A subsystem logics partitioning and managing apparatus comprises a recognition unit for recognizing logical and physical resources that constitute a subsystem a partition definition table in which the logical and physical resources in the subsystem are assigned for each user at an interface level at which a storage configuration can be referenced by a storage management program an account table in which an account is set for each user-specific partition defined in the partition definition table a receiving unit for receiving a user account transmitted from an information processing unit and checking the received user account against the account table, to recognize a partition that corresponds to the user and a unit for outputting, at a GUI level, logical resources and physical resources that are contained in the recognized partition to an output interface as a resource configuration in the subsystem.

A storage management apparatus performs migration considering an I / O load that will be generated during migration between a source array group and a destination array group. To migrate data from the source array group to the destination array group, a bandwidth that is available for use between the source and destination array groups is calculated. A volume that is within the source array group, and that has a write I / O amount that is smaller than the calculated bandwidth, is selected as the source volume for the migration, wherein the write I / O amount is the information transmission amount of information that is written. Data is thus migrated from the selected volume to the movement destination array group.

A storage management process and a storage management apparatus for managing first data stored in a storage area in a storage device in a first one of storage nodes constituting a distributed storage system. The first data is read out from the storage device and checked for normality in response to a request. When the first data is abnormal, a second one of the storage nodes paired with the first one is determined by reference to management information which is stored in advance, and second data which is identical to the first data and managed by the second one of the storage nodes is acquired. Then, the storage area is overwritten with the acquired second data when the first data is abnormal.

A subsystem logics partitioning and managing apparatus comprises a recognition unit for recognizing logical and physical resources that constitute a subsystem a partition definition table in which the logical and physical resources in the subsystem are assigned for each user at an interface level at which a storage configuration can be referenced by a storage management program an account table in which an account is set for each user-specific partition defined in the partition definition table a receiving unit for receiving a user account transmitted from an information processing unit and checking the received user account against the account table, to recognize a partition that corresponds to the user and a unit for outputting, at a GUI level, logical resources and physical resources that are contained in the recognized partition to an output interface as a resource configuration in the subsystem.

The information processing apparatus includes: a connection unit which an electronic apparatus is adapted to be communicably coupled to; a connection detecting unit which detects coupling of the electronic apparatus to the connection unit; a timer which measures a time duration that elapses under a connection state, in which the electronic apparatus is engaged; and an alerting unit which alerts a user of the information processing apparatus when it is detected by the timer that a predetermined time duration elapses. With this arrangement, it is possible to prevent forgetting to disengage the electronic apparatus from the information processing apparatus, and the convenience of handling of the electronic apparatuses is improved.

A method for managing multiple nodes hosting multiple memory segments, including: identifying a failure of a first node hosting a first memory segment storing a hypervisor; identifying a second memory segment storing a shadow of the hypervisor and hosted by a second node; intercepting, after the failure, a hypervisor access request (HAR) generated by a core of a third node and comprising a physical memory address comprising multiple node identification (ID) bits identifying the first node; modifying the multiple node ID bits of the physical memory address to identify the second node; and accessing a location in the shadow of the hypervisor specified by the physical address of the HAR after the multiple node ID bits are modified.

A user operates an input device to set information necessary for reserving a volume and a port while looking at a screen for reservation management displayed on a display device Next, a storage management program retrieves reservable volumes and ports using a volume retrieval subprogram of a policy basis. At this point, when a policy concerning performance is inputted, the storage management program inquires of a performance analysis program of a storage performance management server whether the performance is satisfied. When the volume and the port are found, the storage management program stores reservation information in a reservation management DB using a reservation subprogram. When the volume and the port are not found, the storage management program judges whether an alternative volume for the reserved volume is present using a volume adjustment subprogram.

A subsystem logics partitioning and managing apparatus comprises a recognition unit for recognizing logical and physical resources that constitute a subsystem a partition definition table in which the logical and physical resources in the subsystem are assigned for each user at an interface level at which a storage configuration can be referenced by a storage management program an account table in which an account is set for each user-specific partition defined in the partition definition table a receiving unit for receiving a user account transmitted from an information processing unit and checking the received user account against the account table, to recognize a partition that corresponds to the user and a unit for outputting, at a GUI level, logical resources and physical resources that are contained in the recognized partition to an output interface as a resource configuration in the subsystem.

The system is composed of the storage apparatuses with dynamic chunk allocation capabilities, the centralized management computer. Some storage apparatuses have the extra HDDs or volumes for providing extra capacity (extra chunks), which are concealed by a secret key. The storage apparatus with the closed segment has the key management program and key management table. The centralized management computer has the storage on demand management program, the pending request table, the priority table and the master key table. The storage apparatus may connect to the other storage apparatuses for sharing the extra capacities in the closed segment. The storage apparatus issues the chunk addition request to the centralized management computer. The centralized management computer provides a key according to the priority table and the master key table. The centralized management computer may provide the key according to the chunk consumption rate reported by the storage apparatus and / or remaining capacity in the other storage apparatuses.
