<p>An object of the present invention is to efficiently perform load balancing between Fibre Channel switches and storage apparatuses, avoiding communication congestion, and maintaining high system performance. An aspect of the present invention provides a method for controlling a communication bandwidth between a network switch (21) having a plurality of ports for forming a network, and a storage apparatus (4) having ports respectively connected to at least two of the ports, the method including: transferring one or more data frames to the storage apparatus via a first port of the network switch connected to the storage apparatus; determining whether or not an overflow has occurred in a first buffer memory associated with the first port during the transfer of the one or more data frames; identifying, if an overflow has occurred in the first buffer memory, a second port of the network switch connected to the storage apparatus; and transferring the one or more data frames to the storage apparatus via the first port and the second port.</p> |
