- Abstract
The advent of big data age has brought about a growing scale of the storage system, as well as huge power consumption, so energy-saving storage system is important progress towards sustainable development. Based on sequential data storage featured workload, we, by adding a solid state disk(SSD) and a parity disk on S-RAID, haveoptimized random reads and writes by means of Reed-Solomon(RS) code, extended the standby time of the disks, effectively avoided the frequent disk startup, and finally achieved the goal of energy saving. The experiments show that, the performance of the MPS-RAID, which consists of 12 disks and an SSD, has improved to some degree, and the energy consumption has reduced by over 20%in EXT4, NTFS, NILFS file systems.
