基于Ceph对象存储集群的负载均衡设计与实现

摘要

海量并行数据访问ceph对象存储集群时,会出现访问数据错误率增加和访问速率降低的问题.首先设计和部署ceph对象存储集群,根据用户请求数设计对象网关节点,实现用户数据的交互功能,然后在服务节点安装和部署haproxy,实现服务节点的负载均衡功能,能够降低服务节点的压力,最后设计和实现四种基于ceph对象网关节点的存储集群.通过大量对比测试,本设计方案的数据访问错误率降低0.96%,用户数据的访问速率提升74.04%.%When mass parallel data access the ceph object storage cluster, the problems of increasing error rate and low access rate are existed. At the first, the authors design and deploy the ceph object storage cluster, and then design object gateway nodes to achieve interactive features of user data according to user requests. Second, I install and deploy haproxy on four service nodes, which can achieve the function of load balancing and reduce the pressure of four service nodes. Finally, the authors design and implementation of four different kinds of storage clusters based on ceph object gateway nodes. Through a lot of comparison tests, this design can not only reduce the error rate of 0.96 percent, but also enhance access rate of 74.04 percent.
