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

点击翻译按钮获取中文摘要

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.
