Abstract: Methods and systems for sharing access to a computer resource accessible by a bus between two controllers are provided. For example, a machine implemented method of sharing access to computer resources includes requesting access to a bus from a processor of a first controller to access a device shared with a processor of a second controller; waiting for a positive response from the second controller; when the positive response is received, accessing the bus for less than a first timeout period; resetting a timer before the timer reaches the first timeout period to extend access to the bus, when access is not complete and a total access time is less than a second timeout period; and releasing the bus when access is complete or the second timeout period has been reached.

Abstract: A system and method for avoiding object identifier collisions in a cluster environment is provided. Upon creation of the cluster, volume location databases negotiate ranges for data set identifiers (DSIDs) between a first site and a second site of the cluster. Any pre-existing objects are remapped into an object identifier range associated with the particular site hosting the object.

Abstract: A low-overhead merge technique enables restart of a merge operation with minimal logging of state information relating to progress of the merge operation by a volume layer of a storage input/output (I/O) stack executing on one or more nodes of a cluster. The technique enables restart of the merge operation by ensuring that metadata, i.e., metadata pages, generated during the merge operation is not subject to de-duplication by providing a unique value in each metadata page that distinguishes the page, i.e., renders the page distinct or "unique", from other metadata pages in an extent store. In addition, the technique ensures that a reference count on each metadata page is a value denoting a lack of de-duplication. To that end, the extent store layer is configured to not increment the reference count for a metadata page if, during the merge operation, the page is identical (and thus subject to deduplication) to an existing metadata page in the extent store.

Abstract translation: 低开销合并技术使得能够通过在集群的一个或多个节点上执行的存储输入/输出（I / O）堆栈的卷层的最小记录关于合并操作的进展的状态信息的记录来重新启动合并操作。 。 该技术通过确保在合并操作期间生成的元数据页面不受重复数据删除的影响，从而通过在每个元数据页面中提供唯一的值来区分页面，即，使页面不同 或“唯一”，从范围存储中的其他元数据页面。 此外，该技术确保每个元数据页面上的引用计数是表示缺少重复数据删除的值。 为此，如果在合并操作期间页面与扩展存储区中的现有元数据页面相同（并因此进行重复数据删除），则扩展区存储层被配置为不递增元数据页面的引用计数。

Abstract: One or more techniques and/or systems are provided for coalescing storage operations. For example, a storage operation may be received from a client by a file server configured to provide access to data stored within one or more storage devices. A notification of the storage operation may be created for tracking purposes. A coalescing policy may be enforced such that additional notifications are not created for subsequent storage operations until the coalescing policy is unenforced (e.g., after a predefined period of time lapses). Enforcement of the coalescing policy, for example, mitigates tracking an excess number of storage operations that may otherwise utilize processing resources, consume bandwidth, provide redundant information that may be of little to no value, etc.

Abstract: Technology is disclosed for backing up data to and recovering data from a destination storage system that stores data in a format different form that of a primary storage system ("the technology"). A replication stream having the data of multiple files, metadata of the files, and reference maps including a mapping of the corresponding file to a portion of the data of the corresponding file is generated at the primary storage system. The replication stream is sent to a parser to map or convert the data, the files, and the reference maps to multiple storage objects in a format the destination storage system is configured to store. Various types of storage objects are generated, including a first type of the storage objects having the data, a second type of storage objects storing the reference maps, and a third type of the storage objects storing metadata of the files.

Abstract: Non-volatile random access memory (NVRAM) caching and logging may be configured to deliver low latency acknowledgements of input/output (I/O) requests, such as write requests, while avoiding loss of data associated with the requests that may occur as a result of power failures. Write data associated with one or more write requests may be received at a node of a cluster. The write data may be stored in a portion of an NVRAM configured as, e.g., a persistent write-back cache of the node, while parameters of the request may be stored in another portion of the NVRAM configured as one or more logs, e.g., NVLogs. The write data may be organized into separate variable length blocks or extents and "written back" out-of-order from the write back cache to storage devices, such as solid state drives (SSDs). The write data may be preserved in the write-back cache until each extent is safely and successfully stored on SSD (i.e., in the event of power loss), or operations associated with the write request are sufficiently logged on NVLog, to thereby provide efficient recovery when attempting to restore the write data preserved in the cache to the SSDs.

Abstract: Technology is disclosed for improving the storage efficiency and communication efficiency for a storage client device by maximizing the cache hit rate and minimizing data requests to the storage server. The storage server provides a duplication list to the storage client device. The duplication list contains references (e.g. storage addresses) to data blocks that contain duplicate data content. The storage client uses the duplication list to improve the cache hit rate. The duplication list is pruned to contain references to data blocks relevant to the storage client device. The storage server can prune the duplication list based on a working set of storage objects for a client. Alternatively, the storage server can prune the duplication list based on content characteristics, e.g. duplication degree and access frequency. Duplicate blocks to which the client does not have access can be excluded from the duplication list.
