Abstract: Mechanisms for controlling a solid-state drive (SSD), including: determining a workload type of the SSD using a hardware processor; determining an available bandwidth of the SSD based on at least the workload type; determining a number of host requests allowed to be processed during a current time interval based at least on the available bandwidth and a target moving average of flash translation layer (FTL) relocation source bands of the SSD; determining a number of relocations allowed to be performed in the SSD during the current time interval based at least on a number of host requests that were allowed to have been processed in a previous time interval, the target moving average, and an actual moving average of FTL relocation source bands of the SSD; and controlling the SSD to process the number of host requests and perform the number of relocations during the current time interval.

Abstract: Devices and related methods for performing background data refresh (BDR) are provided herein, where the device includes (1) memory with a plurality of memory bands and (2) processing circuitry. The processing circuitry is configured to determine information about each memory band of the plurality of memory bands, to determine an available bandwidth, determine a target refresh rate, and to determine one or more memory partitions to be relocated based on the information and the target refresh rate. The processing circuitry is further configured to cause one or more memory partitions to be relocated in the memory based on the available bandwidth.

Abstract: Mechanisms, including systems, methods, and media, for tuning a solid-state drive (SSD) are provided, the mechanisms including: providing as an input to a first neural network (NN) current parameter settings (PSs) of the SSD; receiving as an output from the first NN at least one adjustment to the current PSs; based on the at least one adjustment, adjusting the current PSs of the SSD so that the SSD is using adjusted PSs; causing the SSD to execute a workload using the adjusted PSs; determining performance data of the SSD while executing the workload; determining a reward value based on the performance data; and back propagating the first NN based on the reward value.

Abstract: Read Quality of Service (rQoS) in the solid state drive is improved by reducing latency for host random read workloads. Host read operations for random read workloads are prioritized in the solid state drive over program operations for garbage collection to reduce latency for random read workloads. The program time (tProg) and other associated latencies such as program-suspend-resume overhead, and firmware process overhead to dispatch the program are minimized by minimizing the number of program commands used for garbage collection while the solid state drive is performing read operations for a random read workload for a host read operation, allowing the solid state drive to prioritize host read operations for random read workloads while ensuring that there is no impact to the amount of written data that is on the solid state drive.
