信息来识别映射，并根据映射执行备份和恢复过程。因此，备份设备只处理物理（真正存在的）区域/数据/对象来执行备份和恢复，而不是虚拟的。这实现了减少要传输和备份的数据量，从而解决了上述问题。

摘要： A cache package (for example, a flash memory package configured by flash memories) can execute a cache control process instead of a processor in a storage system by a request of the cache control process from the storage system. Consequently, time for the process that the processor of the storage system executes can be reduced and increase in a throughput can be achieved. For example, particularly the present invention is effective in real time data processing in OLTP (OnLine Transaction Processing) (for example, database processes in finance, medical service, Internet service, and government and public service). In addition, under the concept of recent EPR (Enterprise Resource Planning) a flexible storage system that can respond rapid fluctuation in an amount of data and an access load can be established and leveraged by increasing several boards of required cache packages.
