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 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.
摘要翻译：本地站点中的控制器可以处理来自主机，备份服务器和层管理器等请求者的存储资源请求。控制器根据要求根据要求，对本地站点内存储资源信息进行自我检查。控制器还要求远程站点中的其他控制器检查每个远程站点中的存储资源。本地控制器根据要求收集有关可用存储资源（包括本地站点资源）的答案，并选择要使用的存储资源。然后本地站点的控制器通知选定的存储资源给请求者。存储资源的释放也可以通过控制器之间的通信进行。计算机和备份服务器可以利用控制器提供的这些功能来获取和释放存储资源。

摘要： A plurality of storages having respective attributes and a method for preserving data is provided in consideration of the attribute (performance or cost) and the operation ratio of the storage and the using frequency of the data in the storage area network. The information processing system of the invention includes a location management unit for managing a location of the data stored in the storage, an information duplication unit for duplicating the data between the storages, and an attribute preservation unit for preserving information for representing the attribute of each storage. The location management unit duplicates and moves the data between the storages by using the information duplication unit, based on the operation ratio of the storage, the access frequency of the data, the control information and the billing information.

摘要： In a disk array system, data read out and data written anew are temporarily held as former data in a former data holding portion. When a write operation has occurred, a CPU searches the holding portion for write data, it generates update data from the new and former write data items, and it holds the generated update data in an update data holding portion. In addition, the CPU stores the storage address of redundant data associated with the held update data, as log data in a log data holding portion. Further, the CPU operates asynchronously with the write operation to read out the redundant data of the address of the holding portion, to calculate new redundant data from the read redundant data and the held update data, and to write the new redundant data into the address of the log data. On this occasion, a parity area and a data area are separated so as to heighten read/write processing speeds and a parity generation processing speed.

摘要翻译：在磁盘阵列系统中，数据读出和重新写入的数据被暂时保持为前一数据保存部分中的前一数据。当发生写入操作时，CPU在保持部分中搜索写入数据，它从新的和先前的写入数据项生成更新数据，并且将生成的更新数据保存在更新数据保存部分中。此外，CPU将与所保持的更新数据相关联的冗余数据的存储地址作为日志数据存储在日志数据保持部分中。此外，CPU与写入操作异步地读出保持部分的地址的冗余数据，从读取的冗余数据和保持的更新数据计算新的冗余数据，并将新的冗余数据写入地址的日志数据。在这种情况下，分离奇偶校验区域和数据区域，以便提高读/写处理速度和奇偶校验生成处理速度。

摘要： Exemplary embodiments establish durable partitions that are unified across storage systems and storage server computers. The partitions provide independent name spaces and are able to maintain specified services and conditions regardless of operations taking place in other partitions, and regardless of configuration changes in the information system. A management computer manages and assigns resources and functions provided by storage server computers and storage systems to each partition. By using the assigned resources, a partition is able to provide storage and other services to users and applications on host computers. When a configuration change occurs, such as addition or deletion of equipment, the management computer performs reassignment of resources, manages migration of services and/or data, and otherwise maintains the functionality of the partition for the user or application. Additionally, a partition can be migrated within the information system for various purposes, such as improved performance, load balancing, and the like.

摘要： A storage system comprises one or more pool volumes having chunks for storing data; one or more primary volumes; writable snapshots as virtual volumes for each primary volume which is a common ancestor of the writable snapshots, each primary volume and corresponding writable snapshots being members forming a snapshot group; and a storage controller which includes a processor, a memory storing, for each snapshot group, group information of the members within the snapshot group, and a deduplication module. The deduplication module may identify a snapshot group for deduplication based on the group information and perform deduplication of data for the identified snapshot group in a deduplication area, or perform deduplication of data in a deduplication area which is specified based on the group information of a snapshot group being generated in the storage system.

摘要： In a computer system having a host system including a plurality of disk devices, a CPU, a main memory and a disk control circuit for controlling the disk devices, a host CPU executes a program unit to generate intermediate data for parity generation and holds it in a data holding unit to asynchronously conduct a data write process and a parity write process. A unit for generating parity and a unit for transferring data operate without the intervention of the CPU in accordance with a command issued by the program unit executed by the host CPU.

摘要： A computer system which includes a host machine having a memory and a CPU with an interrupt handling feature, an auxiliary memory unit for recording and reproducing data and an input/output unit for permitting data input and output between the host machine and the auxiliary memory unit. The CPU of the host machine generates a plurality of commands for designating access to the auxiliary unit, in response to at least one command, groups a plurality of the commands for designating access to the auxiliary memory unit, into at least one group and supplies the input/output unit with the commands independently of one another. The input/output unit executes access to the auxiliary memory unit as designated by each of the commands of one group supplied independently of one another by the CPU, and notifies the CPU by a single interruption that execution of the commands of the one group has been terminated when the accesses designated by all commands belonging to the one group have been terminated.
