Abstract: A redundant array of independent nodes are networked together. Each node executes an instance of an application that provides object-based storage. The nodes are grouped into a plurality of systems each having multiple nodes. A data protection level method comprises setting a numerical value of a system dynamic data protection level for each system of nodes; and in response to user input, setting a value of a data protection level for one or more data objects in a system, the value being a fixed numerical value or a dynamic value. If the one or more data objects have a dynamic value of the data protection level in a system, the one or more data objects inherit the system dynamic data protection level of the system in which the one or more data objects reside. The value of the data protection level represents a number of copies of data of the one or more data objects to be kept where the one or more data objects reside.

Abstract translation: 独立节点的冗余阵列联网在一起。 每个节点执行提供基于对象的存储的应用程序的实例。 节点被分组成多个具有多个节点的系统。 数据保护等级方法包括为每个节点系统设置系统动态数据保护级别的数值; 并且响应于用户输入，为系统中的一个或多个数据对象设置数据保护级别的值，该值是固定的数值或动态值。 如果一个或多个数据对象具有系统中的数据保护级别的动态值，则一个或多个数据对象继承其中存在一个或多个数据对象的系统的系统动态数据保护级别。 数据保护级别的值表示要存放在一个或多个数据对象所在的一个或多个数据对象的数据的副本。
