摘要

近年来，基于虚拟机的系统对SSD缓存进行了广泛的研究。在本文中，我们提出了一种新的基于虚拟机管理程序的SSD缓存方案，采用一种新的度量来准确地确定每个虚拟机对SSD缓存空间的需求。计算机仿真结果表明，与现有方案相比，该方案大大提高了缓存空间分配的准确性。它还允许与现有方案相比的命中率，而虚拟机的SSD缓存数量较少。

Enhanced Hypervisor-based SSD Cache with Dynamic Cache Scanning and Allocation for Virtualized Cloud System

Recently, SSD caching is widely studied for VM-based systems. In this paper we propose a novel hypervisor-based SSD caching scheme, employing a new metric to accurately determine the demand on SSD cache space of each VM. Computer simulation confirms that it substantially improves the accuracy of cache space allocation compared to the existing schemes. It also allows comparable hit ratio as the existing schemes with less amount of SSD cache for the VMs.
