  • By analyzing and studying four main checkout technologies of redundant array of independent disks (RAID), 6D+2P checkout technology is proposed based on P+Q checkout technology. 6D+2P checkout technology can effectively deal with data recovery when two disks are wrong. The main principle is that it distracts the application data and checkout data into eight disks from one RAID group, thus can ensure the read-write performance and the data security. Experimental results verified that the use ratio and read-write capability of disk array based on 6D+2P are improved effectively, where the use ratio can up to 85%.

Abstract: By analyzing and studying four main checkout technologies of redundant array of independent disks (RAID), 6D+2P checkout technology is proposed based on P+Q checkout technology. 6D+2P checkout technology can effectively deal with data recovery when two disks are wrong. The main principle is that it distracts the application data and checkout data into eight disks from one RAID group, thus can ensure the read-write performance and the data security. Experimental results verified that the use ratio and read-write capability of disk array based on 6D+2P are improved effectively, where the use ratio can up to 85%.
