Each of the zones is a contiguous physical address range of the storage device that is mapped to a contiguous logical address range. The processor is configured to generate zone management information for each of the plurality of zones, store content received from the origin server via the network interface, in one of writable zones and update a writable address of the zone management information for the one of the writable zones. The processor is configured to operate to transmit the received content, and control the storage device to delete data stored therein in units of a zone upon a predetermined cache clearing criteria being met.

Information processing apparatus and method

According to one embodiment, a control device includes one or more processors. The one or more processors receive a message. The one or more processors determine whether the received message has been replicated and transmitted. The one or more processors instruct recording of difference information between a message before replication and the received message when it is determined that the received message has been replicated and transmitted.

Control device, control method, computer program product, and communication system

In a data transfer device that communicates with a communication device via a network, the storage controller controls reading data from and writing data to a plurality of storages. The correspondence information manager manages correspondence information manager to manage correspondence information between data written by the storage controller and a storage to which the data is written. The storage manager manages an invalid storage being a storage that the storage controller failed to read or write data. The communicator receives an acquisition request message for data from the communication device. The specifier specifies a storage storing the data requested, according to the correspondence information. The reader requests the storage controller to read the data from the storage specified by the specifier when the storage does is not the invalid storage, and not to request the storage controller to read the data when the storage is the invalid storage.

Data transfer device, data transfer method, and non-transitory computer readable medium

The data transfer device receives file data through a network and writes the file data to a storage device on a block basis, in which the communication processor receives a receiving instruction for the file data from an external host CPU and receives the file data via one or more packets from the network according to the receiving instruction, the receiving buffer stores data received in the communication processor therein upon receiving each packet, and the command issuance controller acquires, from the external host CPU, map information indicating a position to write the file data in a storage area of the storage device, specifies data in the receiving buffer for writing according to a data storing status of the receiving buffer, issues a write command for writing a specified data to the storage device and sends it to the storage device.

Data transfer device, data receiving system and data receiving method

According to one embodiment, a relay apparatus is connectable to a server and a plurality of storage devices. The relay apparatus includes a storage unit, a transfer destination management unit, and a transfer unit. The storage unit stores first information including information of the plurality of storage devices therein. The transfer destination management unit identifies a first storage device among the plurality of storage devices based on the first information in response to receiving a request from the server. The transfer unit transfers the received request to the first storage device.

Relay apparatus

According to an embodiment, a storage device includes an acquisition unit, a first generation unit, and an erase unit. The acquisition unit is configured to acquire erase permission notification which is generated based on specific data and first authentication information to authenticate the specific data, and includes a first erase code to erase the specific data and physical area information indicating a physical area of the specific data. The first generation unit is configured to generate a second erase code using the specific data stored in the physical area indicated by the physical area information and the first authentication information. The erase unit is configured to erase data stored in the physical area indicated by the physical area information when the first erase code corresponds to the second erase code.

Storage device, storage control method, computer program product, and storage system

There is provided a data receiving device including a reception controller and a read controller. The reception controller controls an access processing device to write data received through a session established with a communication device on a network to a file on a storage. The read controller manages registration information indicating association between the file and the session, and upon receiving a data reception request specifying a session from an application, outputs a read request for data of the file associated with a specified session to the storage and receive the data read from the storage.

Data receiving device, data receiving method, and non-transitory computer readable medium

According to one embodiment, a storage device includes a storage configured to store data and a controller configured to control the storage. When receiving an instruction to read data from the storage is received, the controller determines whether or not a failure is in the storage device which is a target of the data read. When a failure is acknowledged, the controller refers to a different storage device storing the data including the same data as the data, acquires the same data from the different storage device, and outputs the acquired data to a source of the instruction.

Storage device

A setting storage unit stores first setting information that defines an operation of a first application that runs on a guest OS and second setting information that defines an operation of a second application that runs on at least one of another guest OS and a host OS. A correspondence storage unit stores first identification information for identifying the first setting information and second identification information for identifying the second setting information, in association with each other. An alternative access gaining unit reads from the correspondence storage unit the second identification information corresponding to the first identification information of the first setting information for which an access request is received, and accesses the second setting information of the second identification information that is read out, in place of the first setting information for which the access request is received.

Accessing corresponding alternative operation configuration information of applications running on virtual machines based on requested configuration information indicating data format conversion and user name

According to an embodiment, a communication management apparatus mediates data between an information processing terminal having a temporary memory and an external memory device that is installed outside the information processing terminal. The apparatus includes a receiving unit configured to receive a write request issued by a device other than the information processing terminal for writing the data in the external memory device; a reading-writing unit configured to control reading of the data from the external memory device and control writing of the data in the external memory device; and a delete command issuing unit configured to, when the write request with respect to the external memory device is received, issue a delete command to the information processing terminal for deleting temporary data that is stored in the temporary memory.
