An asymmetric data mirroring method with a local storage device and a remote storage device being separated by large distances is disclosed. A server determines a predetermined time period associated with a round trip latency between the server and a remote storage device. The server submits a request to a local storage device and to the remote storage device. The server submits additional requests to the local and remote storage devices during the predetermined time period. The server determines whether an acknowledgement associated with the request has been received from the remote storage device during the predetermined time period. The server resubmits the request and the additional requests to the remote storage device if the acknowledgement is not received. If an acknowledgement is received, the server continues submission of additional new requests to the local and remote storage devices.
