A storage system is disclosed that stores data across plural storage devices. The storage system includes plural modules. Each of the modules includes a storage device including a data storage section that has plural slice areas to store data elements one in each, and a control-information storage section that stores control information of the plural slice areas, a communications-function section having a function of sending and receiving the data elements stored in the slice areas in the data storage section. The modules communicate with each other to replicate the data element stored in the slice area into an unused slice area in another module so as to have data redundancy.

Storage system including a plurality of modules having different control information

In a distributed storage system, client terminals make access to virtual storage areas provided as logical segments of a storage volume. Those logical segments are associated with physical segments that serve as real data storage areas. A management data storage unit stores management data describing the association between such logical segments and physical segments. Upon receipt of access requests directed to a specific access range, a segment identification unit consults the management data to identify logical segments in the specified access range and their associated physical segments. A remapping unit subdivides the identified logical segments and physical segments into logical sub-segments and physical sub-segments, respectively, and remaps the logical sub-segments to the physical sub-segments according to a predetermined remapping algorithm. A data access unit executes the access requests based on the remapped logical sub-segments and physical sub-segments.

Computer program and method for balancing processing load in storage system, and apparatus for managing storage devices

A computer-readable, non-transitory medium stores the system analysis program which can accurately analyze the operational status of a system without modifying functions of the system for providing services. A message analysis unit analyzes the contents of collected messages, and determines the times of occurrence of the messages, the process types requested by the messages, and whether or not each of the messages is a request message or a response message. In response to an instruction for model generation, a model generation unit generates a transaction model satisfying at least one limiting condition related to caller-called relationships between processes, based on a set of messages selected in accordance with a selection criterion based on the certainty of existence of caller-called relationships. Then, in response to an instruction for analysis, an analysis unit analyzes the processing status of a transaction based on a protocol log conforming to the transaction model.

In a system management apparatus, a failure detection unit detects a readout failure in one of blocks constituting distributed data stored in a first RAID disk array. A request unit requests a computer to supplement one of the blocks of the distributed data stored in the first RAID disk array in which a readout failure irrecoverable by use of only the data stored in the first RAID disk array occurs, where the computer has a second RAID disk array storing a duplicate of the distributed data stored in the first RAID disk array. And an overwriting unit receives data corresponding to the one of the blocks from the computer, and overwrites the one of the blocks with the received data.

A storage management device includes a management unit for managing a storage device assigned thereto and a temporary storage unit assigned thereto. The management unit comprises a backup unit for, when data is written into the storage device, storing the data in the previously assigned temporary storage unit before the writing of the data into the storage device is completed, and a take-over unit for, when data which is already stored in the temporary storage unit, but which is not yet written into the storage device exists when the storage device and the temporary storage unit are assigned, writing the not-yet-written data into the storage device.

In a cluster system: a heartbeat transmission unit in a service provision node transmits to a monitoring node a heartbeat packet which contains interval information indicating an interval greater than normal intervals at which normal heartbeat packets are transmitted, when an execution unit in the service provision node receives a stop command. Thereafter, when software realizing the execution unit is updated and the execution unit is restarted, the heartbeat transmission unit periodically transmits the normal heartbeat packets to the monitoring node at the normal intervals, where the normal heartbeat packets contain interval information indicating the normal intervals. A heartbeat monitoring unit in the monitoring node determines that the execution unit is in operation, while the monitoring node receives heartbeat packets at intervals indicated by the interval information stored in the monitoring node and updated with received interval information.

A data allocation control program manages data allocation when data is distributively stored in a plurality of disk nodes that are shifted to a power saving mode unless access is performed for a certain time. The program produces a plurality of allocation pattern candidates each indicating the disk nodes in which the respective data are to be stored. The program calculates a no-access period expectation that represents an expected value of occurrence of a no-access period during which access is not performed to some of the disk nodes. The program selects as an allocation pattern for data reallocation, one of the plurality of produced allocation pattern candidates with the largest calculated no-access period expectation. The program instructs the disk nodes to reallocate the respective data in accordance with the selected allocation pattern.
