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. The evaluation process has been initiated. Horizon Client supports H.264 software encoding and hardware decoding on the following types of clients: Horizon Client also supports High Efficiency Video Coding, or HEVC for short. VMware made the DPI setting on the client device leading and adjusts the remote desktop accordingly. H264maxQP The lowest quality that H.264 will start with before building the screen to higher quality. JpegQualityHigh The highest quality that JPG/PNG will achieve. Activity Paths are guided and curated learning paths through modules and activities that help you cover the most content in the shortest amount of time. 1 In VMware Horizon, when using PCoIP Secure Gateway on the Connection Server or Security Server. TCP port 32111 is then used between the Unified Access Gateway and agent. Configuration Settings for Administrators, Tuning Blast Extreme for Wide Area Networks, Guidance for Work-from-Home and Home-Office-to-Cloud Use Cases, VMware Horizon Cloud Service on Microsoft Azure, A solid understanding of desktop and application virtualization, A good working knowledge of networking and infrastructure, covering topics such as Active Directory, Group Policy, and supporting technologies. By default the encoder and decoder caches are set to 256 MB. 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. Configuring Remote Desktop Features in VMware Horizon, Enabling the USB Over Session Enhancement SDK Feature. They are designed to have something for people of every experience level. Information on how to enable the new Blast Codec is covered in the next chapter, How to Configure Blast Extreme. This guide is intended for IT administrators and evaluators who are familiar with VMware Horizon and VMware vSphere. The port used by the Blast Secure Gateway on the Unified Access Gateway can be customized (for example, it can use TCP 443). This will reduce both network bandwidth and CPU utilization. It also causes some screen content to letterbox, which may impair user experience. Typical Microsoft Office use, for example, results in a very low display protocol frame rate. These settings apply to HTML Access and all Horizon Client platforms. Caroline Arakelian is a Senior Technical Marketing Manager, End-User-Computing Technical Marketing, VMware. TCP 443 is used between the client and the Connection Server. This means that some of the original image data is discarded (lost) as part of the compression process. Optimize the Windows operating system in virtual desktops and RDSH servers using the VMware Operating System Optimization Tool, but recognize that some optimizations applied by default might reduce quality or turn off features required to support higher-quality applications. This is also due to a limitation of desktop-class video drivers. Although it has more of an impact on multimedia and video gaming, experiment with different values, up to the maximum of. Depending on application workload, 4K displays can use up to six times the resources as 1080P. Essa conexo fornece o nvel necessrio de segurana e conectividade ao . Navigate to Virtual Machine > Settings (Fusion) or VM > Settings (Workstation). Except under unique conditions, it is not possible to increase quality while limiting system resources. However, some use cases and situations require additional tuning, especially for wide area networks (WANs). MaxBandwidthKbpsPerMegaPixelSlope The maximum bandwidth used to transfer screen contents per megapixel remoted, in kilobits per second. When client-drive redirection (CDR) is enabled by the administrator, by default, the traffic is side-channeled on the Blast Extreme channel. Horizon Client, installed on the client device, connects to a Connection Server on TCP port 443 for authentication and to request a desktop or application. Note: for all settings in the following table, if the key is set to 1 support is enabled; if it is set to 0 support is turned off. And if Blast Extreme encounters problems making its initial connection over UDP, it will automatically switch and use TCP for the session instead. See our favorite tools, scripts, and flings from various sites. Customize your Workspace ONE and Horizon adoption communications using our templates as a starting point. To use Blast Extreme, the virtual or physical desktop pool or RDSH server farm must first be configured to use the protocol as the default, or be configured to allow users to choose it. See the faces behind the names of our Tech Zone content. The latest innovation for Blast Extreme is the Blast Codec. High Efficiency Video Coding (HEVC). It is extremely important to recognize that optimizing for higher quality nearly always results in more system resources being used, not less. If full-motion graphics must be supported, such as streaming video, use the encoder switch to dynamically switch between the Blast Codec or JPG/PNG and the H.264 codec. 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. The descriptions mention various remote experience features. If UDP is enabled on the agent (default), the Blast Proxy process (in Horizon Agent) attempts to make a UDP WebSocket connection to the client on port 22443. The following table documents the key codec and transport settings. Diagrams show which ports are used at which locations, and the numbered lists that follow the diagrams show what is happening at each connection. 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. Same applications as for the Blast Codec and the H.264 codec. If UDP is not enabled or is blocked, the initial TCP connection (Step 3) is used instead. Create desktop pools, application pools, or both. 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. This Continued On the VM registry I configured the following GPO values: In addition, I also tried to manually configure this registry setting: Configuring the Client Clipboard Memory Size (value of 8192 decimal) [despite the fact that is was configured in the above GPO When viewing the Blast logs on the VM I see the following entry: Blast-Worker-SessionId1.log The Blast Codec was designed to be the ideal codec for these types of applications. 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. What about frame rate? Yes. HDR: Relative Brightness of the Paperwhite Level. Go to https://my.vmware.com/web/vmware/downloads. The image formats used by these codecs employ compression to reduce the size of the content before it is transferred across the network. For external connections: Unified Access Gateway 2.9 or later. Chris is EUC Staff Architect, End-User-Computing Technical Marketing, VMware. If multimedia redirection (MMR) is enabled, this traffic uses TCP port 9427 between the client and agent. Chris Halstead co-authored the original version of this white paper. Blast Extreme must be on TCP 443 only (as described previously for port sharing). Now that you have learned about the benefits and features of Blast Extreme and have seen how easy it is to configure in your Horizon environment, we hope that you will take advantage of this adaptive and purpose-built display protocol. Learn how to architect the right security solutions for your business needs. The Blast Worker process ( VMBlastW.exe) captures the screen and handles everything within the session. Note: This parameter does not impact the bandwidth of other services such as audio and file transfer, which are unrelated to transfer of the screen. VMware has built a set of tools and resources to support you and your team as you build out an adoption strategy. We have many more paths than are shown here. Monitor for high CPU Ready times (which are evidence of processor contention). If bandwidth needs to be limited, start with the. VMware Blast performance and end-user experience acceleration Blast is now the new default. Use TCP if latency is greater than 250 milliseconds. 3 enable file download only, 0 turned off in both directions This means that display content encoded and compressed using PNG alone can be restored to match the quality of the original content. Note: Requires Horizon Agent 7.10 and Horizon Client 5.2 or later. Entitle users to desktops and published applications. The actual size of the cache will be the lesser of this value, and the value of DecoderImageCacheSizeKB set on the client but cannot exceed half of the available RAM. (which like all VMware flings, is not officially supported). If USB redirection is enabled, this traffic uses TCP 32111 between the client and agent. format. 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. Deselect all other codecs and codec options. Like HEVC, the encoding for H.264 and H.264 with HCA can be offloaded to NVIDIA GPUs installed in the ESXi hosts. Log File Locations for Client and Agent Components, Software Requirements for Physical Desktop Machines. There are a couple of logs you can look at that will give you Blast Extreme related information: C:\ProgramData\VMware\VMware Blast\ Blast-Service.log. Yes: Select Allow H.264 Decoding. Update for VMware Horizon 7 version 7.10. EncoderMaxFPS The maximum frames per second that Blast Extreme will display. Deselect all other codecs and codec options. By default, Blast Extreme is capped at 30 frames per second (FPS). Used together, the JPG/PNG codec is ideally suited for typical Windows and Linux applications, including Microsoft Office. Start here to understand the basics of the award-winning product suite. Navigate the sophisticated world of Unified Access Gateway (UAG) for Workspace ONE and Horizon 8. Note: Dynamic Environment Manager also provides optimization templates for Blast Extreme. Typical productivity applications such as Microsoft Office, plus those requiring support for fine details and higher still image quality. Some tradeoff in system configuration, supportable applications, and user experience is to be expected. Figure 5: Path in the Group Policy Editor for Turning On the Microsoft Teams Optimization Feature Double-click to open and turn on the policy. Many of the codec options and Blast Extreme settings can be controlled by administrators. I ended up writing a logon script to solve the problem until VMware fixes it. EncoderHEVCEnabled Enables or turns off support for the HEVC codec (H.265). In the client VMware Blast settings, Allow High Efficiency Video Decoding (HEVC) and Allow High Dynamic Range Decoding (HDR) needs to be turned on. Like the codec and transport options, they can be set using Group Policy or using your preferred method of making registry changes.
