Abstract
The examples described herein discuss various systems, software, devices, and methods for managing a primary command queue by ordering and/or reordering and distributing incoming commands based, at least in part, on positional information of one or more components of data storage devices. More specifically, in some embodiments, the examples discussed herein describe ordering and distributing incoming commands from a primary command queue in a position-aware manner that takes into account disk rotation (e.g., rotational position) and/or actuator head location for the various data storage devices of a data storage system enclosure. Among other benefits, ordering incoming commands at the primary command queue and distributing the ordered commands to individual device queues improves overall command execution latency.
