Introduction

1.1Introduction

Desktop virtualization provides a new perspective to reconsider the design and implementation of an IT infrastructure. In a desktop virtualization infrastructure, a station is no longer a cumbersome desktop, but simply an endpoint device for users to access delivery services from the server(s).

With the introduction of the desktop virtualization technologies, you can considerably benefit from:

•On-demand applications/desktops

•Centralized management of work environments

•Drastically reduced endpoint software/hardware issues

•Simplified system maintenance and Improved system security

•More scalability with low-cost endpoint devices

1.2Features

The key features of Atrust t60/t62 thin clients are:

•Support for a wide range of desktop virtualization solutions from industry-leading companies:

ŹŹMicrosoft® Remote Desktop

ŹŹCitrix® XenApp™, XenDesktop®, and VDI-in-a-Box™

ŹŹVMware® View™ and Horizon View™

•Support for high-definition technologies:

ŹŹMicrosoft® RemoteFX®

ŹŹCitrix® HDX™

ŹŹVMware® View™ PCoIP®

•Simple click-access to various applications/desktops

•Built-in Atrust Client Setup as the local client management console
