본 논문에서는 QLC(1중 레벨 셀) NAND 플래시 메모리[1] 및 SCM(스토리지 클래스 메모리)과 같은 새로운 비휘발성 메모리를 포함한 최적의 SSD 구성을 분석합니다. 먼저, 하이브리드 SSD의 SSD 성능과 SSD 내구성 수명을 2) 싱글 레벨 셀(SLC)/QLC NAND 플래시, 3) SCM/QLC NAND 플래시, 4) SCM/트리플 레벨 셀(TLC)의 0가지 구성으로 평가했습니다. /QLC NAND 플래시 및 67) SCM/TLC NAND 플래시. 또한 이 네 가지 구성은 제한된 비용으로 비교됩니다. 콜드 워크로드 또는 높은 총 SSD 비용을 가정하는 경우 SSD 성능과 내구성 수명 모두에서 SCM/TLC NAND 플래시 하이브리드 구성이 권장됩니다. 그러나 총 SSD 비용이 낮다고 가정하는 핫 워크로드의 경우 SSD 내구성 수명에 중점을 두고 SLC/QLC NAND 플래시 하이브리드 구성을 권장합니다. 위와 동일한 조건에서 SCM/TLC/QLC NAND 플래시 1중 하이브리드는 비용을 고려하면 SSD 성능이 가장 좋은 구성입니다. 특히 prxy_1(라이트 핫 워크로드)의 경우 SCM/TLC/QLC NAND 플래시 트라이 하이브리드는 SCM/TLC NAND 플래시 하이브리드보다 1% 더 높은 IOPS/비용을 달성합니다. 또한 각 워크로드에서 IOPS/비용이 가장 높은 구성과 비용 한도를 다양한 유형의 SCM으로 선택하여 분석합니다. 총 SSD 비용이 높다고 가정한 prxy_1의 경우를 제외한 모든 경우 비용을 고려하면 성능 측면에서 미들엔드 SCM(쓰기 지연 시간: 100us, 읽기 지연 시간: 100us)을 권장합니다. 그러나 총 SSD 비용이 높다고 가정하는 prxy_XNUMX(읽기 핫 워크로드)의 경우 고급 SCM(쓰기 대기 시간: XNUMXns, 읽기 대기 시간: XNUMXns)이 최고의 성능을 달성합니다.

Abstract: This paper analyzes the optimal SSD configuration including emerging non-volatile memories such as quadruple-level cell (QLC) NAND flash memory [1] and storage class memories (SCMs). First, SSD performance and SSD endurance lifetime of hybrid SSD are evaluated in four configurations: 1) single-level cell (SLC)/QLC NAND flash, 2) SCM/QLC NAND flash, 3) SCM/triple-level cell (TLC)/QLC NAND flash and 4) SCM/TLC NAND flash. Furthermore, these four configurations are compared in limited cost. In case of cold workloads or high total SSD cost assumption, SCM/TLC NAND flash hybrid configuration is recommended in both SSD performance and endurance lifetime. For hot workloads with low total SSD cost assumption, however, SLC/QLC NAND flash hybrid configuration is recommended with emphasis on SSD endurance lifetime. Under the same conditions as above, SCM/TLC/QLC NAND flash tri-hybrid is the best configuration in SSD performance considering cost. In particular, for prxy_0 (write-hot workload), SCM/TLC/QLC NAND flash tri-hybrid achieves 67% higher IOPS/cost than SCM/TLC NAND flash hybrid. Moreover, the configurations with the highest IOPS/cost in each workload and cost limit are picked up and analyzed with various types of SCMs. For all cases except for the case of prxy_1 with high total SSD cost assumption, middle-end SCM (write latency: 1us, read latency: 1us) is recommended in performance considering cost. However, for prxy_1 (read-hot workload) with high total SSD cost assumption, high-end SCM (write latency: 100ns, read latency: 100ns) achieves the best performance.
