Total Cost of Ownership (TCO) Model for Storage
Performance-based TCO provides a more accurate way to evaluate storage by measuring the cost of getting work done—not just the cost of infrastructure. Traditional models often overlook how performance, time to completion, and system efficiency directly impact total cost.
This page introduces the performance-based TCO model and shows how it can be applied. The diagram below outlines the key factors that influence cost, while the white paper and calculator enable you to evaluate real-world scenarios, quantify workload costs, and compare software and hardware-accelerated approaches.
What Goes Into a TCO Model?
Performance-based TCO reflects the full cost of running workloads by incorporating performance, time to completion, and resource utilization—not just infrastructure cost. As shown in the model, factors such as CPU usage, processing time, and data efficiency directly influence total cost.
A wide range of inputs contribute to TCO, including system performance, endurance, and total capacity. This model normalizes cost as TCO $ / TBe / rack / month, enabling consistent comparisons across deployments. Workload-specific factors such as capacity utilization, error encoding, replication, and data reduction can significantly impact results, while performance-driven analysis highlights how faster technologies, such as SSDs, can reduce total cost when meeting specific workload demands or SLAs.
Explore the Model and Apply It
The white paper introduces the performance-based TCO model and explains why traditional cost approaches fall short. The calculator puts that model into—allowing you to evaluate real-world scenarios, quantify workload costs, and compare software and hardware-accelerated approaches.
