Abstract
A storage network that facilitates the transfer of a data set from a first storage device to a second storage device, without blocking access to the data set during the transfer is provided. An intermediate device for the storage network is provided. The intermediate device comprises a plurality of communication interfaces. Data transfer resources are coupled to the plurality of interfaces, and are used for transferring data access requests identifying the data set from a third interface at least one of a first and second interfaces. A logic engine within the intermediate device is coupled to the interfaces, and is responsive to a control signal to manage the transfer of the data set through the interfaces.
