METHOD AND SYSTEM FOR FACILITATING DATA PLACEMENT AND CONTROL OF PHYSICAL ADDRESSES WITH MULTI-QUEUE I/O BLOCKS

Abstract:

A system is provided to receive a request to write a sector of data to a non-volatile storage device, wherein the request is associated with a physical address in the non-volatile storage device at which the sector of data is to be written. The system identifies, based on the physical address, a channel buffer to which the sector of data is to be transmitted, and stores the sector of data in the channel buffer. Responsive to determining that the channel buffer stores other sectors, the system writes the sector of data and the other sectors of data to the non-volatile storage device based on the physical address.
