Research of Input and Output Technology Based on Virtualized Cluster

Abstract

This paper researches and analyses the model of virtualization in the current trend of cloud computing technology and management mechanism of Para virtualization based on Xen according to the characteristics of virtualization. In this mode, we analyses the I/O scheduler's result which impacts for the entire cluster system in the virtual machines and Drawing out Visualize formula, which provides Method and Basis for the I/O Load Balancing of system. At the end, this paper proposes a Real-time dynamic I/O Scheduling policy.
