Improving the performance and reliability of solid-state device based storage systems

该研究计划的主要目标是探索固态设备在存储层次结构中的使用。存储技术（特别是固态设备）的最新进展正在为存储系统的性能、能源效率和可靠性带来一系列新的挑战和机遇。固态设备具有与常规磁盘非常不同的性能特征，并且它们表现出截然不同的功耗模式和故障模式。在这项研究中，我们建议将固态设备在现有的存储层次结构中，创建这些设备和常规磁盘的混合配置，并探索如何使用这种组合来提供更好的存储性能和可靠性保证。我们正在为这项研究申请混合驱动器存储服务器的资金。

The primary goal of this research program is to explore the use of solid-state devices in storage hierarchies. Recent advances in storage technologies, particularly solid-state devices, are creating a new set of challenges and opportunities related to performance, energy efficiency and reliability for storage systems. Solid state devices have very different performance characteristics from regular disks and they exhibit vastly different power consumption patterns and failure modes. In this research, we propose to incorporate solid-state devices in existing storage hierarchies, create hybrid configurations of these devices and regular disks, and explore how this combination can be used to provide better storage performance and reliability guarantees. We are requesting funds for a hybrid-drive storage server for this research.
