摘要： A management system manages a plurality of logical volumes in a storage system coupled to a host system. The plurality of logical volumes includes a first logical volume provided to the host system and a second logical volume. The management system manages the second logical volume as a duplicate volume of the first logical volume and a first state volume which is a logical volume provided to the host system. The management system changes the second logical volume to a second state volume associated with the first logical volume, which is not a logical volume provided to the host system and which is on standby for a future use by the host system. The management system manages a data difference between data stored in the second logical volume which is the second state volume and data stored in the first logical volume associated with the second logical volume if data is newly stored in the first logical volume.
摘要翻译：管理系统管理耦合到主机系统的存储系统中的多个逻辑卷。多个逻辑卷包括提供给主机系统的第一逻辑卷和第二逻辑卷。管理系统将第二逻辑卷管理为第一逻辑卷的重复卷，以及作为向主机系统提供的逻辑卷的第一状态卷。管理系统将第二逻辑卷更改为与第一逻辑卷相关联的第二状态卷，该第二逻辑卷不是提供给主机系统的逻辑卷，并且被备用以供主机系统将来使用。如果数据被新存储在第一逻辑卷中，则管理系统管理存储在作为第二状态卷的第二逻辑卷中的数据与存储在与第二逻辑卷相关联的第一逻辑卷中的数据之间的数据差异。

摘要： A distributed storage system comprises a plurality of storage nodes which includes multiple resources including multiple kinds of resources. Each of the multiple storage nodes among the plurality of storage nodes is configured to execute an aggregation task which has been assigned to the storage node among aggregation tasks, Each of the aggregation tasks is a task for aggregating statistics relating to a resource among the multiple resources which corresponds to the task, to the storage node to which the task has been assigned.

摘要： A management system is configured to identify one or more requirements with respect to the primary DC, identify one or more suitable resources which are resources suitable to the identified requirements, from among available resources which are resources that can be used in the secondary DC, based on SPECs of the available resources and metrics (e.g. resources usage and resources workload) from the primary DC, and create a DR (Disaster Recovery) plan by mapping configurations with respect to the identified suitable resources to at least one of the identified requirements.
摘要翻译：管理系统被配置为从相对于主DC的一个或多个要求来识别作为可以在次要DC中使用的资源的可用资源中的适合于所识别的需求的资源的一个或多个适当资源关于来自主DC的可用资源和度量（例如资源使用和资源工作负载）的规格，并且通过将关于所识别的合适资源的配置映射到所识别的要求中的至少一个来创建DR（灾难恢复）计划。
