I have recently found there is an issue with the latest version of the Teradici PCoIP Zero Client firmware 3.5.0 and View 5.0 during a deployment. This affected all users connecting from zero clients both the Wyse P20 and the Dell FX100 (in theory also any other PCoIP zero clients), causing a black screen when logging onto a View desktop followed by being returned to the View Client login screen.

Teradici have released a PCoIP server offload card called the APEX 2800. This server based PCI express card offloads the PCoIP image encoding tasks which thus reduces server CPU utilization.
This can create a headroom for existing virtual desktops, increase the number of desktops per server for VMware View deployments and may also improve the user experience.
More details can be found on the Teradici website http://www.teradici.com/pcoip/pcoip-products/teradici-apex-2800.php
Teradici APEX 2800 Server Offload Card Requirements:
- PCI Express x8 compatible card slot
- VMware ESXi 4.1 U1/U2 or 5.0
- VMware View 4.6 or 5.0
- PCoIP Zero Client (3.4.x or later) or VMware View client (4.6 or later)

Adobe Flash content can be redirected to the user device for local rendering in many more cases than before, resulting in even higher server scalability and a great user experience. Flash Redirection now supports WAN-connected users. Good results with video playback have been observed, even at high latency.
