Abstract
Described are techniques for simulation of a data storage system configuration. The simulation state reflects the data storage system configuration in accordance with an application programming interface (API) model. API calls result in reading existing data storage system configuration data and/or modifying the configuration data by execution of one or more low level calls. A daemon may operate in a simulation mode in which the low level calls are simulated rather than resulting in communications with a data storage system when operating in a non-simulation mode. A low level cache is used to store simulated values returned from the data storage system microcode. A high level cache is used to store API call return data. A seed file is used to initialize the simulation state.
