Performance, Reliability, and Availability Evaluation of Computational Systems, Volume 2: Reliability, Availability Modeling, Measuring, and Data Anal

This textbook intends to be a comprehensive and substantially self-contained two-volume book covering performance, reliability, and availability evaluation subjects. The volumes focus on computing systems, although the methods may also be applied to other systems. The first volume covers Chapter 1 to Chapter 14, whose subtitle is Performance Modeling and Background. The second volume encompasses Chapter 15 to Chapter 25 and has the subtitle Reliability and Availability Modeling, Measuring and Workload, and Lifetime Data Analysis.

This text is helpful for computer performance professionals for supporting planning, design, configuring, and tuning the performance, reliability, and availability of computing systems. Such professionals may use these volumes to get acquainted with specific subjects by looking at the particular chapters. Many examples in the textbook on computing systems will help them understand the concepts covered in each chapter. The text may also be helpful for the instructor who teaches performance, reliability, and availability evaluation subjects. Many possible threads could be configured according to the interest of the audience and the duration of the course. Chapter 1 presents a good number of possible courses programs that could be organized using this text.

Volume II is composed of the last two parts. Part III examines reliability and availability modeling by covering a set of fundamental notions, definitions, redundancy procedures, and modeling methods such as Reliability Block Diagrams (RBD) and Fault Trees (FT) with the respective evaluation methods, adopts Markov chains, Stochastic Petri nets and even hierarchical and heterogeneous modeling to represent more complex systems. Part IV discusses performance measurements and reliability data analysis. It first depicts some basic measuring mechanisms applied in computer systems, then discusses workload generation. After, we examine failure monitoring and fault injection, and finally, we discuss a set of techniques for reliability and maintainability data analysis.

本教科書旨在成為一本全面且相當自成一體的兩卷本，涵蓋性能、可靠性和可用性評估主題。這些卷專注於計算系統，儘管這些方法也可以應用於其他系統。第一卷涵蓋第1章到第14章，其副標題為性能建模和背景。第二卷包括第15章到第25章，副標題為可靠性和可用性建模、測量和工作負載以及生命週期數據分析。

這本教材對於支持計算系統的性能、可靠性和可用性的規劃、設計、配置和調整的計算機性能專業人員非常有幫助。這些專業人員可以通過查看特定章節來熟悉特定主題。教科書中關於計算系統的許多示例將幫助他們理解每個章節涵蓋的概念。這本教材對於教授性能、可靠性和可用性評估主題的教師也很有幫助。根據受眾的興趣和課程的持續時間，可以配置許多可能的主題。第1章介紹了使用本教材可以組織的許多可能的課程計劃。

第二卷由最後兩個部分組成。第三部分通過涵蓋一組基本概念、定義、冗余程序和建模方法（如可靠性塊圖和故障樹）以及相應的評估方法，採用馬可夫鏈、隨機Petri網甚至分層和異構建模來表示更複雜的系統，來討論可靠性和可用性建模。第四部分討論性能測量和可靠性數據分析。首先描述了在計算系統中應用的一些基本測量機制，然後討論了工作負載生成。之後，我們檢查故障監控和故障注入，最後，我們討論了一套可靠性和可維護性數據分析技術。
