Using articles, videos, and labs, this activity path provides the fastest way to learn Workspace ONE! It is extremely important to recognize that optimizing for higher quality nearly always results in more system resources being used, not less. Windows desktop and server operating systems are not designed for efficient virtualization. By design, Blast Extreme provides an excellent out-of-the-box user experience for typical applications and use cases on LANs. After comprehensive testing, we have determined that limiting frame rate provides little to no reduction in bandwidth or CPU utilization for typical applications and use cases. The following updates were made to this guide. However, it is important to note that building-to-lossless increases session bandwidth utilization because more display information is sent across the network. Note that this guidance does not include Metropolitan Area Networks (MANs) or similar LANs over long distance, which typically have as much, if not more, bandwidth than common user LANs. Note that this increases bandwidth and virtual desktop CPU utilization. If i look into the Settings of the vmware microphone, i can just choose between 8000 Hz and 16000 Hz (default is 8000Hz).

One of the goals for Blast Extreme 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. Guidelines when Troubleshooting Horizon Blast Protocol Performance UDP does not employ such controls and is therefore well suited for applications like streaming video and online gaming, which need to efficiently send large amounts of data to the client but can tolerate occasional errors. 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. For more information, see "VMware Blast Policy Settings" in the Horizon Remote Desktop Features and GPOs document. However, some use cases and situations require additional tuning, especially for wide area networks (WANs). This KB outlines the top trending cause associated with an intermittent external screen redirection issue with the Blast Protocol over Unified Access Gateway (UAG) Like HEVC, the encoding for H.264 and H.264 with HCA can be offloaded to NVIDIA GPUs installed in the ESXi hosts. (maximum display bandwidth) to either the circuit speed or the maximum desired bandwidth utilization per user.The former option allows Blast to burst and use more bandwidth when necessary, while the latter attempts to more strictly control it. End-users access to their personalized virtual desktops or remote applications from company laptops, their home PCs, thin client devices, Macs, tablets, or smartphones. If multimedia redirection (MMR) is enabled, this traffic uses TCP port 443 from the client to the Horizon Tunnel on the Unified Access Gateway. The following diagram shows the ports used for an internal tunneled connection, and the list that follows describes the order in which the connections are made. Blast Extreme will always resort to using more bandwidth, if necessary, to prevent the session from crashing. New in Horizon 8 (2106): HEVC with High Dynamic Range (HDR) Encoding. A TCP WebSocket connection is made on port 22443 between the client and the virtual desktop or RDSH server. 2. If desired, the traffic between the Unified Access Gateway and Horizon Agent can be configured to use a separate port (TCP 9427). Fortunately, this processing can be offloaded from the CPU to graphics cards (GPU) in the device. If you're experiencing display driver issues (such as a blank screen), before re-installing VMware Tools try forcibly removing the display driver. MinBandwidthKbp and MaxBandwidthKbps also impact all services, including audio and file transfer, while MaxBandwidthKbpsPerMegaPixelSlope only limits the bandwidth used to transfer the screen contents. Set. General settings include proxy options, time zone forwarding, multimedia acceleration, and other display settings.

Blast Extreme now supports four codecs: JPG/PNG, H.264, High Efficiency Video Coding (HEVC), and the new Blast Codec. Be sure to also leverage HTML5 multimedia redirection if browser-based HTML5 content must be supported. 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). VMware has developed a free tool to optimize Windows desktops and servers. The encoder switch switches the codec for an entire screen, not just a portion of a screen (screen region). If USB redirection is enabled, this traffic uses TCP 32111 between the client and agent. Same applications as for the JPG/PNG codec and the H.264 codec. On the client side, you can configure which codec or codecs to use for encoding and decoding the screen content transferred by Blast Extreme. For more information see Configuring HTML5 Multimedia Redirectionin Configuring Remote Desktop Features in Horizon 7. I'm sure this feature looked awesome on paper. With an internal tunneled connection, the client, the server, and the virtual desktop or RDSH server are all also inside the corporate network, but the clients might be on a different subnet from that of the virtual desktops or RDSH servers (where the agent is installed), and you do not want to open ports between the clients and agents directly. It is better to leverage HTML5 multimedia redirection to optimize such use cases. HEVC will not work with ESXi CPU encoding alone. These pages help you understand the breadth of our most popular products. hosts to support other tasks, which ultimately increases scalability. VNCEncodeRegionNvEncGetHandle: region encoder NVIDIA NvEnc H264 using YUV 4:2:0 color space. 2 When RDP protocol is tunneled through the Connection Server or Security Server. And if Blast Extreme encounters problems making its initial connection over UDP, it will automatically switch and use TCP for the session instead. Tuning to handle high latency starts with reducing bandwidth. HEVC also requires a client device capable of HEVC GPU decoding. It also causes some streaming video to letterbox, which may impair user experience. This guide is intended for IT administrators and evaluators who are familiar with VMware Horizon and VMware vSphere. If multimedia redirection (MMR) is enabled, this traffic uses TCP port 9427 between the client and agent. (Requires NVIDIA GPU), VNCRegionEncoder_Create: region encoder NVIDIA NvEnc H264. Ensure that ESXi hosts have sufficient resources, especially CPU. If the testing in your environment is not successful, use JPG/PNG. Type: REG_SZ. 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. High Efficiency Video Coding (HEVC). HEVC supports higher-quality imaging with less bandwidth utilization than H.264.
