Abstract: Aspects of the disclosure relate to improved techniques for managing a data storage device (DSD) pool, and in particular the selecting of DSDs based on commands distribution and latencies among the command queues in the DSDs. In some aspects, a DSD may have multiple queues that enable the DSD to perform certain commands (e.g., write commands and/or read commands) in parallel. Thus, such DSD has various head-of-line blocking latencies based on which queue the command is directed to. A storage management device can reduce the command latency of the DSDs, for example, based on queue information (e.g., head-of-line blocking, parallel queue utilization, etc.) learned from the DSDs.

Abstract: Aspects directed toward data storage management are provided. A storage management device is connected to data storage devices (DSDs) that form a virtual storage pool (VSP), where the storage management device is configured to increase the overall performance of the VSP, as well as the lifespans of the individual DSDs. The storage management device can be configured to learn about the over-provisioning (OP) information of each DSD and strategically select the DSD to send write commands or data based on the OP information. The storage management device can be configured to borrow spare OP capacity from a DSD and use the borrowed capacity to expend the exported/logical capacity of the DSD.

Abstract: A programming order of memory dies of a metablock is typically fixed. However, in some storage architectures, this may cause performance bottlenecks. As such, the programming order of the memory dies may be altered to reduce or eliminate performance bottlenecks.

Abstract: In a non-volatile memory system that initially writes data in a binary format and then folds the stored data into a multi-level format, transfers of host data from the memory controller to the memory dies of the system are performed during both foggy and fine phases of the multi-level programming as data latches are released, allowing the transfer times to be hidden behind the programming. To improve data throughput one sub-set of the memory dies perform their foggy phase programming while another sub-set of the memory dies perform their fine phase programming, resulting in non-overlapping transfer windows for host data transfers for the two sub-sets of memory dies.
