PERFORMANCE TUNING A DATA STORAGE SYSTEM BASED ON QUANTIFIED SCALABILITY

摘要

A method of tuning performance of a data storage system includes calculating an estimate of parallel fraction and speedup characteristic for a data storage application executed by the data storage system. The estimate is calculated using linear regression of values (1/N, 1/X_N) that are generated from trial runs of the data storage application processing a workload using respective different numbers N of CPU cores to obtain corresponding performance values X_N. The method further includes configuring the data storage system to execute the data storage application using a number of CPU cores based on the estimate of parallel fraction and speedup characteristic.
