Sustainable Operation Algorithm for High Availability with Integrated Desktop Storage Based on Virtualization

Recently, following the rapid development of IT, diverse virtualization-based studies have been conducted on big data storage. Among the diverse studies, desktop storage virtualization integrates unused storage in distributed legacy desktops using virtualization and provides integrated storage to users for other purposes. In the case of this desktop storage virtualization, high availability is regarded as very important to providing reliability to storage users. In addition, although studies on hierarchical structures and resource incorporation in desktop-based integration environments have been conducted, studies on efficient operations following the occurrence of server faults are insufficient. To achieve this operational high availability, in the present paper, a Sustainable Operation Algorithm (SOA) that can actively respond to the occurrence of desktop server faults in desktop-based storage integration environments is proposed. If the SOA is applied in desktop-based integration environments, desktops can be easily added or removed. The alternative server actively operates following the occurrence of faults. Finally, the SOA provides high QoS to storage users.
