Aspects of the present disclosure relate to data cache management. In embodiments, a storage array's memory is provisioned with cache memory, wherein the cache memory includes one or more sets of distinctly sized cache slots. Additionally, a logical storage volume (LSV) is established with at least one logical block address (LBA) group. Further, at least one of the LSV's LBA groups is associated with two or more distinctly sized cache slots based on an input/output (IO) workload received by the storage array.

Aspects of the present disclosure relate to data cache management. In embodiments, a logical block address (LBA) bucket is established with at least one logical LBA group. Additionally, at least one LBA group is associated with two or more distinctly sized cache slots based on an input/output (IO) workload received by the storage array. Further, the association includes binding the two or more distinctly sized cache slots with at least one LBA group and mapping the bound distinctly sized cache slots in a searchable data structure. Furthermore, the searchable data structure identifies relationships between slot pointers and key metadata.

A plurality of work items are processed through a processing pipeline comprising a plurality of stages in processing logic. The processing of a work item includes: (i) reading data in accordance with a memory address associated with the work item, (ii) updating the read data, and (iii) writing the updated data in accordance with the memory address associated with the work item. The method includes processing a first work item and a second work item through the processing pipeline, wherein the processing of the first work item through the pipeline is initiated earlier than the processing of the second work item, and where it is determined that the first and second work items are associated with the same memory address, first updated data of the first work item is written to a register in the processing logic, and the processing of the second work item comprises reading the first updated data from the register instead of reading data from the memory.

Disclosed is a computer implemented method to manage a cache, the method comprising, determining that a primary application opens a first file, wherein opening the first file includes reading the first file into a file cache from a storage. The method also includes, setting a first monitoring variable in the primary application process proc structure, wherein the first monitoring variable is set in response to the primary application opening the first file, and the first monitoring variable records a set of operations completed on the first file by the primary application. The method comprises a first read of the first file being at a beginning of the first file. The method includes identifying that the first file is read according to a pattern that includes reading the first file sequentially and reading the first file entirely and removing the first file from the file cache.

A garbage data scrubbing method includes obtaining an input/output (IO) busy/idle status of a terminal at a current moment, where the IO busy/idle status includes a busy state and an idle state. When the IO busy/idle status of the terminal at the current moment is the idle state, a discard message is delivered to a storage device, where the discard message includes an initial address and a size of to-be-scrubbed physical space in the storage device, and where the discard message is used to unbind a mapping relationship between a physical address of the to-be-scrubbed physical space and a corresponding logical address.

A method includes determining that a ratio of valid data portions to a total quantity of data portions of a block of memory cells is greater than or less than a valid data portion threshold and determining that health characteristics for the valid data portions of the block of memory cells are greater than or less than a valid data health characteristic threshold. The method further includes performing a first media management operation on the block of memory cells in response to determining that the ratio of valid data portions to the total quantity of data portions is greater than the valid data portion threshold and performing a second media management operation on at least a portion of the block of memory cells in response to determining that the ratio of valid data portions to the total quantity of data portions is less than the valid data portion threshold and the health characteristics for the valid data portions are greater than the valid data health characteristic threshold.

The various embodiments disclose an electronic device including: a storage including a non-volatile memory having a buffer space and a storage space, a storage device controller, and a storage interface, and a processor. According to various embodiments, the processor may be configured to perform control to determine whether the storage supports a high speed data storage mode using a buffer space of a non-volatile memory of the storage, activate a function of writing data buffered in the buffer space of the non-volatile memory into a storage space of the non-volatile memory based on the storage interface operating in a first state based on the storage supporting the high speed data storage mode, and transition the storage interface of the storage to the first state based on no request to the storage being generated during a predetermined time period based on the storage interface operating in a second state.

A method for storing measurement data detected by a sensor and indicative of an analyte in a body fluid sample using a system having a processor and a memory. First and second measurement data indicative of first and second measurement values measured by a sensor, respectively, are provided. A relative measurement value is determined by the processor and is indicative of a value difference between the first and second measurement values. The first measurement value is stored in a first storage area having a first storage size in the memory. The relative measurement value is stored in a second storage area having a second storage size in the memory that is smaller than the first storage size. An indicator is also stored in the memory and is assigned to the relative measurement storage data in the memory and is indicative of a characteristic of the relative measurement storage data.
