SMARC:一种结合SLC和MLC的混合固态盘架构
SMARC: exploit SLC and MLC cells complementarily and effectively within one architecture
摘要
Abstract
This paper presented a novel internally hybrid SSD architecture(SMARC) which consisted of both SLC and MLC flash memory packages,instead of only either SLC or MLC.By periodically migrating data between the two different portions (SLC and MLC space) according to running workloads dynamics,the proposed architecture was able to exploit their respective advantages complementarily to help overall performance,reliability and energy consumption.The simulation results of a variety of workloads shows that SMARC can improve the performance by nearly an order of magnitude.At the same time,it significantly enhances reliability and reduces energy consumption.Furthermore,SMARC can be easily extended to provide differentiated storage services and provide important implications for modem storage systems.关键词
