Abstract: Aspects of the present disclosure configure a system component, such as memory sub-system controller, to dynamically generate Redundant Array of Independent Nodes (RAIN) parity information for zone-based memory allocations. The RAIN parity information is generated for a given zone or set of zones on the basis of whether the given zone or set of zones satisfy a zone completeness criterion. The zone completeness criterion can represent a specified size such that when a given zone reaches the specified size, the parity information for that zone is generated.

The SSD has a host interface configured to receive at least read commands and write commands from an external host system. The SSD has memory cells formed on at least one integrated circuit die, and a processing device configured to control executions of the read commands to retrieve data from the memory cells and executions the write commands to store data into the memory cells. The firmware is executable in the SSD to allocate storage resources not used or allocated by the host system to support proof of space activities and dynamically return the allocated storage resources when execution of a command from the host system needs additional storage resources.

Abstract: An input/output (I/O) write request directed at memory devices is received by a processing device. The write request includes a data object. The memory devices include groups of memory cells corresponding to sequential logical addresses. The data object is appended to a compound data object associated with one of the memory devices. The compound data object is associated with the groups of memory cells. A first group of memory cells is in the not-full state, and one or more subsequent, in an order corresponding to the sequential logical addresses, groups of memory cells is identified as a free group of memory cells. The compound data object is caused to be written to the groups of memory cells, resulting in the full state of the first group of memory cells and resulting in the not-full state of at least one of the one or more subsequent groups of memory.

Abstract: A host system to query, during booting up of the host system, a superblock size in a connected memory sub-system. The host system can place write requests into separate streams and send the streams to the memory sub-system to store data of the write requests into separate sets of superblocks for the streams respectively. The host system can allocate, a plurality of log buffers for the streams respectively and record, into the log buffers, sequences of logical addresses as in the streams respectively. The host system can trim a stream, among the plurality of streams, by issuing commands to the memory sub-system to erase, according to the superblock size, an amount of data from a portion of a sequence of logical addresses recorded in a log buffer for the stream, causing the memory sub-system to free at least one superblock.

Abstract: A memory sub-system can determine a block granularity for an input/output (I/O) data stream received from a host system. The memory sub-system can determine that the block granularity is different than a memory block granularity of a first memory region in a first namespace of the one or more memory devices, where the first memory region is to store the I/O data stream. The memory sub-system can accumulate blocks from the I/O data stream in a second memory region in a second namespace of the one or more memory devices. Responsive to a capacity of the accumulated blocks in the second memory region satisfying a threshold criterion, the memory sub-system can migrate the accumulated plurality of blocks from the second memory region to the first memory region.
