A method includes (a) receiving workload data for a data storage system, the data storage system having a plurality of processing cores, the data storage system being configured to operate according to any of a plurality of profiles, each of the plurality of profiles having a respective assignment of respective cores of the plurality of cores to particular storage roles of the data storage system, (b) for each profile of the plurality of profiles, simulating operation of the data storage system running a workload based on the received workload data using the assignment of respective cores of the plurality of cores to particular storage roles for that profile, thereby producing a set of utilization scores, (c) selecting a profile of the plurality of profiles based on the set of utilization scores, and (d) outputting an indication of the selected profile for use by the data storage system.

Intelligent core assignment

A method, apparatus and computer program product for providing pre-calculated performance simulation is presented. Performance simulations for a storage system are provided by selecting a subset of system configuration options from a large set of system configuration options. Simulation results for the subset of system configuration options are pre-calculated. The simulation results for the subset of system configuration options are loaded on a portable device. System configuration requirements for a customer are received and at least one system configuration option is selected from the subset of system configuration options based on the simulation results and the system configuration requirements for a customer.

Pre-calculated performance simulation

Described are techniques for selecting a storage pool configuration. A set of one or more candidate storage pool configurations is determined. For each of the candidate storage pool configurations of the set, a reliability calculation is performed to determine a reliability value indicating reliability of the candidate storage pool configuration. For each of the candidate storage pool configurations of the set, an availability calculation is performed to determine an availability value indicating availability of the candidate storage pool configuration. In accordance with selection criteria, one of the candidate storage pool configurations of the set for a first storage pool is selected. The selection criteria includes the availability value and the reliability value for each of the plurality of candidate storage pool configurations.
