Copy on Write Based File Systems Performance Analysis and Implementation
Copy On Write Based File Systems Performance Analysis And Implementation Sakis Kasampalis Kongens Lyngby 2010 IMM-MSC-2010-63 Technical University of Denmark Department Of Informatics Building 321, DK-2800 Kongens Lyngby, Denmark Phone +45 45253351, Fax +45 45882673 [email protected] www.imm.dtu.dk Abstract In this work I am focusing on Copy On Write based file systems. Copy On Write is used on modern file systems for providing (1) metadata and data consistency using transactional semantics, (2) cheap and instant backups using snapshots and clones. This thesis is divided into two main parts. The first part focuses on the design and performance of Copy On Write based file systems. Recent efforts aiming at creating a Copy On Write based file system are ZFS, Btrfs, ext3cow, Hammer, and LLFS. My work focuses only on ZFS and Btrfs, since they support the most advanced features. The main goals of ZFS and Btrfs are to offer a scalable, fault tolerant, and easy to administrate file system. I evaluate the performance and scalability of ZFS and Btrfs. The evaluation includes studying their design and testing their performance and scalability against a set of recommended file system benchmarks. Most computers are already based on multi-core and multiple processor architec- tures. Because of that, the need for using concurrent programming models has increased. Transactions can be very helpful for supporting concurrent program- ming models, which ensure that system updates are consistent. Unfortunately, the majority of operating systems and file systems either do not support trans- actions at all, or they simply do not expose them to the users. -

Microsoft Windows 10 Update Hello, Microsoft Has Begun
Subject Line: Microsoft Windows 10 Update Hello, Microsoft has begun pushing a warning message to Windows 10 computers that a critical security update must be performed. Several clients have informed us that they are seeing the warning message. It will appear as a generic blue screen after your computer has been powered up, and it states that after April 10, 2018 Microsoft will no longer support your version of Windows 10 until the critical security update has been performed. Please note if your UAN computer has not been recently connected to the internet, you would not have received this message. UAN has confirmed that the warning message is a genuine message from Microsoft, and UAN strongly encourages all clients to perform this critical security update as soon as possible. Please note: ‐ This update is a Microsoft requirement and UAN cannot stop or delay its roll out. To perform the critical security updated select the ‘Download update’ button located within the warning message. ‐ This update is very large, for those clients that have metered internet usage at their home may want to perform the update at a different location with unmetered high speed internet, perhaps at another family member’s home. ‐ Several UAN staff members have performed the critical security update on their home computers, and the process took more than an hour to complete. To check that your computer has been updated or to force the update at a time that is convenient to you, go to the windows Start button and click on Settings (the icon that looks like a gear above the Start button) > Update and Security > Windows Update > Check for Updates and then follow the instructions on the screen. -
How to Set up Cortana (Or Remove Her) in Windows 10
How to set up Cortana (or remove her) in Windows 10 Cortana, the personal digital assistant feature in Windows 10, will help you complete tasks, make it to your appointments on time, send messages and emails on your behalf, research the web and even launch applications. Orignally released with the Windows Phone (and named after the AI character from Microsoft's Halo franchise, looks to be a key element in the Windows 10 operating system. To begin the set up process, click or tap the microphone icon in the search bar and say "Hey Cortana" (if listening is enabled), followed by your question or search term. When properly set up Cortana is a powerful digital assistant. Start by clicking into the Cortana search box, and waiting for the results pane to appear. In the top- left corner of this, click the “hamburger” menu and then open Notebook. This tool allows you to determine what information Cortana can gather about you, and the more data she has, the more she can do. Cortana will have already asked you to input your name, but you can change this and more by opening About Me. Here, set the name you want her to use. Under Settings you can enable tracking info by switching on Find flights and more, which analyses your emails for such details. The Settings screen also enables you to toggle whether Cortana responds to “Hey, Cortana” which is very similar to Android’s “OK, Google“–the system will constantly be on the look-out for you saying this phrase, and will open Cortana when it is detected. -

The 12 Essential Tasks of Active Directory Domain Services
WHITE PAPER ACTIVE DIRECTORY DOMAIN SERVICES The 12 Essential Tasks of Active Directory Domain Services Using the right tools and processes helps reduce administrative overhead and ensures directory service is always available By Nelson Ruest and Danielle Ruest Sponsored by WHITE PAPER ACTIVE DIRECTORY DOMAIN SERVICES ABSTRACT Active Directory Domain Services (AD DS) administration and management includes Sponsored by 12 major tasks. These tasks cover a wide breadth of business needs and are not all performed solely by AD DS administrators. In fact, administrators can and should delegate several tasks to other members of their technical community, technicians, help desk personnel, even users such as team managers and administrative assistants. While delegation is a way to reduce the amount of work administrators have to do when managing AD DS infrastructures, it really only addresses one or two of the 12 tasks, for example, user and group administration as well as end point device administration. The other ten tasks can be staggering in nature—security, networked service administration, OU-Specific Management, Group Policy Object management and many more—and because of this can take up inordinate amounts of time. You can rely on Microsoft’s built-in tools to reduce some of this workload, but are the native tools enough? Perhaps it’s time to reduce AD DS administration overhead by automating most tasks and tightening internal security. Address this by first, determining what the twelve essential labors of Active Directory are and then, see how you can reduce AD DS workloads through the implementation of proper management and administration tools. -
