摘要
This disclosure describes techniques for providing early acknowledgments to a source device performing a data write operation within a data center or across a geographically-distributed data center. In one example, this disclosure describes a method that includes receiving, by a gateway device and from a source device within a local data center, data to be stored at a remote destination device that is located within a remote data center; storing, by the gateway device, the data to high-speed memory included within the gateway device; transmitting, by the gateway device, the data over a connection to the remote data center; after transmitting the data and before the data is stored at the remote destination device, outputting, by the gateway device to the source device, a local acknowledgment, wherein the local acknowledgment indicates to the source device that the data can be assumed to have been stored at the remote destination device.
