METHOD AND SYSTEM FOR FACILITATING WRITE LATENCY REDUCTION IN A QUEUE DEPTH OF ONE SCENARIO

Abstract:

One embodiment provides a system which facilitates data management. During operation, the system processes, by a storage device, a write request and data associated with the write request, wherein the storage device comprises a plurality of channels over which to access a non-volatile memory of the storage device. The system writes the data to a first data buffer of the storage device while bypassing a first interface and a memory controller. The system sends the write request to the memory controller via the first interface. The system writes, via a first channel allocated for host write operations, the data from the first data buffer to the non-volatile memory. The system performs a garbage collection operation on the data, which comprises accessing the data via a second channel allocated for garbage collection operations.
