An insightful write buffer scheme for improving SSD performance in home cloud server

摘要

Nowadays, home cloud server uses SSD as its main storage due to the positive characteristics of the SSD such as high performance and low energy consumption. But, the frequent fsync calls generated by software platforms of the home cloud server negatively affect I/O performance and lifespan of the SSD, because it generates massive random-write traffic. This paper introduces a smart SSD model which efficiently reflects write requests to the storage, with process-aware flush operation. Experimental results show that our SSD model reduces response time and the number of writes by up to 12.6% and 17.9%, respectively, compared with conventional SSD.
