Early acknowledgment for write operations

A method comprising:

• receiving, by a gateway device and from a source device within a data center, data to be stored at a remote destination device not located within the data center;
• generating a plurality of data segments that enable the data to be reconstructed from a subset of the plurality of the data segments;
• transmitting, by the gateway device, each of the plurality of data segments by outputting the plurality of data segments over one or more links of a network to a different one of a plurality of remote data centers;
• and
• based at least on outputting each of the plurality of data segments over the one or more links of the network to complete transmission of the data to the remote destination device and before the data is stored at the remote destination device, outputting, by the gateway device and 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, and wherein outputting the local acknowledgement after transmitting each of the data segments enables the data to be stored at the remote destination device even if the data center fails.

A storage device for storing computer-readable instructions that, when executed, configure processing circuitry to:

• receive, from a source device within a data center, data to be stored at a remote destination device not located within the data center;
• generate a plurality of data segments that enable the data to be reconstructed from a subset of the plurality of the data segments;
• transmit each of the plurality of data segments by outputting the plurality of data segments over one or more links of a network to a different one of a plurality of remote data centers;
• and
• based at least on outputting each of the plurality of data segments over the one or more links of the network to complete transmission of the data to the remote destination device and before the data is stored at the remote destination device, output, 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, and wherein outputting the local acknowledgement after transmitting each of the data segments enables the data to be stored at the remote destination device even if the data center fails.
