Optimizing RAID/SSD controllers with lifetime extension for flash-based SSD array
Lei Han, Zhaoyan Shen, Zili Shao, Tao Li · 2018
Flash-based SSD RAID arrays are increasingly being deployed in data centers. Compared with HDD arrays, SSD arrays drastically enhance storage density and I/O performance, and reduce power and rack space. Nevertheless, SSDs suffer aging issues. Though prior studies have been conducted to address this disadvantage, effective techniques of RAID/SSD controllers are urgently needed to extend the lifetime of SSD arrays.
