Each information processing apparatus judges a busy flag of a first port thereof based on a result of comparison of a busy level of the first port and a busy level of a second port of another information processing apparatus. A monitoring apparatus determines from among the information processing apparatuses, a first information processing apparatus and a second information processing apparatus, based on the results of judgment by the information processing apparatuses. An L2 switch changes to the second information processing apparatus, a destination of a frame whose destination is the first information processing apparatus and changes to the first information processing apparatus, a transmission source of the frame whose transmission source is the second information processing apparatus.

Information processing system, monitoring apparatus, and network device

A first storage virtualization device operates in a system in which instructions requested by host computers are assigned to a plurality of storage virtualization devices. The first storage virtualization device includes an interface and a processor. The interface receives a write instruction assigned to the first storage virtualization device, data to be written by the write instruction, and operation statuses of other storage virtualization devices in the system. The processor calculates index values which represent loads when the first storage virtualization device processes the write instruction. The processor selects a second storage virtualization device for the purpose of requesting that it execute the write instruction by use of the operation statuses when the index values are greater than thresholds. The processor transmits the write instruction and the data to the second storage virtualization device.
