This is great for users that use their own devices with all kinds of displays and DPI settings and such. 2. However, in testing it has been determined that only Intel GPUs support OpenGL applications in a remote session. Note: For more information about internal client connections, see Network Ports in VMware Horizon. For details about port requirements for connectivity between the various components and servers in a Horizon deployment, see Network Ports in VMware Horizon. On the client side, you can configure which codec or codecs to use for encoding and decoding the screen content transferred by Blast Extreme. 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. 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). These efficient purpose-built thin clients offer ultrafast access to applications, files, and network resources within Virtual Desktop Infrastructure (VDI) environments. setting, which limits only the display traffic without negatively impacting audio, file transfer, or other supporting services. Most configuration settings can be made directly in the Windows Registry of each virtual and physical desktop and RDSH server using your preferred tool for making such registry changes. Do not attempt to support high-quality use cases over a WAN or poorly functioning network. A stated goal in the VMware Horizon documentation is "to provide an excellent out-of-the-box configuration for most local area network (LAN) use cases, negating the need to perform complex tuning or learn hundreds of policy settings." VMware notes that "some use cases and situations require additional tuning, especially for wide area networks . At Tech Zone, our mission is to provide the resources you need, wherever you are in your digital workspace journey. In testing, viewing a YouTube video in a standard window instead of full-screen reduced bandwidth utilization by 53 percent. Be certain to test key applications and multimedia content before embarking on widespread deployment. You should have: In order to optimize Blast Extreme, it is important to understand two key configurable components: the transport protocol and display protocol codec. When helping customers troubleshoot poorly performing infrastructures, VMware Professional Services routinely finds that the virtual desktops have not been sized properly and are consequently running out of critical resources such as virtual CPUs. MaxBandwidthKbps The maximum bandwidth used by all services (display, keyboard and mouse, audio, file transfer, clipboard, and so on), in kilobits per second. After you apply the policy, the system stores the settings in the registry key HKLM\Software\Policies\VMware, Inc.\VMware Blast\config. VNCRegionEncoder_Create: region encoder h264 4:2:0. However, this example can be achieved by disabling support for the H.264 codecs competing options: JPG/PNG and HEVC. Tunneling traffic through the Connection Server allows for ports to be open between the Connection Server and the client, and between the Connection Server and the agent, but not between the client and the agent. Instructions for configuring all of the Blast Extreme codec options are provided in the next chapter, How to Configure Blast Extreme. With non-multimedia workloads, the Blast Codec uses the least bandwidth compared to all other codec options. Create desktop pools, application pools, or both. Start here to understand the basics of the award-winning product suite. Introduced in Horizon 8 (2111) is the ability to adjust the size of the Blast codec cache. EncoderH264YUV444 Enables or turns off support for High Color Accuracy for H.264. 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. Consider using HCA for H.264 with the encoder switch to dynamically match the highest-quality H.264 configuration with the Blast Codec or JPG/PNG. :\ProgramData\VMware\VMware Blast\. The same workload on a 4K display requires up to six times the resources required by 1920 x 1080p, regardless of display protocol and codec used. VNCEncodeRegionNvEncGetHandle: region encoder NVIDIA NvEnc H264 using YUV 4:4:4 color space. While the JPG algorithm attempts to remove only redundant data, in practice other data is lost as well. It also causes some screen content to letterbox, which may impair user experience. The Horizon Client authenticates to a Connection Server through the Unified Access Gateway. In other words, the settings do not directly enable the feature, such as forcing all connections to use H.264. It may be a good idea to completely uninstall VMware Tools and re-install. NVIDIA H.264 with HighColorAccuracy Keep in mind that MinBandwidthKbp and MaxBandwidthKbps also impact all services, including audio and file transfer, while MaxBandwidthKbpsPerMegaPixelSlope only limits the bandwidth used to transfer the screen contents. Although it has more of an impact on multimedia and video gaming, experiment with different values, up to the maximum of. The client-side settings work in conjunction with the agent-side settings, which administrators can configure, as described in How to Configure Blast Extreme, in the VMware Blast Extreme Optimization Guide. With an internal connection, the client, the server, and the virtual desktop or RDSH server are all inside the corporate network. 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. By Peter Brown, Senior R&D Manager, and Tarique Chowdhury, Software Engineer For information about what's new with Horizon Real-Time Audio-Video, read this 2023 blog. In this file, add the single line: RemoteDisplay.allowClientBlastCodec = TRUE. Let us help you become the hero of your department. 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). Running traditionally full-screen applications in a window instead of full-screen can also slash bandwidth utilization. But when rapidly changing screen content such as streaming video is detected, Blast Extreme automatically switches to multimedia optimized H.264. This section details the workflow of connections that are made so that Blast Extreme can provide the best remote display experience, regardless of whether the user is inside or outside of the corporate network. Workspace ONE Access, formerly known as Identity Manager, is a powerful tool. Note: For more information about external client connections, see Network Ports in VMware Horizon. What about frame rate? 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. The former option allows Blast Extreme to burst and use more bandwidth when necessary, while the latter attempts to more strictly control it. Watch conversations with VMware experts on top-of-mind issues. In testing with a single 4K display, viewing a typical YouTube video in standard windowed mode used 53 percent less bandwidth and 23 percent less virtual desktop CPU than watching the same video full-screen. JPG/PNG can also be configured to use build-to-lossless mode. Blast Extreme supports two transport protocols to carry the display traffic between clients and the Horizon infrastructure: TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). : NVIDIA GPUs will also offload H.264 and HEVC encoding. This step-by-step setup of VSs leverages the Kemp application template for Horizon 7 and Horizon 8. In this mode, the codec is able to support applications that require the display protocol to be lossless, ensuring nothing is lost in transmission. Provide a hardware GPU to support graphically demanding applications such as 3D design, gaming, and photo editing. The next section describes the workflow of connections made between the client and agent components. Blast Extreme is a next-generation display protocol, developed by VMware. The encoder switch dynamically switches between either the JPG/PNG codec or the Blast Codec, and H.264, depending on the screen content type. With the exception of Build-to-Lossless which impacts all screens at all resolutions, each logfile entry denotes the codec used, the number of the screen (monitor) being configured of the total number, and its display resolution. Log File Locations for Client and Agent Components Applications that require the same quality as H.264 with less bandwidth utilization or that require higher quality with similar bandwidth utilization as H.264. This will reduce both network bandwidth and CPU utilization. For a detailed list of Blast Extreme features, see the VMware Blast Extreme topic in the VMware Horizon Architecture Planning guide. General Settings The following table describes the general settings in the Horizon Client Configuration ADMX template file. Work with network partners and circuit providers to fix the network. Entitle users to desktops and published applications. These pages help you understand the breadth of our most popular products. Screen 0/1 @ Resolution: 3840 x 2160. Note: This additional color information with HCA increases session bandwidth utilization by 5 percent on average. 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 following settings are specifically helpful for handling low-bandwidth conditions: Note that these minimum and maximum bandwidth settings are best effort, not hard limits. If extensive use of graphically intensive content such as streaming video must be supported, consider asking users to view this content in a window, instead of full-screen mode. EncoderNvidiaH264Enabled Enables or turns off support for offloading H.264 encoding to NVIDIA GPUs installed in the ESXi hosts. Keep in mind, however, that Blast Extreme will always resort to using more bandwidth, if necessary, to prevent the session from crashing. Find all of TechZone's available downloadable content here. Although RAM is rarely the bottleneck, monitor RAM to ensure it is not being over utilized by applications.
