    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: Systems and methods for space allocation for block device compression are provided. In particular, a computing device may receive an allocation request to write the compressed data, select a range list adequate for serving the allocation request from a plurality of range list, dequeue a range entry from the selected range list to allocate free space for the compressed data, and allocate the free space corresponding to the range entry to the compressed data to serve the allocation request.

    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: A method for accessing blocks of a solid state drive is described. A starting position is received, where the starting position identifies a first block of a contiguous block region within a namespace of the solid state drive. The contiguous block region is to be accessed according to a single input/output operation and the namespace comprises two dimensions of logical address space with respective indices for indexing blocks within a corresponding dimension of the logical address space. A first dimensional identifier that identifies a size of the contiguous block region in a first dimension of the namespace is received. A second dimensional identifier that identifies a size of the contiguous block region in a second dimension of the namespace is received. Blocks of the contiguous block region are accessed in response to the single input/output operation according to the starting position, the first dimensional identifier, and the second dimensional identifier.
