High Performance Solid State Storage Under Linux

Free registration required

Executive Summary

Solid State Drives (SSDs) allow single-drive performance that is far greater than disks can produce. Their low latency and potential for parallel operations mean that they are able to read and write data at speeds that strain operating system I/O interfaces. Additionally, their performance characteristics expose gaps in existing benchmarking methodologies. The paper discusses the impact on Linux system design of a prototype PCI Express SSD that operates at least an order of magnitude faster than most drives available today. The paper develops benchmarking strategies and focuses on several areas where current Linux systems need improvement, and suggest methods of taking full advantage of such high-performance solid state storage.
