Abstract: One or more techniques and/or systems are provided for migrating a trust relationship. For example, a first storage cluster and a second storage cluster have a disaster recovery relationship where the second storage cluster provides failover client access to replicated data, replicated from the first storage cluster to the second storage cluster, in the event the first storage cluster fails. The first storage cluster may have a trust relationship with a third storage cluster, such that data is mirrored from a volume of the first storage cluster into a mirrored volume of the third storage cluster based upon the trust relationship. In the event the first storage cluster fails over to the second storage cluster due to a disaster at the first storage cluster, the trust relationship is migrated to be between the second storage cluster and the third storage cluster for non-disruptive mirroring of data to the mirrored volume.

Abstract: Techniques for load balancing and fault tolerant service are described. An apparatus may comprise load balancing and fault tolerant component operative to execute a load balancing and fault tolerant service in a distributed data system. The load balancing and fault tolerant service distributes a load of a task to a first node in a cluster of nodes using a routing table. The load balancing and fault tolerant service stores information to indicate the first node from the cluster of nodes is assigned to perform the task. The load balancing and fault tolerant service detects a failure condition for the first node. The load balancing and fault tolerant service moves the task to a second node from the cluster of nodes to perform the task for the first node upon occurrence of the failure condition.

Abstract translation: 描述负载平衡和容错服务的技术。 装置可以包括负载平衡和容错组件，其可操作以在分布式数据系统中执行负载平衡和容错服务。 负载平衡和容错服务使用路由表将任务负载分配到节点集群中的第一个节点。 负载平衡和容错服务存储指示来自节点簇的第一个节点的信息，用于执行任务。 负载均衡和容错服务检测第一个节点的故障状态。 负载平衡和容错服务将任务从节点集群移动到第二个节点，以便在发生故障条件时执行第一个节点的任务。
