Important: Many of the optimizations available to the other codecs have not yet been developed for the Blast Codec, including the ability to set custom image qualities. Three Blast Extreme components are built into the Horizon Agent, which administrators install in virtual desktops and Microsoft RDSH servers: Log files related to Blast Extreme can be found in the following locations: To collect logs on a Mac, you can use the Horizon Collector for Mac Fling (which like all VMware flings, is not officially supported). Explore the latest VMware tools designed to get your end-user computing environment running smoothly and efficiently. For this reason, HEVC in Blast Extreme requires that the ESXi hosts supporting the virtual desktops and RDSH servers have NVIDIA Tesla or newer GPUs to offload its encoding. Do not attempt to support high-quality use cases over a WAN or poorly functioning network. Computer Configuration -> Policies -> Administrative Templates -> VMware Blast -> Max Frame Rate. Ability to meet performance requirements for visually demanding applications when used with NVIDIA Tesla GPUbased hardware acceleration in the host. Use Adobe Flash redirection if extensive use of Adobe Flash must be supported. The following table details the requirements for each codec. This is also due to a limitation of desktop-class video drivers. If the file does not exist, it will create it with the blast settings already enabled. 1. Note: Requires Horizon Agent 7.10 and Horizon Client 5.2 or later. Deselect all other codecs and codec options. VMware Blast Extreme uses the H.264 video encoding standard which any modern mobile device can handle in its GPU, rather than CPU. Mark Ewert has been working in IT for over 25 years, with nearly two decades hands-on experience with VMware technologies. The following registry settings have been determined through extensive testing to provide the biggest impact on system resources and user experience. Use HTML5 multimedia redirection if resource-intensive web-browser-based content such as YouTube or eLearning streaming video must be supported. Blast Extreme can also use the certificate thumbprint of the Blast Secure Gateway or virtual desktop.
Best Practices for Published Applications and Desktops in VMware Applications and use-cases that require higher quality typically have demanding graphical requirements that can only be supported by hardware GPUs. Blast Extreme must be on TCP 443 only (as described previously for port sharing). . H.264 will provide support for full-motion graphics, whereas the encoder switch will ensure that the most efficient codec is dynamically used for each screen based on screen content. For external connections: Unified Access Gateway 2.9 or later. Be certain to test key applications and multimedia content before widespread deployment. Instructions for configuring all of the Blast Extreme codec options are provided in the next chapter, How to Configure Blast Extreme. You can increase the rate, up to 60 FPS, by using the Windows Registry setting.

[VVCSessionManager] BlastSocketDataSockActivatedCb: Data Connection:UDP, [VVCSessionManager] BlastSocketDataSockActivatedCb: Data Connection:TCP. After a fair amount of research, we came to the conclusion that it is best to run cameras on Thin Clients, as opposed to Zero Clients. HTML5 multimedia redirection transfers this screen content to the client as HTML5 code instead of far less efficient display protocol traffic. Added recommendations for supporting work-at-home and home-office-to-cloud use cases. The following diagram shows the ports used for an internal connection, and the list that follows describes the order in which the connections are made. Continuing the theme of useful registry key settings you can bake into your image or manually configure for some quick testing, below is a list of corresponding Blast Extreme registry settings to the Horizon 7. Begin your journey leveraging cloud-based services for desktop environments. Testing has shown this reduces the bandwidth required to support such content by up to 80 percent. The encoder switch ensures that the most efficient codec is dynamically used based on screen content. In addition to leveraging all of the optimizations described in the preceding section for still images, 3D design, and font quality, try the following suggestions: VMware Horizon and Blast Extreme support not just virtual desktops, but physical ones too. Use of a solid color with no image or pattern is recommended. It is possible to configure the Blast External URL on the Unified Access Gateway appliance to use port sharing on TCP port 443 so that no additional ports need be opened on the front-end firewall. 1 In VMware Horizon, when using PCoIP Secure Gateway on the Connection Server or Security Server. The Blast Codec should be evaluated for use whenever network bandwidth or display protocol CPU utilization is a primary concern. NVIDIA Encoded H.264(H.264 Offloaded to GPU). EUC Solutions Exchange on VMware CODE is the best place to find and share snippets. You are about to be redirected to the central VMware login page.
VMware Horizon 2206 release enhances security, end-user experience, and Typical Microsoft Office use, for example, results in a very low display protocol frame rate. 2. Here's a screen shot of the codec settings from the Horizon client: If you uncheck the option, "Allow H.264 decoding," you'll fall back to JPG/PNG and Performance Tracker will report, "adaptive", as the encoder. VMware recommends using VMware Dynamic Environment Manager (formerly known as User Environment Manager). However, it does increase client CPU utilization by up to 200 percent for the duration of the redirection (from an average of 8 to 24 percent on a sample test system). Blast Extreme uses the latest security algorithms, including SHA-256. If desired, the traffic between the Unified Access Gateway and Horizon Agent can be configured to use a separate port (TCP 9427). Note, however, that the encoder switch cannot currently be used with High Efficiency Video Coding (HEVC) or when H.264 and H.264 with High Color Accuracy encoding is offloaded to an NVIDIA GPU. We also frequently discover that the underlying ESXi hosts are overutilized and are exhibiting clear indicators of problems impacting user experience such as high CPU Ready times. Audio is also enabled, but is not currently being used. NVIDIA H.264 with HighColorAccuracy setting, which limits only the display traffic without negatively impacting audio, file transfer, or other supporting services. This will force H.264 to start at higher quality and prevent it from expending bandwidth to send initial low-quality screens. If this functionality is used, configuration settings are created within each users profile in the following registry key: HKEY_CURRENT_USER\SOFTWARE\Vmware, Inc.\Vmware Blast\Config. The following updates were made to this guide. End-users access to their personalized virtual desktops or remote applications from company laptops, their home PCs, thin client devices, Macs, tablets, or smartphones.
