Dae-Sik Ko · The Journal of Advanced Navigation Technology · 2011
If the System is downed by computer or disasters, it can have a bad influence on the reliability of the corporation and business continuity because all companies are computerized. Accordingly, interest on the business continuity without the loss of data in the corporate is increasing. In this paper, system faults have been defined as physical faults and logical faults and CDP solution using Flash SSD has been proposed for enhancing IOPS which is needed for realtime-backup. In order to measure IOPS performance of the CDP using Flash SSD, we constructed an experimental system. From the results we can see that IOPS performance of CDP using Flash SSD is about 50 times more effective than that of the S-ATA.
