R10.30.08 Solution Brief Desktop Virtualization Configurations NComputing desktop virtualization solutions solve the challenges of deploying dedicated PCs for businesses and organizations worldwide. By accessing the world’s largest untapped computing cloud – the unused compute cycles of desktop PCs – NComputing brings computing access to places it has never been before and dramatically lowers costs for places where computing already exists. The solutions’ key benefits of affordability, compatibility, efficiency and simplicity have helped NComputing deploy over one million seats in just the last two years. Low Cost Access Devices Instead of using desktop PCs or traditional thin clients to deliver computing access to users, the NComputing solution uses low-cost, highly optimized and efficient access devices that tap into the unused power of existing PCs and servers. Many solutions in the market today that claim to do desktop virtualization still rely on a full desktop PC as the end-user interface. While these approaches address some of the challenges of PC management and security, they increase the upfront costs and add complexity. Other solutions in the market use traditional thin clients which in most cases are effectively scaled-down PCs with the familiar PC components including x86 motherboards, processors, memory, local storage, and operating systems. NComputing access devices are truly different and are built with just a single, highly-efficient and integrated chip. The result is a cost per access device of as little as $70, an extremely small size, and energy consumption of as little as one watt per user. Basic Desktop Virtualization with vSpace™ NComputing devices connect via the User eXtension Protocol (UXP) to virtual workspaces hosted on PCs and servers in a variety of ways. The most popular way is to run the NComputing vSpace virtualization software directly in the main operating system of a shared PC (i.e. Windows Server 2003 or Linux). vSpace then creates multiple virtual workspaces that each connects to an individual X-series (direct connection up to 10 m) or L-series (Ethernet connection for any distance) access device. In this efficient configuration up to 30 users can share a standard PC or entry-level server.
