Technology Overview

Zero Architecture:

SUNDE Zero Client is a compact, purpose-built desktop virtualization hardware endpoint that connects the end user’s display, input devices and other USB peripherals to the system running on the server in the data center. SUNDE device is referred to as Zero Client because in contrast to thin client and PC endpoints, it contains no CPU, no local storage, and no operating system. As a result, it requires no endpoint management software, no patch management, and no local operating system licensing fees or updates. The device consumes very little power and is tamper-resistant and completely incapable of storing any data locally, providing a more secure endpoint.

By eliminating all configuration, computation, and management of the endpoint, the Zero Client architecture allows for 100% centralization, computation and management in the data center. In a Zero Client System, all services – including Desktops management, Device Discovery, Authentication, Session Brokering, Change of Control, Windows driver support, storage IOPs, and more – are handled in the backend data center. Hence, a very simple endpoint, i.e. a Zero Client, is sufficient to provide users with access and interaction to their virtual desktop.
The Zero Client architecture uniquely eliminates the high tax associated with other endpoint solutions such as PCs, thin clients, and other clients:

• Eliminates the management tax: No processor, no operating system, and no local drivers means there is nothing for IT to configure, manage, or update. An untrained user can plug one in and be productive immediately.
• Eliminates the security tax: No ability to execute arbitrary code means inherent protection against malware, viruses, keystroke loggers, and elimination of IT time trying to secure the endpoint environment.
  
• Eliminates the 3-year replacement cycle tax: Pure hardwired logic for the device’s subsystems, and no moving parts, means the lowest complexity and longest-lasting endpoint solution.
• Eliminates the power tax: Only 5 watts including keyboard and mou
  se, 95% less than PC deployments and substantially less than thin clients. Including server power, power savings are over 80% out of the box.

Peripheral support

SUNDE firmware that resides in the devices enables the deployment of server-based applications and transparent support for a variety of USB desktop peripherals that may be used for input or output of data. This functionality is transparent to the application and the Terminal Services session or the virtual machines on the server.
Supported local devices include wired or wireless keyboards, mice, various printers & scanners, memory mass storages, webcams, U keys and USB to parallel/ serial converters, etc

SUNDE Windows Audio Input and Output Support software enables 12 bit stereo audio input / output to be achieved via 3.5mm stereo jacks at the terminal. Supported audio formats range from the familiar Windows audio cues to video files to internet accessed audio from browsers.

Multimedia Support

SUNDE VDI system delivers an extremely high performance virtual desktop for users including rich multi-media, full screen 1080P streaming video and Flash, dynamic graphics, and seamless responsiveness on 5 watts power consumption Diana zero clients connecting via SUNDE's patented protocol to the vPoint software mounted on the virtual server platform, without relying on any 3rd party software or GPU configuration.
