基于Intel ISA-L的RS-RAID系统的研究与实现
Research and implementation on Reed Solomon RAID based on Intel ISA-L
摘要
Abstract
Due to the limitation of traditional RAID technology, traditional RAID can no longer meet the stringent require-ments of storage. RS-RAID(Reed Solomon RAID)can ensure a higher reliability and space utilization. But poor I/O and recovery performance still exist. A RS-RAID, which accelerates the calculation speed by using Intel ISA-L(Intelligent Storage Acceleration Library)and reduces the time of data recovery by using valid data bitmap, which makes RS-RAID recover the valid data only, can solve these problems. With these steps, RAID system becomes more reliable and more efficient.关键词
