Simulation of data storage and processing centers taking into account economic components

The article presents an overview of existing and developing methods for simulation of storage and processing data centers, taking into account the cost of equipment, electricity, telecommunications and much more. The main purpose of these methods is to find the optimal configuration of the necessary equipment for the centers scale-up, taking into account economic factors. Based on simulation results, it will be possible to optimize the data processing costs. Such optimization is necessary due to the growing computational needs for processing and storage of experimental data in all fields of science, in particular, high energy physics. The cost models, which developed at JINR and CERN, are considered.
