Selecting a VDI environment is a daunting process. As I begin to evaluate technologies for VDI design and implementation for an upcoming project, the first step is often to identify the requirements from the end-user perspective.
Administrators frequently get wrapped up in the server side of a technology that the experience end of the solution may be overlooked. Two specific pieces of functionality such as screen resolution and dual monitor support can be incredibly important to the endpoint experience, and may make an implementation fail if it does not meet the requirements of all applications involved. By comparison, other topics such as USB device support, printing and sound are more of a policy decision rather than a device selection process decision.
We strategically arrive at determining device capabilities to match the requirements. At that point, we can then ‘back into’ various backend VDI solutions. Take for example the Sun Ray 2FS Virtual Display Client, which offers two DVI-I (digital video interface) ports that can provide a resolution with one monitor at 1920 x 1200 resolution, or two monitors at 3840 x 1200. Among VDI devices the standard offering is a 1600 x 1200 resolution which will satisfy most resolution situations, however. The dual DVI-I monitor may seem like overkill for a VDI-based thin client, but for many systems that perform archival by scanning documents, the high resolution and dual monitor functionality may be a requirement. Just ask any accounts payable clerk.
Some of this functionality may be circumvented by the use of existing devices, specifically VDI solutions that allow a Windows or other operating system PC to connect to the VDI broker. In this regard, if there are a very limited number of systems with requirements that may not be accommodated with standard endpoint devices, the typical PC can be used to provide the VDI connection from a full install PC. While not ideal, it is a decent stop-gap measure and a way to use of existing equipment.
