Abstract: A system can apply file placement rules to dynamically place files and directories within file system views backed by objects in an object storage system. After detection of an update to a first file system view that causes an update of an object in a storage grid, an object manager begins evaluation of file placement rules against metadata of the object. For each file placement rule that is triggered, the object manager determines identifies gateways that export the first file system view. The object manager then instructs the gateways to update their representations of the first file system view. The disclosed embodiments may be able to scale to managing hundreds of billions of files spanning thousands of file system views, especially in the presence of disconnected operation.

Abstract: Techniques are provided for offloading the management of sensor data and generating custom views of sensor data. Sensor data received from a data network through a message is stored within storage managed by a computing device. A handle is generated to identify the sensor data. The sensor data within the message is replaced with the handle, and the message is transmitted to a device within the data network. The device may use handles of sensor data to request custom views of sensor data.

Abstract: Methods, non-transitory computer readable media, and devices that more effectively manage snapshots by creating a namespace including files described by stored file recipe objects and each comprising fragments, directories described by metadata in the file recipe objects and each comprising one or more of the files, and snapshots described by stored snapshot request objects. Content of one of the directories are identified based on an identification of corresponding ones of the file recipe objects that existed within the namespace at a specified time. At least one of the files, included in the identified content and existing within the namespace at the specified time, is accessed in response to one or more received requests. A garbage collection operation is periodically performed to delete the recipe objects that are marked for deletion by tombstone objects and are unreferenced by any of the snapshots as determined based on the snapshot request objects.

Abstract: A storage system includes data storage devices, bus conductors, and mobile reader/writer devices. Each of the storage devices is positioned between insulators, is at one of a plurality of locations on one of one or more shelf assemblies, and comprises a processor coupled to a memory and an interface device. One of the bus conductors is adjacent each of the insulators. Each of the reader/writer devices includes a transport apparatus, a processor and a memory. The transport apparatus is configured to move one of the reader/writer devices to one or more of the locations when engaged. The processor is coupled to the transport apparatus and the memory and is configured to execute machine executable code to: engage the transport apparatus to position one of the reader/writer devices to one of the locations in response to a received operation; couple power to one of the storage devices; and execute the operation.

Abstract: Embodiments use data shuttle devices to restore erasure-coded data in a distributed storage environment. In some embodiments, a first data shuttle is communicatively coupled to a first node of the storage environment. On the data shuttle, first restoration data is generated from a first erasure-coded data portion stored on the first node. The first data shuttle or a second data shuttle is communicatively coupled to a second node of the storage environment. On the data shuttle at the second node, second restoration data is generated from a second erasure-coded data portion stored on the second node. Subsequent to transporting the first or second data shuttle from at least one of the other nodes to a third node, a third erasure-coded data portion is restored at the third node. The third erasure-coded data portion is generated via an erasure-coding process from one or more of the first or second restoration data.
