摘要： An information system connected to hosts and an information processing system manages a second ALU connected to the hosts via a second logical path, and second SLUs for receiving I/O requests from the hosts via the second logical path. A processor manages a first ALU connected to the hosts via a first logical path and first SLUs that receive I/O requests from the hosts via the first logical path, and builds up a first group including the first SLUs. A first SLU and a second SLU compose an HA pair, and the HA pair is provided to the hosts as one volume. The processor evaluates the state of the first logical path based on the pair state of the first SLU that composes the HA pair included in the first group so priorities with which the hosts issue I/Os to the first logical path can be determined.

摘要： Saving a capacity of an on-premises storage apparatus, a high access performance of the on-premises storage apparatus, and resuming an operation quickly and accurately by using data on a cloud when a resource in the on-premises fails are achieved.A processor provides a first volume which is a virtual volume, and configures a copy pair of the first volume and a second volume provided from another storage system. Write data to the first volume is transferred to the second volume via a network, based on the copy pair. The processor writes to the memory a part of data written to the second volume, and writes to the storage device the data written to the memory.

摘要： In an exemplary storage system, a processor assigns an unused process to a read request designating an area of a logical volume. The processor determines whether the data designated by the read request is in a cache memory, based on a first identifier for identifying the area designated by the read request. When the designated data is not in the cache memory and a part of physical volumes providing the logical volume is a first kind of physical volume, the processor stores the first identifier associated with an identifier for identifying an area allocated in the cache memory. When the designated data is not in the cache memory and a part of the physical volumes is a second kind of physical volume, the processor stores a second identifier for identifying the process assigned to the read request associated with an identifier for identifying an area allocated in the cache memory.

摘要： An information processing system includes storage apparatuses installed in areas, SDSs provided on a cloud, and a management system. The management system estimates, in reference to configuration information and performance information regarding a volume of each of the storage apparatuses, a required resource amount required to fail over the volume of each storage apparatus to a duplicate volume. The management system selects an SDS of a replication destination in such a manner as to minimize a required resource amount aggregated for each installation location and for each storage system SDS, while locating in a distributed manner, in the SDSs, duplicate volumes related to the storage apparatuses located at an identical point.

摘要： A processor repeatedly collects integrated management information related to a storage apparatus and including performance data indicating an operation status of the storage apparatus that stores data, and stores the performance data in an performance data temporary storage area. In addition, the processor analyzes the integrated management information, and determines the importance level indicating the degree of the influence of the performance data stored in the performance data temporary storage area on the analysis process of analyzing the performance data. The processor migrates the performance data stored in the performance data temporary storage area to one of the plurality of long-term storage areas having different characteristics based on the importance level.

摘要： A first storage system compresses data relating to read and write by a primary site and stores the data in a first physical volume. A second storage system compresses data relating to read and write by a secondary site and stores the data in a second physical volume. When performing replication for transferring the data stored in the first physical volume of the first storage system to the second storage system and storing the data in the second physical volume, the first storage system and the second storage system determine, based on a compression scheme executable by the first storage system and a compression scheme executable by the second storage system, a compression scheme to be applied to transfer target data and transfer the transfer target data compressed by the determined compression scheme.

摘要： To be able to support the efficient handling of problems during maintenance. A management board determines an accomplishment sequence of handling manipulation for failures on a maintenance target. The management board includes a CPU, memory, and a storage device. The memory or the storage device stores: condition information associating the handling manipulation with a condition concerning at least accomplishment or non-accomplishment of the manipulation; and failure handling information that associates a failure occurring on the maintenance target with the handling manipulation. The CPU is configured to determine the accomplishment sequence of the handling manipulations so that multiple handling manipulations for multiple failures occurring on the maintenance target satisfy the condition.
