Data centers have evolved dramatically in recent years, due to the advent of social networking services, e-commerce and cloud computing. The conflicting requirements are the high availability levels demanded against the low sustainability impact and cost values. The approaches that evaluate and optimize these requirements are essential to support designers of data center architectures. Our work aims to propose an integrated approach to estimate and optimize these issues with the support of the developed environment, Mercury. Mercury is a tool for dependability, performance and energy flow evaluation. The tool supports reliability block diagrams (RBD), stochastic Petri nets (SPNs), continuous-time Markov chains (CTMC) and energy flow (EFM) models. The EFM verifies the energy flow on data center architectures, taking into account the energy efficiency and power capacity that each device can provide (assuming power systems) or extract (considering cooling components). The EFM also estimates the sustainability impact and cost issues of data center architectures. Additionally, a methodology is also considered to support the modeling, evaluation and optimization processes. Two case studies are presented to illustrate the adopted methodology on data center power systems.

“…Therefore, formal verification of a DRBD model is an essential step in developing a correct system reliability model for the I evaluation of a system's reliability. In our recent work, we demonstrated some preliminary results on how to formally verify a DRBD model using colored Petri nets (CPN) [4][5], which provide the formal semantics for DRBD models. The approach follows the basic philosophy of recent efforts on converting a UML (Unified Modeling Language) diagram to Petri nets for formal verification [6].…”

“…Recently, an extension to RBD, called dynamic reliability block diagram (DRBD) [4][5], was introduced with new controller constructs that support modeling dynamic, dependent and redundant relationships between components in a computer-based system. Although it has been shown that the DRBD approach is very effective in modeling a system's dynamic reliability properties, subtle flaws in it can be easily introduced due to its modeling complexity.…”

Abstract-Computer system reliability is conventionally modeled and analyzed using techniques such as fault tree analysis (FTA) and reliability block diagrams (RBD), which provide static representations of system reliability properties. A recent extension to RBD, called dynamic reliability block diagrams (DRBD), defines a framework for modeling dynamic reliability behavior of computer-based systems. However, analyzing a DRBD model in order to locate and identify design errors, such as a deadlock error or faulty state, is not trivial when done manually. A feasible approach to verifying it is to develop its formal model, and then analyze it using programmatic methods. In this paper, we first define a reliability markup language (RML) that can be used to formally describe DRBD models. Then we present an algorithm that automatically converts a DRBD model into a colored Petri net (CPN). We use a case study to illustrate the effectiveness of our approach and demonstrate how system properties of a DRBD model can be verified using an existing Petri net tool. Our formal modeling approach is compositional, thus it provides a potential solution to automated verification of DRBD models. Index Terms-System
