文章在对象存储设备管理的基础上,对存储对象的属性进行了扩展,增加了可靠性指标。然后利用逻辑设备的可用性属性,在不同的设备上存储数据的副本,计算用户数据可靠性并自动与用户要求进行比较和调节。
In this paper, we expand the dependability attribute of storage device based on object storage, then use dependability of logical device, distribute multiple data sets in different device. By this method, dependability of data can be computed and compared with user's requests automatically.
