摘要： In an information processing system comprising a storage equipment which includes a logical unit logically assigned to physical devices and an information processing apparatus which sends data input/output requests to the storage equipment, wherein the data input/output requests are transferred through logical paths serving as communication paths to the logical unit, the information processing apparatus comprises a path selection management section which manages configurations of a plurality of blocks into which the logical unit is divided, an I/O request allocation section which allocates data input/output requests to be transmitted to the storage equipment to the logical paths, and I/O processing units which transmit the data input/output requests through the logical paths, according to the allocation determined by the I/O request allocation section, pursuant to an established protocol, wherein the path selection management section assigns at least one logical path to one block.
