  • Preparing for Future Data Center Professionals: Integrating Storage Technology Into the Computer Information Technology Curriculum
    Session S2E Preparing for Future Data Center Professionals: Integrating Storage Technology into the Computer Information Technology Curriculum Wei Hao, Hetal Jasani, Traian Marius Truta Northern Kentucky University, [email protected], [email protected], [email protected] Abstract -Information brings economic value to the To address the above problems, we have developed a new customers and data is the "soul" of the enterprise. Data course entitled CIT 465/565 - Storage Administration, for centers are playing more and more important roles in senior undergraduate students majoring in CIT and for the enterprises. Storage technology is one of the graduate students in the Master of Science in Computer fundamental technologies behind data centers. The Information Technology (MSCIT) at NKU. Since both our storage knowledge and skills are needed for data center CIT programs emphasize the hands-on learning, we have professionals. Thus, we have developed a new course, developed not only lecture components but also laboratory components for the course. The lecture components are Storage Administration, for Computer Information designed to cover three parts: storage fundamentals, storage Technology (CIT) major students at Northern Kentucky networks, and emerging technologies and data centers. The University (NKU). Since our CIT program emphasizes storage fundamentals part focuses on the fundamental hands-on learning, we have developed the course based storage concepts, such as storage devices, disk interfaces, on hands-on laboratory components. The laboratory disk geometry, disk partitions, disk performance, files components are developed based on open source systems, Redundant Array of Independent Disks (RAID), software and simulator software. In this paper, we hot swap, Logical Volume Management (LVM), and storage describe the hands-on laboratory components in details.

    Assessment of Current Health and Remaining Useful Life of Hard Disk Drives A Thesis Presented by Yogesh G. Bagul to The Department of Mechanical and Industrial Engineering in partial fulfillment of the requirements for the degree of Master of Science in Computer Systems Engineering Northeastern University Boston, Massachusetts USA January 2009 Northeastern University Graduate School of Engineering Thesis Title: Assessment of Current Health and Remaining Useful Life of Hard Disk Drives Author: Yogesh G. Bagul Department: Mechanical and Industrial Engineering Department Approved for Thesis Requirement of the Master of Science Degree ii © 2009 Yogesh G. Bagul iii ACKNOWLEDGEMENTS I would like to express my sincere gratitude to my thesis advisor, Dr. Ibrahim Zeid, for his guidance and support. I would also like to thank Dr. Sagar Kamarthi for his inspiration and guidance. I learned many things related to research from both of them. Their truly scientist intuition and an oasis of ideas always inspired and motivated me to fulfill their expectations. I would also like to thank the faculty and staff of Mechanical and Industrial Engineering Department for their timely support. I would also like to thank Tom Papadopoulos and James Jones for all the technical help they did. Also thanks to the Northeastern University for awarding me a Stipended Graduate Assistantship and providing me with the financial means to complete this project. I cannot end without thanking my family, especially Lt Cdr Rahul (my brother), on whose constant encouragement and love I have relied throughout my time at the Northeastern University. My successful completion of MS thesis would not have been possible without their loving support, caring thoughts, superior guidance, and endless patience.

Your product does not necessarily use all the software components referred to below. Copyrights and licenses The following components are subject to the BSD licenses: ? curl-7.21.0: MIT/BSD license http://curl.haxx.se/legal/licmix.html License Mixing with apps, libcurl and Third Party Libraries =========================================================== libcurl can be built to use a fair amount of various third party libraries, libraries that are written and provided by other parties that are distributed using their own licenses. Even libcurl itself contains code that may cause problems to some. This document attempts to describe what licenses libcurl and the other libraries use and what possible dilemmas linking and mixing them all can lead to for end users. I am not a lawyer and this is not legal advice! One common dilemma is that GPL[1]-licensed code is not allowed to be linked with code licensed under the Original BSD license (with the announcement clause). You may still build your own copies that use them all, but distributing them as binaries would be to violate the GPL license - unless you accompany your license with an exception[2]. This particular problem was addressed when the Modified BSD license was created, which does not have the announcement clause that collides with GPL. libcurl http://curl.haxx.se/docs/copyright.html Uses an MIT (or Modified BSD)-style license that is as liberal as possible.
