摘要： According to an aspect of the embodiment, a packet analyzing apparatus monitors a concentration level of input and output access from an access apparatus to a disk device, specifies a data area to which the concentration level of input and output access exceeds a first threshold, and instructs a storage server to cache the data area. The packet analyzing apparatus monitors a concentration level of input and output access to a data area to which the data area is cached, and, when the concentration level of input and output access is below a second threshold, instructs the storage server to release the caching.

摘要： A computer in a disk node executes a data management program. A deduplication-eligible data unit detection module detects a data unit whose deduplication grace period after last write time has expired. A deduplication address fetch module interacts with an index server to obtain a deduplication address associated with a unique value of data stored in a constituent storage space allocated to the data unit that is found to be deduplication-eligible. A constituent storage space deallocation module stores the obtained deduplication address in a data unit record memory, together with information indicating the detected data unit. Simultaneously a constituent storage space deallocation module releases the allocated constituent storage space from the detected data unit.

摘要： An allocation control apparatus may access an address table storing addresses of slice areas allocated in a storage area for an entire storage system having a plurality of storage devices and addresses that do not correspond to allocated slice areas. The allocation control apparatus includes a reception unit receiving a request for allocating an arbitrary storage capacity an allocation unit allocating, by referring to the address table, an address that does not correspond to the allocated slice area for at least a part of the requested storage capacity and allocates an address for the slice area to the remaining storage capacity when the reception unit receives the allocation request, and a transmission unit transmitting the result allocated by the allocation unit to a requesting source of the allocation request.

摘要： Processing time required from transmission of a request packet including a processing request from a client, until return of a reply packet in which internal information including an operation status of a plurality of servers is added to an execution result of processing corresponding to the processing request, obtained by the servers in cooperation with each other, is calculated by a function incorporated beforehand in the respective servers. Moreover, the internal information added to the reply packet is extracted and stored in an internal information DB in association with the calculated required time of the processing. Furthermore predetermined statistical processing is performed with respect to the internal information and the required time associated with the internal information stored in the internal information DB to analyze the operation status of the plurality of servers.

摘要： A computer-readable medium storing a data management program makes a computer manage data redundantly stored in storage devices having storage areas split into slices for data management. The data management program realizes the following functions in the computer. A first function receives irregularity information indicating that each of one or more of the storage devices may be possibly faulty, and stores the irregularity information in a storage; and a second function determines, by reference to the irregularity information, whether or not a first storage device containing a slice to be accessed is possibly faulty, on receipt of access information indicating occurrence of a request to access the slice. When yes is determined, the second function instructs an external device to recover data stored in the slice, where the external device controls a second storage device storing redundant data identical to the data stored in the slice.

摘要： An allocation control apparatus allocates duplicate logical volume divided areas to virtual storage areas that do not have data storage area in the physical storage area. The apparatus associates identification information of the allocated virtual storage areas, of the duplicate logical volume divided areas, and of duplication source logical volume divided areas to be set in the management information. The apparatus detects, upon a data writing request, based on the management information, the unallocated real storage area in the logical volume divided area. The apparatus reallocates the real storage area to the duplicate logical volume divided area to update the management information. The apparatus identifies, based on the management information, the real storage area allocated to the duplication source logical volume divided area corresponding to the duplicate logical volume divided area. The apparatus copies data stored in the real storage area to the real storage area.
