The Wisconsin Hierarchically-Redundant, Decoupled storage project (HaRD)investigates the next generation of storage software for hybrid Flash/diskstorage clusters. The main objective of the project is to improve theperformance of storage in a variety of diverse scenarios, including newapplication environments such as photo storage as found in Facebook andFlickr, high-end scientific processing as found in government labs, andlarge-scale data processing such as that found in Google and Microsoft. TheHaRD project focuses on three key issues in order to improve performance ofthese important applications: client-side Flash-based RAID and file-systemintegration, server-side memory reduction and multicore scheduling offile-system tasks, and scheduled network transfers. HaRD pulls together thesetechnologies into a synthesized whole through three targeted storage systems:a scalable photo server, a high-performance checkpoint subsystem, and animproved file system for MapReduce workloads. The impact of this project issignificant, as HaRD helps to shape the storage software architecture of thenext generation of cloud computing services, which are of increasing relevanceto both industry and society at large.

威斯康星州的分层冗余、分离存储项目(HARD)研究了用于混合闪存/磁盘存储群集的新一代存储软件。该项目的主要目标是在各种不同的场景中提高存储的性能，包括新的应用环境，如Facebook和Flickr中的照片存储，政府实验室中的高端科学处理，以及Google和Microsoft中的大规模数据处理。为了提高这些重要应用程序的性能，HARD项目专注于三个关键问题：客户端基于闪存的RAID和文件系统集成、服务器端内存减少和文件系统任务多核调度以及计划的网络传输。Hard通过三个目标存储系统将这些技术整合到一个综合的整体中：可扩展的照片服务器、高性能检查点子系统和针对MapReduce工作负载的改进的文件系统。这个项目的影响是巨大的，因为Hard有助于塑造下一代云计算服务的存储软件架构，这些服务与行业和整个社会的相关性越来越大。
