Swift云存储环境下基于I/O的负载均衡算法
Load balancing algorithm based on I/O under Swift cloud storage environment
摘要
Abstract
The cloud storage service of open source cloud computing platform Openstack uses common hardware to build clusters of servers to provide redundancy, highly reliable, scalable data storage for the PB-level data. For the case that part nodes’visit overheating of the cluster and another part’s resource underutilization, this paper improves the consistent hashing algorithm used in the Ring which is the most important component of the core module Swift. Experimental results show that these algorithms give consideration to load balancing to the maximum extent and improve storage resource utili-zation, considering cluster processing capacity of each node, while taking the current load into account and improve the overall performance of the cluster system.关键词
