Abstract: Improved techniques for disaster recover within storage area networks are disclosed. Embodiments include replicating a LIF of a primary cluster on a secondary cluster. LIF configuration information is extracted from the primary cluster. A peer node from a secondary cluster is located. One or more ports are located on the located peer node that match a connectivity of the LIF from the primary cluster. One or more ports are identified based upon one or more filtering criteria to generate a candidate port list. A port from the candidate port list is selected based at least upon a load of the port. Other embodiments are described and claimed.

Abstract: Improved techniques for disaster recovery of storage service accessible through storage area networks are disclosed. Embodiments include establishing peer relationships between nodes of primary and secondary computing clusters. Configuration information is replicated in near synchronous manner from a primary cluster and used to configure a secondary cluster in a similar manner. Host data is replicated in synchronous manner for all the storage devices and LUNs within them. The secondary cluster is kept updated continuously with configuration information and user data in LUNs on storage devices such that a host may be served data from the secondary cluster when the primary cluster experiences a disaster or failure. Other embodiments are described and claimed.

Abstract: Data consistency and availability can be provided at the granularity of logical storage objects in storage solutions that use storage virtualization in clustered storage environments. To ensure consistency of data across different storage elements, synchronization is performed across the different storage elements. Changes to data are synchronized across storage elements in different clusters by propagating the changes from a primary logical storage object to a secondary logical storage object. To satisfy the strictest RPOs while maintaining performance, change requests are intercepted prior to being sent to a filesystem that hosts the primary logical storage object and propagated to a different managing storage element associated with the secondary logical storage object.

Abstract translation: 公开了通过存储区域网络访问的用于存储服务的灾难恢复的改进的技术。 实施例包括在主计算集群和次计算集群的节点之间建立对等关系。 配置信息以几乎同步的方式从主集群复制，并用于以类似的方式配置辅助集群。 主机数据以同步方式复制到其中的所有存储设备和LUN。 辅助群集将不断更新存储设备上的LUN中的配置信息和用户数据，以便在主群集遇到灾难或故障时主机可能会从辅助群集中提供数据。 描述和要求保护其他实施例。

Abstract: Techniques to managing non-disruptive SAN availability in a partitioned cluster comprising one or more components configured to determine whether to separate a cluster into two or more partitions, notify one or more responsive cluster nodes to separate the cluster into a first partition and a second partition, update one or more access states, notify the host that access states of one or more network paths has been updated, and provide the one or more access states. Other embodiments are described and claimed.

Abstract translation: 可以在集群存储环境中使用存储虚拟化的存储解决方案中的逻辑存储对象的粒度提供数据一致性和可用性。 为了确保不同存储元件之间的数据的一致性，跨不同存储元件执行同步。 通过将更改从主逻辑存储对象传播到辅助逻辑存储对象，对数据的更改在不同群集中的存储元素之间进行同步。 为了在维护性能的同时满足最严格的RPO，在发送到托管主逻辑存储对象的文件系统之前，更改请求将被拦截，并传播到与辅助逻辑存储对象关联的其他管理存储元素。
