Abstract: Systems and methods for active power management are described. In one embodiment, the systems and methods include obtaining power dissipation metrics for a plurality of components under one or more operating scenarios, generating a reference dissipation model based on the power dissipation metrics of the plurality of components, and implementing the reference dissipation model in a storage system to make component scheduling decisions in relation to power management of the storage system. In some embodiments, the storage system includes any combination of a hard disk drive, a solid state drive, a hybrid drive, and a system of multiple storage drives.

Abstract: A data storage system may have a plurality of memory cells located in different data storage devices that are arranged into a plurality of logical namespaces with each logical namespace configured to be sequentially written and entirely erased as a single unit. An asymmetry strategy may be proactively created with the asymmetry module in response to data access activity to the logical namespaces by the asymmetry module. A new mode, as prescribed by the asymmetry strategy, is entered for at least one logical namespace in response to an operational trigger being met. The new mode changes a timing of at least one queued data access request to at least one logical namespace.

Abstract: A system can log data access activity to a memory array with a metadata module while the memory array is logically divided into multiple namespaces. A workload can be determined for each namespace by the metadata module and a metadata strategy can be created with the metadata module in view of the respective namespace workloads. A first metadata and second metadata may be generated for respective first and second user-generated data for storage into a first namespace of the multiple namespaces. The first metadata can be compressed with a compression level prescribed by the metadata strategy in response to a detected or predicted workload to the first namespace before the first metadata, second metadata, first user-generated data, and second user-generated data are each stored in the first namespace.

Abstract: A method operable with the storage device includes determining a workload to the storage device based on host Input/Output (I/O) requests to the storage device. When the workload is above a threshold, a first portion of the storage device is selected for garbage collection based on the I/O requests. Otherwise, when the workload is below the threshold, a second different portion of the storage device is selected for garbage collection based on a storage ability of the second portion of the storage device.

Abstract: Systems and methods for limiting performance variation in a storage device are described. Storage devices receive work requests to perform one or more operations from other computing devices, such as a host computing device. Completing the work requests may take a response time. In some embodiments, if the response time of executing the work request exceeds a threshold, the storage device may assign additional computing resources to complete the work request.

Abstract: A data storage system may have a data storage device with a memory arranged into a plurality of logical namespaces. A power module can be connected to the plurality of logical namespaces and configured to transition at least one memory cell in response to a workload computed for a namespace of the plurality of the logical namespaces to maintain a power consumption of 8 watts or less for the data storage device.
