大规模虚拟集群中可扩展的组管理

Scalable Group Management in Large-Scale Virtualized Clusters

Wei Zhou, Lei Wang, Dan Meng, Lin Yuan, Jianfeng Zhan

摘要:

为了节省成本,近年来越来越多的用户选择在集群系统中,特别是在数据中心中提供虚拟机资源。维护一致的成员视图是可靠的集群管理的基础,它也提出了一些挑战性的问题,部署虚拟机的大规模集群系统(我们称之为虚拟化集群)。本文介绍了我们在大规模虚拟集群中设计和实现可伸缩成员视图管理的经验。本文的主要研究工作包括三个方面:1)提出了一种可扩展的、可靠的管理体系结构,该体系结构采用对等结构和层次结构相结合的方式来维护虚拟集群中成员视图的一致性; 2)提出了一种轻量级的组成员关系算法,该算法能够在单轮消息交换中实现成员视图的一致性; 3)设计并实现了一个可扩展的成员服务,该服务可以提供虚拟机,并在虚拟集群中维护一致的成员视图。本文的工作在2008年11月世界超级计算机500强排名第10位的曙光5000 A上得到了验证。

英文摘要:

To save cost, recently more and more users choose to provision virtual machine resources in cluster systems, especially in data centres. Maintaining a consistent member view is the foundation of reliable cluster managements, and it also raises several challenge issues for large scale cluster systems deployed with virtual machines (which we call virtualized clusters). In this paper, we introduce our experiences in design and implementation of scalable member view management on large-scale virtual clusters. Our research contributions are three-fold: 1) we propose a scalable and reliable management infrastructure that combines a peer-to-peer structure and a hierarchy structure to maintain a consistent member view in virtual clusters; 2) we present a light-weighted group membership algorithm that can reach the consistent member view within a single round of message exchange; and 3) we design and implement a scalable membership service that can provision virtual machines and maintain a consistent member view in virtual clusters. Our work is verified on Dawning 5000A, which ranked No.10 of Top 500 super computers in November, 2008.
