A system and method for storing data in a memory device. The method includes transmitting, to a host, information indicative of a first allowable maximum size of a first namespace associated with a first IU and a second allowable maximum size of a second namespace associated with a second IU. The first and the second IUs may be of different sizes. The includes comprise receiving configuration information comprising one or more instructions to: generate a first L2P table associated with the first IU based on the first allowable maximum size, and generate a second L2P table associated with the second IU based on the second allowable maximum size and generating the first L2P table and the second L2P table based on the configuration information; and causing first data and second data to be stored in the first namespace and the second namespace using the first and second L2P tables respectively.

Example implementations relate to deduplication operations in a storage system. An example includes receiving a set of data units to be stored in persistent storage of a deduplication storage system, and recording the arrival order of the set of data units in a manifest. The example also includes, in response to determining that an average unit size of the set of data units is smaller than a minimum size threshold, identifying a first data unit that is smaller than the minimum size threshold. The example also includes generating an aggregated data unit including the first data unit and a second data unit, and, in response to determining that the size of the aggregated data unit is larger than a target size threshold, replacing, in the manifest, the first data unit and the second data unit with the aggregated data unit.

Allocation units having equal allocation unit sizes are formed for writing into erase blocks of a storage system. One or more of the allocation units are formed of at least a portion of two erase blocks. Data is written to the erase blocks forming the allocation units such that one of the erase blocks is open at a time during the writing of the data.

A system and method for improving program performance and reducing program cost by automatically providing and managing an appropriate memory pool cell size adapted to each executing application. The data is processed using a corresponding time series prediction model by collecting a time series of historical data for use with respect to a memory pool of an application over a period of time to predict a size of assignments for the application, and in particular, a predicted number of assignments and a corresponding predicted assignment unit size. A clustering-based approach is further applied to predict the size of an allocation of an application, using real-time execution for scaling, supplementation, and interpolation. A method runs another timing prediction model trained to predict adjustment parameters to refine a memory pool storage area size for processing a memory allocation request based on a predicted size of a memory unit and one or more application profile features associated with a requested application.

Techniques can include: receiving host write I / Os; and performing processing that persistently records the host write I / Os on a log device including a metadata log for storing metadata portions for the host write I / Os. The processing can include: aggregating, in a write aggregation queue, log write requests that write metadata portions for the host write I / Os in a segment of metadata log entries of the metadata log of the log device; and responsive to determining that i) the log write requests corresponding to the segment write an amount of metadata equal to a maximum size, or ii) a maximum amount of time has elapsed during said aggregating, sending an aggregated write request to the metadata log of the log device, wherein the aggregated write request writes the metadata portions to the segment of metadata log entries. The maximum size can denote an integrated unit size of the log device.
