摘　　要：为提高集群系统的可靠性和计算性能并降低成本,提出将单一系统映像的集群系统(Single System Image)和分布式复制块设备技术(DRBD)结合起来构建一种高可用集群(SSI-DRBD集群)。这种利用单一系统映像和DRBD技术所构建的集群具有高性能、高可靠、实时性强、易管理和低成本等特点,可作为周期性、高强度和多元信息处理的平台。With the scale of high performance parallel computing systems becoming larger,the fault probability of hardware in these systems is increased.As a result,issues of fault tolerance and reliability are becoming limiting factors on system scalability.This paper approaches a new method for designing a high-available cluster system with OpenSSI and DRBD.The cluster system effectively hides the architecture of cluster,conveniences to use and management,and improves its performance,reliability and availability.
