Abstract:
1. A method of transferring data from a first storage device to a second storage device, comprising: synchronously transferring the data from the first storage device to a first buffer device; asynchronously transferring the data from the first buffer device to a second buffer device; synchronously transferring the data from the second buffer device to the second storage device, wherein the first buffer device acknowledges successful transfer of the data to the first storage device prior to the first buffer device completing transfer of the data to the second buffer device; and providing the data from the first buffer device to the second buffer device using a network, wherein the data is provided from the first storage device in a first format and is provided to the network in a second format that is different from the first format, wherein the first buffer device converts the data from the first format to the second format and sends the data in the second format to the network, and wherein the second buffer device receives the data in the second format from the network and converts the data from the second format into the first format before the data is transferred to the second storage device; wherein the first format is RDF format and the second format is one of TCP/IP or UDP.
