INPUT/OUTPUT CONTROL DEVICE, INPUT/OUTPUT CONTROL SYSTEM, AND INPUT/OUTPUT CONTROL METHOD

摘要

An input/output control device is connected to an input/output switch which transfers a received input/output instruction to an input/output device whose local address is specified in the input/output instruction. The input/output control device includes a memory and circuitry. The memory stores specific information about a processor and a conversion table for converting a logical address of the input/output device into the local address, with the specific information and the conversion table each being associated with a device group that includes the processor and the input/output device. The circuitry identifies the device group based on the specific information about the processor of sender which information is obtained. The circuitry converts the logical address included in the input/output instruction into the local address which is obtained from the conversion table for the identified device group, and then sends the input/output instruction to the input/output switch.

1. An input/output control device connected to an input/output switch which transfers a received input/output instruction to an input/output device whose local address is specified in the input/output instruction, the input/output control device comprising:
a memory that stores specific information about a processor as well as storing a conversion table for converting a logical address of the input/output device into the local address, with the specific information and the conversion table each being associated with a device group which includes the processor and the input/output device; and circuitry which has a configuration to identify the device group from the specific information about the processor of sender which information is obtained when an input/output instruction is received, convert the logical address included in the input/output instruction into the local address which is obtained from the conversion table for the identified device group, and send the input/output instruction to the input/output switch.
