Abstract: A relay device stores first logical-path information indicating information on communication logical paths used for communication between an information processing apparatus and an input and output device, where the communication logical paths each includes a device logical path used between the relay device and the input and output device. Upon detection of a mismatch between the first logical-path information and second logical-path information that is requested from the information processing apparatus and includes information on target communication logical paths to be used for communication between the information processing apparatus and the input and output device, the relay device controls setting of the device logical path included in each of the communication logical paths so that the communication logical paths are consistent with the target communication logical paths indicated by the second logical-path information.

Abstract: A control method includes: making, by a transmitting apparatus coupled to an information processing apparatus and provided in the transmission and reception system where the transmitting apparatus and a receiving apparatus coupled to an input and output apparatus are coupled with each other through a network, a response to the information processing apparatus in response to a first command received from the information processing apparatus; obtaining, by the transmitting apparatus, a commands from the information processing apparatus after receiving the first command; batch-transferring the commands to the receiving apparatus without making a response to the information processing apparatus; issuing, by the receiving apparatus, the commands transferred from the transmitting apparatus to the input and output apparatus; and notifying, by the receiving apparatus, when the commands is batch-transferred from the transmitting apparatus, the transmitting apparatus about processing completion when processing of all o

Abstract: A host side extension device includes a write data processing unit, a mode setting unit, and a second communication control unit. The write data processing unit executes a compression process on data to be transmitted to an I/O device and generates compressed data. The mode setting unit includes decompression control information to instruct the I/O side extension device not to execute a decompression process on the compressed data and compression control information to instruct the I/O device not to execute a compression process on data in a transmission notice notifying of that an own device is to transmit the compressed data to the I/O device through the I/O side extension device. The second communication control unit transmits the transmission notice including the decompression control information and the compression control information to the I/O device through the I/O side extension device.

Abstract: A relay apparatus performing communication between a first processing apparatus and a second processing apparatus through another relay apparatus, the relay apparatus includes a transmission unit to transmit transmission data to the other relay apparatus, a calculation unit to measure a round trip time (RTT) from transmission of data to the other relay apparatus to receiving of a response, and calculate a transmission time on a basis of the RTT, and a scheduler unit to control transmission times of transmission data to the other relay apparatus outputs, when the scheduler unit detects the transmission data and a size of the detected transmission data is not larger than a specified value, the transmission data to the transmission unit after a time from the detection of the transmission data has passed the transmission time.

Abstract: An extension device that extends a communication path between a host device and an input/output (IO) device, the extension device including a determination unit configured to determine whether a first logical path exists between the host device and the IO device, a logical path establishment unit configured to request the IO device to establish a second logical path between the extension device and the IO device when the first logical path does not exist between the host device and the IO device, and a communication check unit configured to check communication on the second logical path established between the extension device and the IO device that establishes the second logical path.
