Abstract: A management system of a storage system specifies a matching rate between an occurred fault and each of one or more registered faults on the basis of fault analysis information which is information indicating, for each fault, a relation between a fault in the storage system and a fault detail including knowledge base information. Each of the one or more registered faults is a fault in which the information is registered in the fault analysis information. The management system displays information related to the registered fault including the specified matching rate with respect to each of the one or more registered faults.

Abstract: The present invention can shorten a response time required by a client computer to receive configuration information after transmitting a request for the configuration information to a storage system. A storage controller updates a plurality of pieces of configuration information based on control. A server computer transmits, to a storage controller, input information designating configuration information among the plurality of pieces of configuration information, according to a preconfigured schedule. The storage controller transmits output information including the configuration information inside the storage controller to a server computer based on the input information. The server computer receives output information, and stores the output information in association with the input information. Upon receipt of the input information from a client computer, the server computer transmits the output information associated with the received input information to the client computer.

Abstract: A storage system comprises multiple first storage apparatuses, and a controller which provides a first logical volume corresponding to a storage area of the multiple first storage apparatuses to a host computer. The controller partitions a storage area corresponding to the first logical volume into multiple first physical storage areas, manages the partitioned multiple first physical storage areas as physical storage areas of a storage pool, creates a first virtual volume which is provided to the host computer, and associates, from among the multiple first physical storage areas, a physical storage area in which user data is stored, with the first virtual volume.

Abstract: Events which have occurred in storage systems can be managed easily regardless of complexity of a storage configuration. An event notification system 1 includes: an event notifying client 133 for detecting the occurrence of an event(s) in volumes of a storage system 10; a management application server 20 for storing information about the occurred event as setting/failure information 21; and an event information aggregation server 30 for creating and managing event information 31 including an event key 311 for associating the occurred event with the setting/failure information 21. When the event information aggregation server 30 in such an event notification system 1 notifies an administrator terminal 50 of the event key 311 and an administrator selects the event key 311, the management application server 20 has the administrator terminal 50 display an event browse screen 52 indicating the relativity of a volume, in which the event occurred, to a volume in which a related event occurred.

Abstract: Multiple types of storage devices which have different performance are appropriately allocated to multiple virtual volumes in accordance with the performance requirements of the respective virtual volumes. In cases where, among virtual volumes 82 for which response times have been specified, there is a [virtual volume] that has a shortage of pages to which SSDs 70 should be allocated and that does not satisfy the performance requirement when its Tier boundary value ? is adjusted to Tier boundary value ?? and, if unallocated pages as the pages to which SSDs 70 should be allocated do not exist, Tier boundary value ? or Tier boundary value ? of another virtual volume is adjusted to Tier boundary value ?? or the Tier boundary value ??, and pages to which SSDs 70 are allocated are secured in the virtual volume 82 for which the Tier boundary value has been adjusted.

Abstract: This invention aims to optimize an entire storage system by equalizing the access counts in appropriate units. When migrating data in pool volumes to equalize the data access counts, which data migration—data migration in units of pages or data migration in units of volumes—is most appropriate is judged based on the information stored in an access information table storing access information, which is the information about the access counts for the data stored in the disk drives and, based on the judgment, data is migrated in units of pages or volumes so that the data access counts are equalized among groups. The data migration is repeated until the data access counts are equalized among the groups.

Abstract: Configuration information settings for a storage device are made highly reliable and facilitated. The storage device includes a service processor for setting storage device configuration information, and a terminal device connected to the service processor via a private line to send a command group, received from an operator and related to the storage device configuration information, to the service processor. The service processor also includes a device for determining approval or denial of execution of the command group prior to execution of the command group received from the terminal device.
