Dell Desktop Virtualization Solutions (DVS) Simplified Desktop as a Service (DaaS) delivers full-featured virtual desktops – powered by Desktone – from Dell’s state-of-the-art data centers. This cloud-based solution simplifies your desktop virtualization deployment, reduces upfront investment and offers you the option of low monthly payments, gives you the flexibility to rapidly scale from a few seats to thousands, and enables access from a range of end point devices including PCs, mobile devices and Dell Wyse thin clients and zero clients.
Starting in October, DVS Simplified DaaS will be available with PCoIP® protocol for connecting to virtual desktops from VMware View Clients to meet the demands of users with specific multimedia needs. Remote users can now have an exceptional experience with high definition (HD) multimedia including high resolution, full frame rate 3D graphics and HD audio, multiple large displays, and full USB peripheral connectivity.
With this addition, DVS Simplified DaaS now offers two protocol options – PCoIP and Microsoft’s Remote Desktop Protocol (RDP). But which protocol is right for you? The answer depends on what user scenarios you are trying to solve.
DVS Simplified DaaS supports a number of use cases including office-based task workers, power users, remote and field workers, and users accessing their desktops from wireless or cellular networks from a range of devices including smartphones and tablets. Both RDP and PCoIP support most typical task worker use cases. However, PCoIP has some performance benefits for HD multimedia and video, remote workers who are located far from the data center and are thus subject to high latency, and remote workers accessing their desktops from low bandwidth networks.
So what is PCoIP and how does it work?
PCoIP is a display compression technology, developed by Teradici®, tuned for desktop delivery over a WAN. It compresses, encrypts and encodes the entire computing experience at the data center and transmits it “pixels only” across any standard IP network. There are three essential features that contribute to its advanced performance:
Host Rendering – The display is rendered on the virtual desktop in the cloud and the captured image is transmitted as encrypted pixels to the client, thereby enabling secure, stateless, decode-only devices – such as Dell Wyse thin clients – to display the desktop. Users no longer need to install and manage multiple components for playing media locally; PCoIP works with all browsers and applications and can support Flash, Silverlight, MPEG, and even emerging delivery formats such as HTML5.
Multi-Codec Display Processing – The display image is continuously analyzed and decomposed into simpler elements – graphics, text, icons, photographs, video, etc. – each element is compressed with the right codec. This enables it to overcome network quality issues such as jitter and dropped packets by depending on the codecs to determine whether the lost data was “useful” - in many cases, it can recover without retransmission.
Dynamic Adaptation to Network Conditions – It leverages UDP which enables it to overcome the latency issues normally encountered in delivering desktops over long distances and to deliver the best user experience for the network bandwidth that’s available. Adaptive encoders automatically adjust image quality on congested networks within the limits you set then resume maximum image quality when more bandwidth is available – building up to a lossless, pixel-perfect image as needed.
Whether you are a small business, a large enterprise or a public sector entity, DVS Simplified DaaS gives you the flexibility to support a number of business needs. The key in enabling your end users to be more productive is to assess their needs and select the right configuration based on their different usage scenarios. The addition of PCoIP to DVS Simplified DaaS gives you an additional option to help your end users have the richest experience under all circumstances.
