分布式I/O日志收集系统的设计与实现

Design and implementation of I/O trace collection system in distributed environment

随着存储系统的快速发展,以及实际应用中对存储系统的要求日益苛刻,为了研究存储系统I/O子系统的运行形态,设计并实现了一种分布式I/O日志收集系统,该系统能够通过总控制台同时控制分布式系统的多个节点并行收集分布式系统的I/O日志,为分析和回放分布式系统的I/O日志提供有效的数据,且详细描述了系统的设计与实现。

With the rapid development of information technology applicationI,/O system is becoming more and more compli-cated,especially in the distributed computing environment.In order to explore the I/O behavior in the distributed computing environmentt,his paper designs and implements a novel tracing tool called distributed I/O trace system,which can simultane-ously control each node’s I/O trace collecting behavior in a parallel distributed system.Distributed I/O trace system can also receive the I/O traces collected from each nodet,hen save and manage the I/O traces.This paper describes the design consid-erations and the implementation details.
