PROBLEM TO BE SOLVED: To share an I/O card among a plurality of servers while preventing deterioration of performance of I/O access. SOLUTION: An I/O card sharing mechanism 400 for relaying an answer signal from the I/O card 501 to servers #1-#n replaces an identifier of a server of a requesting source embedded in an MMIO base address by an I/O processor blade 600 to an address of header information of the answer signal, whereby an I/O card of a general bus can be shared. After starting the I/O card 501, the I/O processor blade 600 does not intervene in transfer of the answer signal, and hardware of the I/O card sharing mechanism 400 performs the address replacement.
