  • Failure Prediction, Lead Time Estimation and Health Degree Assessment for Hard Disk Drives Using Voting Based Decision Trees
    Computers, Materials & Continua CMC, vol.60, no.3, pp.913-946, 2019 Failure Prediction, Lead Time Estimation and Health Degree Assessment for Hard Disk Drives Using Voting Based Decision Trees Kamaljit Kaur 1, * and Kuljit Kaur2 Abstract: Hard Disk drives (HDDs) are an essential component of cloud computing and big data, responsible for storing humongous volumes of collected data. However, HDD failures pose a huge challenge to big data servers and cloud service providers. Every year, about 10% disk drives used in servers crash at least twice, lead to data loss, recovery cost and lower reliability. Recently, the researchers have used SMART parameters to develop various prediction techniques, however, these methods need to be improved for reliability and real-world usage due to the following factors: they lack the ability to consider the gradual change/deterioration of HDDs; they have failed to handle data unbalancing and biases problem; they don’t have adequate mechanisms for health status prediction of HDDs. This paper introduces a novel voting-based decision tree classifier to cater failure prediction, a balance splitting algorithm for the data unbalancing problem, an advanced procedure for lead time estimation and R-CNN based approach for health status estimation. Our system works robustly by considering a gradual change in SMART parameters. The system is rigorously tested on 3 datasets and it delivered benchmarks results as compared to the state of the art. Keywords: Hard disk drive, lead time, health status, N-splitting algorithm, machine learning, deep learning, data storage, unbalancing problem. 1 Introduction The 21st century is the era of big data, cloud computing, and distributed networks.

  • To Fail Or Not to Fail: Predicting Hard Disk Drive Failure Time Windows
    To Fail Or Not To Fail: Predicting Hard Disk Drive Failure Time Windows Marwin Z¨ufle,Christian Krupitzer, Florian Erhard, Johannes Grohmann, and Samuel Kounev Software Engineering Group, University of W¨urzburg, W¨urzburg,Germany [email protected], [email protected], [christian.krupitzer;johannes.grohmann;samuel.kounev]@uni-wuerzburg.de Homepage: https://descartes.tools Abstract. Due to the increasing size of today's data centers as well as the expectation of 24/7 availability, the complexity in the administration of hardware continuously increases. Techniques as the Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) support the monitor- ing of the hardware. However, those techniques often lack algorithms for intelligent data analytics. Especially, the integration of machine learning to identify potential failures in advance seems to be promising to reduce administration overhead. In this work, we present three machine learning approaches to (i) identify imminent failures, (ii) predict time windows for failures, as well as (iii) predict the exact time-to-failure. In a case study with real data from 369 hard disks, we achieve an F1-score of up to 98.0% and 97.6% for predicting potential failures with two or mul- tiple time windows, respectively, and a hit rate of 84.9% (with a mean absolute error of 4.5 hours) for predicting the time-to-failure. Keywords: Failure prediction · S.M.A.R.T. · Machine learning · Label- ing methods · Classification · Regression · Cloud Computing. 1 Introduction Large IT companies like Google, Amazon, Microsoft, and IBM have millions of servers worldwide. The administration of those servers is an expensive and time-consuming task.
