Abstract: A data storage system can organize a semiconductor memory into a first data set and a second data set with a first queue populated with a first data access request from a host. An assignment of an arbitration weight to the first queue with an arbitration circuit corresponds with the first queue being skipped during a deterministic window based on the arbitration weight.

Abstract: A data storage system can optimize deterministic window operation of a data storage system where a host is connected to a data storage device via a system module having at least two controller inputs. A data access request can be stored in a first cache by the system module prior to analyzing an operational parameter of the system and generating a cache strategy that is directed to optimizing execution of the data access request with the two controller inputs during a deterministic window between the host and data storage device. The data of the data access request can be proactively moved to a second cache in accordance with the cache strategy to optimize the deterministic window performance.
