Abstract: Disclosed deduplication techniques at a distributed data storage system guarantee that space reclamation will not affect deduplicated data integrity even without perfect synchronization between components. By understanding certain “behavioral” characteristics and schedule cadences of backup operations that generate backup copies received at the distributed data storage system, data blocks that are not re-written by subsequent backup copies are pro-actively aged, while promoting continued retention of data blocks that are re-written. An expiry scheme operates with block-level granularity. Each unique deduplicated data block is given an expiry timeframe based on the block's arrival time at the distributed data storage system (i.e., when a backup copy supplies the block) and further based on backup frequencies of the various virtual disks referencing a unique system-wide identifier of the block, which is based on the block's hash value. Communications between components are kept to an as-needed basis.

Abstract: A method and an apparatus for Bluetooth connection are disclosed. A first Bluetooth connection can be established between a first node of multiple data receiving nodes and a data source, the multiple data receiving nodes can share a data packet transmitted by the data source via the first Bluetooth connection, and a second node can be selected according to a preset rule from among the multiple data receiving nodes to feed back a response signal to the data source. In a method and an apparatus, the multiple data receiving nodes can be regarded as a whole, which share a data packet transmitted from the data source and jointly maintain the first Bluetooth connection, and only one of the multiple data receiving nodes is selected to feed back a response signal. Conforming to Bluetooth communication protocols, a method and an apparatus can meet the demanding requirements on hardware resources of a Bluetooth connection among a data source and multiple data receiving nodes.

Abstract: A distributed data storage system comprises features for integration with application orchestrators such as Kubernetes, and includes a proprietary Container Storage Interface (CSI) driver. Features include setting snapshot scheduling and retention policies, and a “container data mover” that replicates data from a source to a distinct destination distributed data storage system. The migration may be configured one-to-one, one-to-many, unidirectional, and/or bi-directional. Metadata-based snapshots and metadata-based changed block tracking identify payload data to move from source to destination within application orchestrator frameworks at both ends. Payload data is migrated from source to destination using different techniques than those used for migrating metadata, e.g., kernel-to-kernel for copying payload data versus ordinary metadata writes. An illustrative barrier logic ensures that the migration follows a controlled progression of operations.

Abstract: The present invention relates to a receiver-centric transmission system for IoT systems, such as lighting networks, with combo protocol radio chips that share a single radio front-end for two or more transmission protocols of different network technologies while preventing unacceptable performance degradations in one or both protocol modes. The receiver-centric approach allows implementation of two networks with acceptable performances on one single radio chip per node rather than requiring two radio chips per node.
