Abstract

A method, computer program product, and computer system for receiving, by a computing device, a Write-Same operation from a host for a range of logical block addresses of a destination. Data may be recorded in a buffer to indicate that the Write-Same operation is complete prior to completing the Write-Same operation. An acknowledgment may be sent to the host that the Write-Same operation is complete prior to flushing to a final destination. The Write-Same operation for the logical block addresses of the destination may be performed after sending the acknowledgment to the host that the Write-Same operation is complete.
