  • Serverless Network File Systems
    Serverless Network File Systems Thomas E. Anderson, Michael D. Dahlin, Jeanna M. Neefe, David A. Patterson, Drew S. Roselli, and Randolph Y. Wang Computer Science Division University of California at Berkeley Abstract In this paper, we propose a new paradigm for network file system design, serverless network file systems. While traditional network file systems rely on a central server machine, a serverless system utilizes workstations cooperating as peers to provide all file system services. Any machine in the system can store, cache, or control any block of data. Our approach uses this location independence, in combination with fast local area networks, to provide better performance and scalability than traditional file systems. Further, because any machine in the system can assume the responsibilities of a failed component, our serverless design also provides high availability via redundant data storage. To demonstrate our approach, we have implemented a prototype serverless network file system called xFS. Preliminary performance measurements suggest that our architecture achieves its goal of scalability. For instance, in a 32-node xFS system with 32 active clients, each client receives nearly as much read or write throughput as it would see if it were the only active client. 1. Introduction A serverless network file system distributes storage, cache, and control over cooperating workstations. This approach contrasts with traditional file systems such as Netware [Majo94], NFS [Sand85], Andrew [Howa88], and Sprite [Nels88] where a central server machine stores all data and satisfies all client cache misses. Such a central server is both a performance and reliability bottleneck. A serverless system, on the other hand, distributes control processing and data storage to achieve scalable high performance, migrates the responsibilities of failed components to the remaining machines to provide high availability, and scales gracefully to simplify system management.

  • Chapter 1. Origins of Mac OS X
    1 Chapter 1. Origins of Mac OS X "Most ideas come from previous ideas." Alan Curtis Kay The Mac OS X operating system represents a rather successful coming together of paradigms, ideologies, and technologies that have often resisted each other in the past. A good example is the cordial relationship that exists between the command-line and graphical interfaces in Mac OS X. The system is a result of the trials and tribulations of Apple and NeXT, as well as their user and developer communities. Mac OS X exemplifies how a capable system can result from the direct or indirect efforts of corporations, academic and research communities, the Open Source and Free Software movements, and, of course, individuals. Apple has been around since 1976, and many accounts of its history have been told. If the story of Apple as a company is fascinating, so is the technical history of Apple's operating systems. In this chapter,[1] we will trace the history of Mac OS X, discussing several technologies whose confluence eventually led to the modern-day Apple operating system. [1] This book's accompanying web site (www.osxbook.com) provides a more detailed technical history of all of Apple's operating systems. 1 2 2 1 1.1. Apple's Quest for the[2] Operating System [2] Whereas the word "the" is used here to designate prominence and desirability, it is an interesting coincidence that "THE" was the name of a multiprogramming system described by Edsger W. Dijkstra in a 1968 paper. It was March 1988. The Macintosh had been around for four years.

  • Tips and Tricks for OS X Lion 10.7 Introduction
    Mac Information Tips and Tricks for OS X Lion 10.7 Introduction: Lion was introduced in the middle of 2011 and came with lots of changes such as Mission Control and Launchpad. However here are a list of smaller changes, ones which you may never have noticed... 1/ Put your contact info on the login screen Lion now allows you to place a personal message with your contact information on the login screen which may be useful if your laptop is lost or stolen. To enable the feature, go to your Security & Privacy in System Preferences, click on the General tab and click on the padlock in the lower left corner to unlock your settings. Then tick the box labeled "Show a message when the screen is locked”. Click on the “Set Lock Message...” button and type in the message which you would like to appear on your login screen. 2/ Always Display Scroll Bars Under Lion, scroll bars on the side have been reduced in importance. In the past, users dragged the scroll bar or used the arrows under the scroll bar. to navigate a document or window. With the advent of trackpads these scroll bars are now just an indication of your position on a page. Under Lion the scroll bars fade out after a few seconds unless you change a setting. In System Preferences, click on the General section, and then choose the “Always” option. 3/ Turn Off Restore Windows Lion also brought in a “restore windows” feature which means that windows which are open when you quit an app re-open the next time you choose that app.
