| With the development of virtualization technology, desktop virtualization and server virtualization in the past reliance on computing performance, gradually turned to meet the demand of I/O device performance and safe. The development of a distributed storage system has effectively improve the safety redundancy of the entire storage system and the hyper converged infrastructure, which ensure high availability storage service, it is easy to expand the system architecture and low hardware cost, in actual production more competitive. However, the lack of a distributed storage system itself is too complex, involving two levels of storage hardware and software, and is in the early stages of the rise of open source development, which rapidly change, resulting in the production of its application requires large learning costs. As a universal design underlying storage systems, distributed storage is widely used, so it lacks official tuning method for a specific application guidance, its complex system configuration increases the size and difficulty of research and testing, many corporate IT departments stop research of the difficulties. Faced with the traditional storage distinct mode of operation, especially in the case of traditional storage service objects are large differences desktop virtualization application background is very characteristic test research significance.From the desktop virtualization platform, this paper introduces the basic principles, advantages and disadvantages and domestic and foreign research status from distributed storage to Ceph open-source distributed storage system. Combined with the characteristics of desktop virtualization scenarios, sorting out a feasible distributed storage performance and stability testing program. Special programs for desktop virtualization storage needs, from the local disk, distributed block storage and VM’s disk, these three levels to complete the distributed storage system performance comparison test. Desktop virtualization platform in practical application, the use of virtual machine disk storage provides the ability to support distributed testing, test results are complete finishing 80 desktop virtualization traffic load level select the best distributed storage as its backend Select the stored program summary, and where insufficient research to make improvements. |
