NEC America has introduced a virtual-desktop computing package designed to support demanding PC-quality graphics on thin client desktops.

The NEC Virtual PC Center (VPCC) brings together a desktop thin client with a high-powered graphics card, a dedicated virtual PC server, a management server, and integrated third-party virtualization software. An enterprise can shift PC computing into the data center for centralized management and security, while preserving the rich graphics user interface for multimedia, and cutting desktop electrical use by up to 60%, according to NEC.

Typical thin-client solutions decompress audio and video on the back-end server, then transport the uncompressed streams over the LAN, says Ken Hertzler, director of the server platform group for NEC. The result: heavy LAN traffic and poor graphics performance on the desktop.

NEC’s solution is designed to shift the multimedia decompression to the desktop, via a dedicated high-performance graphics card. At the same time, it uses pre-installed desktop virtualization client and server software from VMware to create and manage Windows desktop on the virtualization server.

Desktop virtualization is the most recent of the long-running attempts by enterprise IT groups to more easily and less expensively run and support hundreds or thousands of PC desktops. It’s drawing software infrastructure vendors like VMware, as well as start-ups such as Kidaro, which are building desktop virtualization on top of those infrastructures.

Viewing NEC’s Virtual PC Center from the user’s perspective, you replace a Windows PC with the NEC US100, a small desktop box that can come with or without display, keyboard and mouse. The palm-sized box (about 6 by 4 by 1.3 inches) sits on the desk or mounts behind a flat-panel display.

The US100 is based on hardware and software from Wyse Technology, including the recently revamped Wyse ThinOS, a fast, 2MB Linux-based software image with Wyse’s multimedia acceleration code, and built-in support for Microsoft Terminal Server and Remote Data Protocol (RDP), Citrix Presentation Server and ICA protocol, and the VMware Virtual Desktop Infrastructure.

But NEC replaced the standard CPU with the NetClient processor from ServerEngines and worked with the chip maker to add a dedicated graphics card to decompress streaming audio-video content. As a result, users see graphics performance that’s comparable to a PC, according to NEC’s Hertzler.
