    Abstract: Described are examples for storing, in a first zone cache, one or more logical blocks (LBs) corresponding to a data chunk, writing, for each LB in the data chunk, a cache element of a cache entry that points to the LB in the first zone cache, where the cache entry includes multiple cache elements corresponding to the multiple LBs of the data chunk, writing, for the cache entry, a table entry in a mapping table that points to the cache entry, and when a storage policy is triggered for the cache entry, writing the multiple LBs, pointed to by each cache element of the cache entry, as contiguous LBs in an isolation block for the data chunk in a second zone stream, and updating the table entry to point to the isolation block in the second zone stream.

    Abstract: A computing system including one or more processing devices configured to detect a congestion condition occurring at a first storage node located in a storage network of a distributed storage system. The one or more processing devices are further configured to obtain respective first access rate data for a first plurality of data objects stored at the first storage node. Based at least in part on the first access rate data, the one or more processing devices are further configured to flag a first data object as a high-access-rate data object. The one or more processing devices are further configured to compute a transfer path between the first storage node and a second storage node in the storage network. The one or more processing devices are further configured to transfer the high-access-rate data object from the first storage node to the second storage node along the transfer path.

    Abstract: Described are examples for performing garbage collection in a file system having multiple zones of data. A garbage rate associated with an amount of invalid data in the zone can be computed for each zone of the multiple zones in the file system. One or more candidate zones, of the multiple zones, can be determined for garbage collection based on the garbage rate and a sequence number assigned to the zone. Garbage collection of the one or more candidate zones in the file system can be performed.

    Abstract: Described are examples for storing data on a storage device, including storing, in a live write stream cache, one or more logical blocks (LBs) corresponding to a data segment, writing, for each LB in the data segment, a cache element of a cache entry that points to the LB in the live write stream cache, where the cache entry includes multiple cache elements corresponding to the multiple LBs of the data segment, writing, for the cache entry, a table entry in a mapping table that points to the cache entry, and when a storage policy is triggered for the cache entry, writing the multiple LBs, pointed to by each cache element of the cache entry, to a stream for storing as contiguous LBs on the storage device, and updating the table entry to point to a physical address of a first LB of the contiguous LBs on the storage device.

    Abstract: A computing system for verifying data integrity is provided, including a host device comprising a memory controller, and a storage device. The memory controller receives original data blocks, each having an associated initial CRC value. The memory controller then segments and recombines the data blocks into logic blocks. The storage device is configured to write the logic blocks to its non-volatile memory of the storage device in the write operation, calculate a new logic block (LB) CRC value for each logic block, and calculate a combined LB CRC value. After the write operation, the memory controller combines duplicated copies of a given CRC value for each of the original data blocks, then combines them together to calculate a combined segments CRC value, and compares the combined segments CRC value to the combined LB CRC value. When the combined CRC values match, a verification response is generated verifying data integrity.

    Abstract: A network storage system comprises a first application node, storage nodes, and a switch fabric comprising switches providing data paths. Each data path connects the first application node to a storage node of the plurality of storage nodes. The system further comprises a control plane software agent. The control plane software agent configures the network storage system to receive, via the first application node, a request for storing a file, select a first storage node, initialize a file identifier for the file based on a network topology of the switch fabric and the storage nodes, and store the file on the first storage node. The file identifier describes the first storage node, a storage location in the first storage node, and a first data path of the data paths. The first data path includes a first set of switches connecting the first application node to the first storage node.
