Exemplary methods, apparatuses, and systems include aggregating a plurality of memory status commands. Each command of the plurality of memory status commands is assigned a corresponding bit on a memory interface. The plurality of memory status commands are sent in parallel as an aggregate status command to one or more memory components via the memory interface.

Embodiments of the present disclosure provide a system for testing multicore firmware (FW) in a memory system and a method thereof. A test system includes a test device and a storage device including a plurality of flash translation layer (FTL) cores, each FTL core associated with multiple memory blocks. The test device generates test preconditions for the plurality of FTL cores and provides the test preconditions to the plurality of FTL cores, the test preconditions being different from each other. Each of the plurality of FTL cores performs one or more test operations based on a corresponding test precondition of the test preconditions.

Embodiments described herein are generally directed to selective multithreaded execution of memory training by CPU sockets. In an example, a memory configuration and a current phase of execution of memory training for each of multiple CPU sockets of a computer system is received. Based on the memory configuration and the current phase of execution of each of the CPU sockets an estimated power usage across all CPU sockets may be determined. Based on the estimated power usage and a power consumption threshold (e.g., PTAM or PA), performance of the current phase of execution of one or more CPU sockets may be selectively released for one or more channels of the one or more CPU sockets.

Various embodiments comprise systems and methods to monitor operations of a data pipeline. In some examples, a data pipeline receives data inputs, processes the data inputs, and responsively generates and transfers data outputs. Data monitoring circuitry monitors the operations of the data pipeline circuitry, identifies an input change between an initial one of the data inputs and a subsequent one of the data inputs, and identifies an output change between an initial one of the data outputs and a subsequent one of the data outputs. The data monitoring circuitry correlates the input change to the output change, determines a quality threshold for the output change based on the correlation, and determines when the output change falls below the quality threshold. When the output change falls below the quality threshold, the data monitoring circuitry generates and transfers an alert that indicates the input change and the output change.

A method and system for initiating a garbage collection request. Historical data representative of a level of initiated I/O requests is acquired. A first operational state and a second operational state are determined based on the historical data. The first operational state and second operational state are expressed in an indication of the level of initiated I/O requests to be processed. A number of currently initiated I/O requests is acquired. A determination is made as to whether the number of currently initiated I/O requests is indicative of the first operational state or the second operational state. If the computer system is in the first operational state, the garbage collection request is initiated.

A method for managing memory within a computing system. The method includes one or more computer processors identifying a range of physical memory addresses that store a first data. The method further includes determining whether a second data is stored within the range of physical memory addresses that stores the first data. The method further includes responding to determining that the second data is stored within the range of physical memory addresses that store the first data, by determining whether a process accessing the second data is identified as associated with a side-channel attack. The method further includes responding to determining that the process accessing the second data is associated with the side-channel attack, by initiating a response associated with the process accessing the second data.

A method for status signaling in a non-volatile memory including a plurality of logical units (LUNs), each of the plurality of LUNs having a status terminal coupled to a common status terminal of the non-volatile memory and a data bus coupled to a common data bus of the non-volatile memory. The method including performing, by a first LUN of the plurality of LUNs, a first set of one or more operations; completing, by the first LUN of the plurality of LUNs, the first set of one or more operations; and sending, by the first LUN via the common terminal, a pulse to a controller responsive to completing the first set of one or more operations.

In an approach for generating differentiated workload telemetry data, a processor corresponds one or more services with a workload related telemetry generating an event emitter. A processor performs a correlation analysis of corresponding relationship and connection among connected resources and current traffic into and out of the one or more services. A processor labels domain context for each telemetry event. A processor communicates each telemetry event to a global event handler. A processor performs a cross-correlation in real-time of telemetry data with the global event handler. A processor updates a real-time differentiated workload report.

For each seek command of a plurality of seek commands of a hard disk drive, a correction value is determined that adjusts an access time of the seek command. The correction value includes a scaling factor that adjusts an energy variable. The scaling factor is based on a power target of the hard disk drive, and the energy variable may represent an energy used in the seek command as a time value. The seek commands are sorted in a command queue by the adjusted access times. The seek commands are executed by a controller of the hard disk drive based on the sorting within the command queue.

In some examples, a computing system receives an indication of an increased workload portion to be added to a workload of a storage system, the workload comprising buckets of operations of different characteristics. The computing system computes, based on quantities of operations of the different characteristics in the workload, factor values that indicate distribution of operations of the increased workload portion to the buckets of operations of the different characteristics, and distributes, according to the factor values, the operations of the increased workload portion into the buckets of operations of the different characteristics.
