摘要： A data transfer method for transferring data frames according to Fibre Channel Protocol between a first storage control unit and a second storage control unit in a remote copy system, wherein the remote copy system includes a first storage control unit, and a second storage control unit connected via a communication tool to the first storage control unit, that receives data from the first storage control unit. A buffer-to-buffer credit value applied to the data frame transfer is increased according to the distance between the first storage control unit and the second storage control unit.

摘要： This invention provides data transfer control with no throughput reduction or possibility thereof in data transfer between a sender port and a receiver port, separated by a great distance, for example, in the case where the sender port and the receiver port, between which data is transferred according to Fibre Channel Protocol, constitute a remote copy system between a plurality of storage control units. A data transfer method for transferring data frames according to Fibre Channel Protocol between a first storage control unit and a second storage control unit in a remote copy system, wherein the remote copy system includes a first storage control unit, and a second storage control unit connected via a communication tool to the first storage control unit, that receives data from the first storage control unit. A buffer-to-buffer credit value applied to the data frame transfer is increased according to the distance between the first storage control unit and the second storage control unit.
