摘要： A system, method, and machine-readable storage medium for recovering data in a distributed storage system are provided. In some embodiments, the method includes identifying a failing storage device of a first storage node having an inaccessible data segment. When it is determined that the inaccessible data segment cannot be recovered using a first data protection scheme, a first chunk of data associated with the inaccessible data segment is identified and a group associated with the first chunk of data is identified. A second chunk of data associated with the group is selectively retrieved from a second storage node such that data associated with an accessible data segment of the first storage node is not retrieved. The inaccessible data segment is recovered by recovering the first chunk of data using a second data protection scheme and the second chunk of data.

摘要： Methods and systems for managing caching mechanisms in storage systems are provided where a global cache management function manages multiple independent cache pools and a global cache pool. As an example, the method includes: splitting a cache storage into a plurality of independently operating cache pools, each cache pool comprising storage space for storing a plurality of cache blocks for storing data related to an input/output ("I/O") request and metadata associated with each cache pool; receiving the I/O request for writing a data; operating a hash function on the I/O request to assign the I/O request to one of the plurality of cache pools; and writing the data of the I/O request to one or more of the cache blocks associated with the assigned cache pool. In an aspect, this allows efficient I/O processing across multiple processors simultaneously.

摘要： A configuration for a component of a primary node is synchronized with a configuration for a component of a partner node in a different cluster by replicating the primary node configuration with the partner node. A baseline configuration replication comprises a snapshot of a component configuration on the primary. The baseline configuration can be generated by traversing through the configuration objects, capturing their attributes and encapsulating them in a package. The baseline package can then be transferred to the partner node. The configuration objects can be applied on the partner node in the order in which they were captured on the primary node. Attributes of the configuration objects are identified that are to be transformed. Values for the identified attributes are transformed from a name space in the primary node to a name space in the partner node.

摘要： An optimized segment cleaning technique is configured to efficiently clean one or more selected portions or segments of a storage array coupled to one or more nodes of a cluster. A bottom-up approach of the segment cleaning technique is configured to read all blocks of a segment to be cleaned (i.e., an "old" segment) to locate extents stored on the SSDs of the old segment and examine extent metadata to determine whether the extents are valid and, if so, relocate the valid extents to a segment being written (i.e., a "new" segment). A top-down approach of the segment cleaning technique obviates reading of the blocks of the old segment to locate the extents and, instead, examines the extent metadata to determine the valid extents of the old segment. A hybrid approach may extend the top-down approach to include only full stripe read operations needed for relocation and reconstruction of blocks as well as retrieval of valid extents from the stripes, while also avoiding any unnecessary read operations of the bottom-down approach.
摘要翻译：经优化的段清洁技术被配置为有效地清洁耦合到群集的一个或多个节点的存储阵列的一个或多个选定部分或段。分段清洁技术的自下而上的方法被配置为读取待清理的段的所有块（即，“旧”段））来定位存储在旧段的SSD上的区段，并检查扩展元数据以确定是否范围是有效的，如果是，将有效范围重定位到正在写入的段（即“新”段）。段清除技术的自上而下的方法避免了读取旧段的块以定位区段，而是检查元数据的大小以确定旧段的有效范围。混合方法可以扩展自上而下的方法，以仅包括块的重定位和重建所需的全条带读取操作以及从条带检索有效范围，同时还避免了自下而上的方法的任何不必要的读操作。

摘要： 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.
摘要翻译：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。

摘要： A first request to execute a first task is received from a first module in a first address space and by a second module in a second address space. The first task is placed into a task queue for execution in the second address space. Pending responses not yet returned to the first module that are results of execution for other tasks in the second address space are extracted by the second module from a response queue. Requests for the other tasks were previously sent by the first module to the second module for execution in the second address space. The pending responses are compounded. The pending responses and a return value for acknowledgement the first request to execute the first task are combined, by the second module into a combined communication. The combined communication is transmitted by the second module to the first module in the first address space.

摘要： A method, non-transitory computer readable medium, and apparatus that monitors an active virtual storage controller. A determination of when a failure of the active virtual storage controller has occurred is made based on the monitoring. When the failure of the active virtual storage controller is determined to have occurred, storage devices previously assigned to the active virtual storage controller are remapped to a passive virtual storage controller and transactions in a transaction log are replayed. In another example, active storage controllers are monitored with a passive storage controller. When a failure of one of the active storage controllers has occurred based on the monitoring is determined, storage devices previously assigned to the active storage controller are remapped, a transaction log associated with the active storage controller is retrieved from a transaction log database, and transactions in the transaction log are replayed.

摘要： A system and method for connectivity-aware assignment of volumes among the storage controllers of a storage system is provided. In some embodiments, during a discovery phase, a connectivity metric is determined from a device discovery command. The connectivity metric is recorded into a data structure that identifies a plurality of hosts and a plurality of storage controllers of a storage system. In response to the determining of the connectivity metric, a storage controller ownership of a first volume is changed to improve connectivity between a host of the plurality of hosts and the first volume. In some such embodiments, a storage controller ownership of a second volume is changed to balance load among the plurality of storage controllers, and the discovery phase is, in part, a response to the change in the storage controller ownership of the second volume.
