摘要： According to an embodiment, a transfer device includes one or more hardware processors configured to function as a control unit and a first transfer unit. The control unit is configured to, by referring to scheduling information indicating a schedule of a timing at which data transfer occurs, dynamically control a maximum data request size that transfer of the data from a first storage unit to a second storage unit can be requested without waiting for reception of read completion notification. The first transfer unit is configured to read the data from the first storage unit and transfer the data to the second storage unit in units of maximum data transfer size equal to or less than the maximum data request size.

摘要： According to one embodiment, a communication apparatus communicates with a partner apparatus through a network. The communication apparatus comprises a protocol analyzing unit that analyzes a transmission frame or a reception frame, the transmission frame being generated by an external CPU and being transmitted to the partner apparatus, the reception frame being received from the partner apparatus. The communication apparatus comprises a connection information managing unit that allocates a storage area in which connection information is stored, in a predetermined storing apparatus that can be accessed by the CPU, when a connection establishment request is detected from the transmission frame or the reception frame as a result of the analysis by the protocol analyzing unit, the connection information being used while being shared with the CPU. The protocol analyzing unit notifies the CPU of information indicating the storage area allocated by the connection information managing unit.

摘要： According to an embodiment, an access control apparatus includes a determiner and a controller. The determiner is configured to determine whether an access state of a first device to a storage device satisfies an exclusion criterion for access to the storage device from a second device. The controller is configured to prohibit the access to the storage device from the second device when the access state of the first device satisfies the exclusion criterion.

摘要： According to an embodiment, a communication apparatus includes a plurality of virtual machines, a storage unit, a transfer unit, and a descriptor output unit. The storage unit includes a multicast storage area specified for each multicast group and storing a multicast frame addressed to virtual machines belonging to a multicast group. The transfer unit writes the multicast frame into a multicast transfer virtual storage area mapped to the multicast storage area. The descriptor output unit outputs a descriptor of the multicast frame to the virtual machines belonging to the multicast group. The virtual machine includes a descriptor receiving unit and a reading unit. The descriptor receiving unit receives the descriptor. When the descriptor is received by the descriptor receiving unit, the reading unit reads the multicast frame from the multicast storage area specified based on the descriptor.
