HEVC provides up to 50 percent better compression with the same quality as H.264 and can also provide higher quality at similar compression ratios as H.264. Yes: Deselect all codecs and codec options (uncheck: H.264, Allow High Color Accuracy, and Allow High Efficiency Video Coding). If the testing in your environment is not successful, use JPG/PNG. VMware Blast performance and end-user experience acceleration Blast is now the new default. The Horizon Clients can use either IP version 4 or 6. Question: 1. Most Macs, laptops, and Windows PCs manufactured in 2013 or later. Start with these recommendations before moving on to more specialized settings. 3 enabled server to client only. To find out which Blast Extreme settings are available for a specific client platform, see the Horizon Client user guide for that platform, available from the VMware Horizon Client Documentation page. They are designed to have something for people of every experience level. HDR also requires Horizon 8 (210) or later with Horizon Agent build 2106-8.3.0-18287218 or later and Horizon Client build 2106-8.3.0-18287501 or later. The Connection Server returns the connection information for the virtual desktop or RDSH server that provides remote applications (on TCP port 443). If users experience any of these issues, HCA can be enabled to improve quality while preserving H.264s multimedia efficiency. (the lowest currently supported setting). Although this strategy makes for reliable delivery, the process adds overhead. However, some use cases and situations require additional tuning, especially for wide area networks (WANs). The following tuning recommendations apply to all WAN conditions. Problem is with second file, which is growing sometimes up to 15GB, then new files are created. 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. A key design principle with VMware Blast Extreme is to offload graphics processing from the CPU, which reduces the power consumption for accessing a desktop. EncoderHEVCEnabled Enables or turns off support for the HEVC codec (H.265). You are about to be redirected to the central VMware login page. Use HTML5 multimedia redirection if resource-intensive web-browser-based content such as YouTube or eLearning streaming video must be supported. Lower power consumption means longer battery life. If i look into the Settings of the vmware microphone, i can just choose between 8000 Hz and 16000 Hz (default is 8000Hz). Navigate the sophisticated world of Unified Access Gateway (UAG) for Workspace ONE and Horizon 8. The Horizon Performance Tracker is an option that can be selected during the Horizon Agent installation on the virtual desktop, physical desktop, or RDSH server. Although RAM is rarely the bottleneck, monitor RAM to ensure it is not being over utilized by applications. VNCRegionEncoder_Create: region encoder switch. NVIDIA and AMD GPUs are not able to support OpenGL due to a limitation of their video drivers. HEVC provides up to 50 percent better compression with the same quality as H.264. Get all the Tech Zone demos in one place. Blast Extreme was carefully designed to provide an excellent out-of-the-box experience, with no additional configuration required in almost all cases. High Efficiency Video Coding (HEVC) TCP port 9427 is then used from the Unified Access Gateway to the agent. For more information, see, Common Criteria Certification Report for VMware Horizon. Blast Extreme will always resort to using more bandwidth, if necessary, to prevent the session from crashing. Deselect all other codecs and codec options. The next section describes the workflow of connections made between the client and agent components. Multimedia redirection traffic uses TCP 9427. On the server side, H.264 encoding can be offloaded to NVIDIA Tesla GPUs, freeing the costly CPUs in. This connection is from the client to UDP port 8443 on the Unified Access Gateway. Limiting the resolution of employees monitors also greatly reduces Internet circuit bandwidth utilization. Various components of a display protocol can be configured to address the different types of screen content and differing network speeds that end users are likely to encounter. Flash redirection causes the client to download and execute Flash content instead of rendering it in the virtual desktop and sending it across the WAN. The goal is to configure QoS to prioritize Blast Extreme above general network traffic, but below the few applications that are even more sensitive to delay. See. If you use a Unified Access Gateway virtual appliance for connections from outside the corporate network, by default the connection uses TCP port 8443 and optionally UDP port 8443. The Blast Extreme template is named: vdm_blast.admx and can be found in the VMware-Horizon-Extras-Bundle-xxx.zip file, with xxx indicating the corresponding version of Horizon. Note: Dynamic Environment Manager also provides optimization templates for Blast Extreme. Introduced in Horizon 8 (2106) is support for High Dynamic Range (HDR) encoding to provide higher graphical quality with vastly improved color range and contrast. A codec is used to encode and decode the screen content transferred by Blast Extreme. Value: 1. More information about the admin settings is provided in the next section of this chapter. My email is nikoloz.qutidze@gmail.com The Blast Codec will continue to evolve. Most settings make the option available to be used (set to 1) or not (set to 0). It is not supported in Horizon 7. 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). Testing has revealed this reduces desktop and per-user RDSH server CPU utilization by up to 60 percent and per-user session bandwidth by up to 80 percent. If possible, implement network Quality of Service (QoS) to further help maximize the capacity of these Internet circuits and prevent competing network traffic from degrading the performance of Blast Extreme. The settings are configured in the Windows Registry of the Windows virtual and physical desktops and Microsoft RDSH servers. VNCSERVER-WIN32: ***Setting topology completed by Nvidia Display***. In this file, add the single line: RemoteDisplay.allowClientBlastCodec = TRUE. Watch conversations with VMware experts on top-of-mind issues. HEVC can also support higher quality at similar compression ratios as H.264, but again at the cost of more processing power with no bandwidth savings. The settings allow you to manage the maximum bandwidth that any one user can consume. Watch conversations with VMware experts on top-of-mind issues.

For the following conditions, VMware recommends that you use TCP rather than UDP: For all other network conditions, VMware recommends that you use UDP for the best user experience. The following registry settings have been determined through extensive testing to provide the biggest impact on system resources and user experience. Offloading the display protocol encoding is enabled by default but can also be turned off if the GPUs must be dedicated to supporting other tasks. Incorporated various recent suggestions from reviewers. Yes: Select Allow H.264 Decoding. Developed for a variety of workloads, Blast is optimized for an ideal user experience and resource consumption. Navigate to Virtual Machine > Settings (Fusion) or VM > Settings (Workstation). Although this results in a similar reduction in the network bandwidth required, it uses substantially more CPU processing power to encode and decode. The table in each section outlines the settings configured by the application template. You can configure group policy settings that control the behavior of Real-Time Audio-Video (RTAV) on your remote desktops. However, if the network also supports interactive video, Blast Extreme is often marked one-level lower with a DSCP marking of AF31. These settings will override all other Blast Extreme settings. Ability to meet performance requirements for visually demanding applications when used with NVIDIA Tesla GPUbased hardware acceleration in the host. All three howeverNVIDIA, AMD, and Intelare able to support Microsoft DirectX. Be certain to test any QoS configuration extensively to ensure not just proper performance for Blast Extreme, but that the configuration does not negatively impair other applications and services that the network must also support. VMware made the DPI setting on the client device leading and adjusts the remote desktop accordingly. Display protocols have similar performance characteristics. Optimized for the mobile cloud, VMware Blast Extreme supports a broad range of client devices, including Windows, Linux, Mac, Android, iOS, Chrome, and web (HTML Access) clients.

Note: At this point, the VMware Blast service on the agent side (Horizon Agent on the virtual desktop or RDSH server) proxies the incoming connection. :\ProgramData\VMware\VMware Blast\. Figure 1: Choosing Blast Extreme in the Horizon Client Options. HEVC will not work with ESXi CPU encoding alone. 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). When traffic must pass through a UDP-hostile network service or device such as a TCP-based SSL VPN, which re-packages UDP in TCP packets, If WAN circuits are experiencing very high latency (250 milliseconds and greater). No tuning for Network Latency: Low bandwidth / High latency Environments require additional tuning, Please see Tuning Blast Extreme for Wide Area Networks for details. Use TCP if latency is greater than 250 milliseconds. To observe this in action we can control the codec selection using the VMware Blast settings on the Horizon client. Except in unique situations, optimizing quality increases bandwidth utilization, whereas optimizations for WANs require limiting quality to function over poor network conditions. Using articles, videos, and labs, this activity path provides the fastest way to learn Workspace ONE! General settings include both Computer Configuration and User Configuration settings.

Added guidance on the benefits of HTML5 multimedia redirection. The evaluation process has been initiated. Horizon is a complete solution that delivers, manages, and protects virtual desktops, RDSH-published desktops, and applications across devices and locations. If testing reveals the Blast Codec is not yet able to fully support an application or use case, simply switch to one of the other three codecs for now. If UDP is enabled on the client, the Unified Access Gateway, and the agent (default), the client attempts to make a UDP connection to the agent via the Unified Access Gateway. It is especially good at reproducing intricate fonts and other screen content with fine details, including still images and low-motion 3D modeling used by design and engineering applications. In testing, Blast Extreme has been measured using essentially the same amount of bandwidth with both TCP and UDP. If the Horizon Performance Tracker cannot be used or does not provide the desired details, the most effective way to verify the Blast Extreme configuration is to examine the log files on the virtual desktops, physical desktops, or RDSH servers. This means that some of the original image data is discarded (lost) as part of the compression process. 2 When RDP protocol is tunneled through the Connection Server or Security Server. captures the screen and handles everything within the session. Find assets to help you develop an adoption strategy that engages employees through careful messaging, education, and promotion. Using articles, videos and labs, this activity path provides the fastest way to learn Workspace ONE!

This guide is intended for IT administrators and implementors who want to provide end users with the best possible remote display experience. Set, Turn off audio unless absolutely required. These formats employ compression to reduce the size of the content before it is transferred across the network. Follow these guidelines: Note that while the optimizations in this section are typically used with WANs, they can also be used on the LAN if Blast Extremes default settings use more bandwidth or other resources than desired. This ensures that all systems deployed from these templates are configured properly for Blast Extreme. This provides increased scalability and better performance, especially in CPU-constrained ESXi environments without NVIDIA GPUs. The script will override the blast settings for users with an existing prefs.txt file without overriding the remaining settings. If desired, the traffic between Horizon Client and Horizon Agent can be configured to use a separate port (TCP 9427). SwitchEnc: 1 Screen 1 switching to h264 4:2:0 encoder. Deselect all other codecs and codec options. This capability not only provides a better user experience but also reduces the resources required for display protocol encoding overall. Ability to use either the TCP or the UDP network transport. Keep in mind, however, that Blast Extreme will always resort to using more bandwidth, if necessary, to prevent the session from crashing. (which like all VMware flings, is not officially supported). It also causes some screen content to letterbox, which may impair user experience. To collect logs on a Mac, you can use the. HEVC also requires clients to have graphics cards with H.265 decode support, but fortunately, as with H.264, most client devices manufactured since 2015 have them. High Efficiency Video Coding, or HEVC for short, is also known as H.265 and is the industry successor to H.264.
