    The Do’s and Don’ts of Server Virtualization Back to basics tips for Australian IT professionals Server Virtualization Reminders: Basic Do’s and Don’ts Virtualization is a well-established in today’s IT environments, but it still remains a top priority among data center managers and admins. Therefore, Contents our experts have compiled an essential guide that highlights Hosted vs. bare- some of the key elements of an effective virtualization mental hypervisor strategy from choosing the right hypervisor technology to types improving VM performance to keep top of mind. Top 10 hypervisors technologies Understanding hosted and bare-metal virtualization 4 mistakes that kill VM hypervisor types performance By: Eric Siebert Additional Resources When choosing a virtualization hypervisor, you have to consider both hypervisor types. A virtualization hypervisor comes in one of two forms: a bare-metal hypervisor, also known as Type 1; or a hosted hypervisor, also known as Type 2. There are important differences between a hosted and bare-metal virtualization hypervisor, and each has pretty specific use cases. Bare-metal virtualization hypervisors A bare-metal virtualization hypervisor does not require admins to install a server operating system first. Bare-metal virtualization means the hypervisor has direct access to hardware resources, which results in better performance, scalability and stability. One disadvantage of a bare-metal virtualization hypervisor, however, is that hardware support is typically more limited, because the hypervisor usually has limited device drivers built into it. Bare-metal virtualization is well suited for enterprise data centers, because it usually comes with advanced features for resource management, high availability and security.

    Parallels® Server for Mac Customer Success Story Business Challenge The Oregon City School District is dedicated to providing its more than 8,300 students within its 16-building K-12 school system with an actively engaging education focused on each student’s individual learning goals. To provide this progressive approach, district officials work diligently through partnerships with the community at every level to secure financial resources and educational opportunities for its schools and students. With so much emphasis on providing an individualized education that infuses technology into curriculum, the Oregon City School District found itself with a legacy server and storage infrastructure in desperate need of an overhaul.

  • Parallels Desktop® for Upgrading to Windows 7
    Parallels Desktop® for Upgrading to Windows 7 Quick Start Guide & End User License Agreement The Simple, Safe and Successful Way to Upgrade There are two ways you can use Parallels Desktop® for Upgrading to Windows 7. You can either upgrade an existing Windows XP or Vista PC, or you can purchase a new PC that has Windows 7 on it and then move your programs, files and settings to that PC. Before we look at how Parallels Desktop® for Upgrading to Windows 7 works for these scenarios, we need to spend a moment on housekeeping. Before You Begin Back up your data It is a common and good practice to keep a back up of your system or at least the files you use most. There are various backup options such as software programs that make backing up a PC simple, or affordable external hard drives that can serve as a suitable backup solution as well. You can even back up your files by simply burning them to a DVD. Especially when upgrading an operating system, regardless of which scenario you follow, we strongly recommend that you back up your files before beginning. For customers who don’t currently have a backup solution, Parallels Desktop® for Upgrading to Windows 7 comes with a free 90-day trial subscription to Acronis® Online BackUp for data backup. Handling your Anti-virus and other programs Temporarily turn off your Anti-virus programs and make sure all other open programs are closed. Just remember to turn Anti- virus protection on again when you are done to stay protected! Plug in your PC(s) Especially if you have years of programs and files stored on your computer, it will take time to move everything to Windows 7.

  • Portable Desktop Applications Based on P2P Transportation and Virtualization
    Portable Desktop Applications Based on P2P Transportation and Virtualization Youhui Zhang, Xiaoling Wang, and Liang Hong – Tsinghua University, Beijing, China ABSTRACT Play-on-demand is usually regarded as a feasible access mode for web content (including streaming video, web pages and so on), web services and some Software-As-A-Service (SaaS) applications, but not for common desktop applications. This paper presents such a solution for Windows desktop-applications based on lightweight virtualization and network transportation technologies which allows a user to run her personalized software on any compatible computer across the Internet even though they do not exist on local disks of the host. In our approach, the user’s data and their configurations are stored on a portable USB device. At run time, the desktop applications are downloaded from the Internet and run in a lightweight virtualization environment in which some resource-accessing APIs, such as registry, files/ directories, environment variables, and the like, are intercepted and redirected to the portable device or network as needed. Because applications are ‘‘played’’ without installation, like streaming media, they can be called ‘‘streaming software.’’ Moreover, to protect software vendors’ rights, access control technologies are used to block any illegal access. In the current imple- mentation, P2P transportation is used as the transport method. However, our design actually does not rely on P2P, and another data delivery mechanism, like a dedicated file server, could be employed instead to make the system more predictable. This paper describes the design and technical details for this system, presents a demo application and evaluates it performance.
