Research on massive data storage in virtual roaming system based on RAID5

摘要

A massive data management method was proposed based on RAID5 against limitations of data expansion, and a lack of automatic data recovery capability in current virtual roaming system: the panoramic data is separated from the roaming system as an independent panoramic data service system (PDSS), and distributed to multiple nodes to performance parallel service taking advantage of disk parallelism of RAID5. In this way, we can enhance the data storage capacity and fault tolerance of the server in a large extend. Finally, a prototype virtual roaming system was designed based on PDSS. The results showed that this method had a good application prospect.
