Este artigo analisa a configuração SSD ideal, incluindo memórias não voláteis emergentes, como memória flash NAND de célula de nível quádruplo (QLC) [1] e memórias de classe de armazenamento (SCMs). Primeiro, o desempenho do SSD e a vida útil do SSD híbrido são avaliados em quatro configurações: 1) célula de nível único (SLC)/flash NAND QLC, 2) flash NAND SCM/QLC, 3) célula SCM/nível triplo (TLC). /QLC NAND flash e 4) SCM/TLC NAND flash. Além disso, estas quatro configurações são comparadas em termos de custo limitado. No caso de cargas de trabalho frias ou suposição de alto custo total de SSD, a configuração híbrida flash NAND SCM/TLC é recomendada tanto no desempenho do SSD quanto na vida útil da resistência. No entanto, para cargas de trabalho intensas com baixo pressuposto de custo total de SSD, a configuração híbrida flash NAND SLC/QLC é recomendada com ênfase na vida útil do SSD. Nas mesmas condições acima, o flash tri-híbrido SCM/TLC/QLC NAND é a melhor configuração em desempenho de SSD considerando o custo. Em particular, para prxy_0 (carga de trabalho de gravação intensa), o flash tri-híbrido SCM/TLC/QLC NAND atinge IOPS/custo 67% maior do que o híbrido flash SCM/TLC NAND. Além disso, as configurações com maior IOPS/custo em cada carga de trabalho e limite de custo são selecionadas e analisadas com diversos tipos de SCMs. Para todos os casos, exceto o caso de prxy_1 com suposição de alto custo total de SSD, o SCM intermediário (latência de gravação: 1us, latência de leitura: 1us) é recomendado no desempenho, considerando o custo. No entanto, para prxy_1 (carga de trabalho de leitura intensa) com suposição de alto custo total de SSD, o SCM de ponta (latência de gravação: 100ns, latência de leitura: 100ns) atinge o melhor desempenho.

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.
