Abstract: A data storage system can connect a plurality of remote hosts to a plurality of die sets resident in a semiconductor memory. Execution of at least one data access command addressed by a remote host of the plurality of remote hosts can occur prior to a power interruption event being detected for at least one die set of the plurality of die sets. User-generated data associated with the at least one data access command may then be flushed to a predetermined location responsive to an available resource budget associated with the power interruption event.

Abstract: A data storage system can divide a semiconductor memory into a plurality of die sets prior to populating a die set queue with data access commands addressed by a remote host and having a first order. A command order strategy generated by a time-to-ready module organizes the data access commands to a second order that populate a channel queue and are executed as directed by the time-to-ready module in the second order.

Abstract: A data storage system can arrange semiconductor memory into a plurality of die sets where performance metrics of execution of a first data access command to a first die set and of a second data access command to a second die set are measured. A proactive strategy is generated to maintain consistent data access command execution performance with a quality of service module based on the measured performance metrics and a third data access command is altered, as directed by the proactive strategy, to prevent a predicted non-uniformity of data access command performance between the first die set and the second die set.
