The document discusses Mainline's Storage Investment Analysis service which calculates the total cost of ownership (TCO) and loaded cost per terabyte of a company's storage infrastructure. The service delivers a presentation of the results, a TCO and ROI calculator, and optionally provides a cost breakdown per storage service class. It helps clients improve infrastructure utilization and identify projects that do not achieve a return on investment. Mainline can also incorporate the analysis into a larger storage assessment to further enhance results.
