Autonomous core affinity

A storage system comprising:

• a plurality of compute nodes that manage access to non-volatile drives;
• a model of storage system workload configurations, each workload configuration comprising counts of tasks that characterize a different workload and exclusive allocations of processor cores to emulations for servicing the respective workload;
• a task count monitor configured to count the tasks performed to service a current actual workload;
• a workload forecaster configured to forecast a change in the current actual workload based on the counted tasks;
• and
• a core allocation updater configured to select and implement one of the workload configurations of the model based on comparison of the counts of tasks associated with the workload configurations and the forecasted change in the current actual workload based on the counted tasks.

A non-transitory computer-readable storage medium storing instructions that when executed by a computer perform a method comprising:

• creating a model of storage system workload configurations, each workload configuration including counts of tasks that characterize a different workload and exclusive allocations of processor cores to emulations for servicing the respective workload;
• counting the tasks performed to service a current actual workload;
• forecasting a change in the current actual workload based on the counted tasks;
• and
• selecting and implementing one of the workload configurations of the model based on comparison of the counts of tasks associated with the workload configurations and the forecasted change in the current actual workload based on the counted tasks.
