![]() For example, when I went to change the maximum bandwidth setting, I was informed how it would affect the connection ( Figure 6). One of the nice features with these settings is that an explanation is given in the setting's Help section. To test the PCoIP settings, I disabled clipboard redirection using gpedit ( Figure 5) and then logged into the virtual desktop and found that clipboard redirection was, in fact, disabled. I entered gpedit.msc in the start box of my virtual desktop and navigated to Local Computer Policy/Computer Configuration/Administrative Templates/PCoIP Session Variables/Overridable Administrator Defaults ( Figure 4). If you use Windows 10, you'll be able to install the ADMX file from gpedit directly by entering gpedit.msc in the start box, then navigating to Computer Configuration, right-clicking Administrative Template, selecting Add/Remove Template, clicking Add, and finally selecting the pcoIp.admx file ( Figure 3). The pcoip.admx file.Īfter extracting the pcoip.admx file from the archive and copying it to my Windows 7 virtual desktop, I copied the contents of the ADMX folder to the local PolicyDefinitions folder on my Windows 7 virtual desktop at C:\Windows\PolicyDefinitions. zip file includes pcoip.admx file, as well as other ADMX files ( Figure 2). The GPO bundle will be downloaded as the VMware-Horizon-Extras-Bundle-5.0.0-xxx. The policies for PCoIP are stored in an ADMXtemplate file ( pcoip.admx) available in VMware-Horizon-Extras-Bundle-x.x.x-yyyyyyy.zip, which can be downloaded from under the VMware Horizon 7 download section by selecting the View GPO Bundle ( Figure 1). This article will show you how to adjust them on a per-virtual-desktop basis, but much of the information can be used to adjust a group of desktops. PCoIP settings can be adjusted on an individual virtual desktop, or on a group of virtual desktops by modifying an Active Directory Group Policy or by using Horizon 7 policies, which are set from the Horizon Administrator. That said, in some (albeit rare) cases, modifying these settings can radically improve an end user's VDI experience. ![]() Although I did find information on how to adjust these settings in older documentation, this information was outdated and didn't match up with what I was seeing on my installation.īefore I dive into the article and explain how I was able to modify PColP settings, however, you should be aware that in the vast majority of cases, PCoIP settings should not be modified- you can hurt, rather than help, the performance of your VDI deployment. ![]() I checked the official VMware and Teradici (the creators of PCoIP) documentation for guidance on how to do this, but didn't find much information. I recently wanted to modify the PCoIP settings on my installation of Horizon 7.7 that was using a Windows 7 virtual desktop. To show how build-to-lossless works, imagine that you're scrolling down through a Web page on your virtual desktop: at first you'll have low resolution or lossy graphics, and if you stay on the page the graphics will soon achieve their native resolution or become lossless, but if you move on from the page, unneeded graphic information won't be transferred over the network. In highly simplified terms, it starts with a low-resolution version of what's being displayed and then the display will progressively transition to a higher resolution over time. "Build-to-lossless" is a clever way that PCoIP can increase an end user's experience with his virtual desktop and reduce network traffic. Also, as PCoIP transfers information such as video, audio, and USB, and other interactions between a VDI client and a virtual machine, PCoIP allows you to dictate the amount of bandwidth these interactions can consume. For example, because you may want to have PCoIP manually cap the amount of data that's transferred over the network, PCoIP allows you to put a maximum on the amount of network traffic that a VDI session can consume. PCoIP constantly monitors its network connections and will adjust how much data is being transferred from the virtual desktop to the VDI client as needed. ![]() In this article, I'll first give a brief overview of PColP and then discuss some its settings that can be modified and how I modified them. PCoIP allows you to adjust these settings in order to modify the experience that an end user has with his virtual desktop. Some of the techniques that PCoIP uses to decrease the amount of network traffic from the virtual desktop to the VDI client include compressing data, capping the amount of bandwidth each PCoIP session can consume, prioritizing certain streams of data and building a graphic display to lossless. PC over IP (PCoIP) is one of the protocols that can be used by Horizon, VMware's Virtual Desktop Infrastructure (VDI) solution, which allows the information from a virtual desktop to be efficiently transferred and displayed to a VDI client.
