摘要

DataMesh是一个研究项目,其目标是开发软件,以最大限度地提高大容量存储I/O的性能,同时提供高可用性、易用性和可扩展性。DataMesh硬件架构是一个磁盘节点阵列,每个磁盘都有一个专用的20-MIPS单芯片处理器和8- 32mb RAM。这些节点通过一个快速、可靠的小区域网络连接起来,并被编程成一个单一的存储服务器。DataMesh项目的第一阶段将提供智能磁盘阵列;第二阶段将扩展到文件系统;阶段3将支持并行数据库、数据搜索和其他特定于应用程序的功能。这项工作的最初目标是用于高性能工作站组的存储服务器,尽管这些技术适用于几个不同的问题。

DataMesh-parallel storage systems for the 1990s
A description is given of DataMesh, a research project with the goal of developing software to maximize the performance of mass storage I/O, while providing high availability, ease of use, and scalability. The DataMesh hardware architecture is that of an array of disk nodes, with each disk having a dedicated 20-MIPS single-chip processor and 8-32 MBytes RAM. The nodes are linked by a fast, reliable, small-area network, and programmed to appear as a single storage server. Phase 1 of the DataMesh project will provide smart disk arrays; phase 2 will expand this to include file systems; and phase 3 will support parallel databases, data searches, and other application-specific functions. The initial target of the work is storage servers for groups of high-powered workstations, although the techniques are applicable to several different problems.<>
