摘要: 提出了一种对象放置算法C-SIEVE,它使用离散的数据算法,可以有效地定位数据对象,还解决了对象副本的放置问题.实验表明,该算法能根据存储设备的负载高效且均衡地完成对象映射,对于失效节点的对象恢复也具有很好的性能,是行之有效的.Abstract: A new object placement algorithm C-SIEVE was put forward.It can not only locate data object effectively,but also solves problems of object copies placement by discrete data algorithm.Experiments indicated that this algorithm was effective.It can accomplish efficient and balanced object mapping according to the load of storage devices,but also have a good performance for object recovery once there are invalid storage nodes.
