1. A computer-implemented method, comprising:
issuing, by a first processor, to a supplemental device, an asynchronous request to perform a write operation of data to a first local persistence memory;
copying, by the first processor to a second local persistence memory, the data;
obtaining, by a second processor, a status completion result indicating that the write operation completed; and
in response to obtaining the status completion result, obtaining, by the second processor, a status check result indicating that the write operation successfully wrote the data to the first local persistence memory.
