| Abstract: | HSMDR (high speed and mass data recording) is the most challenging topic in the area of data storage and is great important in both scientific research and practice. The software RAID (redundant array of inexpensive disks) is one of the most popular HSMDR systems. This study focuses on the design of software RAID after careful analysis of SCSI (small computer system interface) technology and storage device recording processes. A data recording model based on software RAID is established and verified by a software optical RAID. This model is of universal guidance to the design of software RAID. |
