Abstract

In this paper, we point out that SSDs may give a new opportunity in performance enhancement of virtualization environment. By the analysis of virtio, a de-facto standard framework for virtual I/O devices and the evaluation experiments of original version of virtio, we show that in order to get better scalability for SSDs, virtio needs to be redesign on the new assumption that requests of different types from different VMs are quite independent. Under such an assumption, a new framework is designed based on virtio, which is sirtio, as we put scalability the first place. According to our evaluation, sirtio can improve the scalability of SSDs in virtualization environment.
