英文摘要	This paper presents vSIP, a new scheme of virtual desktop disk scheduling on sharing storage system for user-interactive performance. The proposed scheme enables requests to be dynamically prioritized based on the interactive feature of applications sending them. To enhance user experience on consolidated desktops, our scheme provides interactive ap-plications with priority requests, which have less latency in accessing storage than requests from non-interactive ap-plications sharing the same storage. To this end, we de-vise a hypervisor extension that classifies interactive ap-plications from non-interactive applications. Our frame-work prioritizes the requests from these applications and limits the requests rate. Our evaluation shows that the proposed scheme significantly improves interactive perfor-mance of storage-sensitive application such as applications launch, Web page loading and video cold playback, when other storage-intensive applications highly disturb the in-teractive applications. In addition, we introduce a guest OS information transfer method, hence the efficiency and accu-racy of the identiffcation of interactive applications can be further improved. ? 2016 Copyright held by the owner/author(s).; EI; 222-231
