Utilize this tool to get you part of the way there. Display resource-intensive multimedia content in a window instead of full screen. The VMware Workspace ONE and Horizon Reference Architecture guide provides guidance for architecting Workspace ONE and Horizon deployments. Even when there might be sufficient bandwidth, such as for a home-based user with a high-speed cable network connection, be certain to validate end-to-end bandwidth, latency, and packet loss before deciding if the use case can be supported. It turns off or tunes the elements that unnecessarily waste system resources when used in shared, virtual environments. Same applications as for the JPG/PNG codec and the H.264 with HCA codec. 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. Developed for a variety of workloads, Blast is optimized for an ideal user experience and resource consumption. Moving to the cloud? MainApp::OnEncoderConfigChanged: Encoder config changed: EncoderBuildToPNG = 1. There is two files in this directory C:\ProgramData\Vmware\Vmware Blast: blast-service.log. 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. Blast Extreme must be on TCP 443 only (as described previously for port sharing). 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. It also causes some screen content to letterbox, which may impair user experience. To provide secure access from external locations and over the Internet, VMware Unified Access Gateway is deployed to provide secure edge services. After you apply the policy, the system stores the settings in the registry key HKLM\Software\Policies\VMware, Inc.\VMware Blast\config. Note: For more information about internal client connections, see Network Ports in VMware Horizon. Be sure to also leverage HTML5 multimedia redirection if browser-based HTML5 content must be supported. Turn on the sound card: Fusion 7.x and above: Ensure Connect Sound card option is checked. Welcome to VMware Digital Workspace Tech Zone, your fastest path to understanding, evaluating, and deploying VMware End User Computing products. The Blast Worker process ( VMBlastW.exe) captures the screen and handles everything within the session. Horizon Agent 7.5 or later is required; Horizon Agent 7.10 or later is recommended. At Tech Zone, our mission is to provide the resources you need, wherever you are in your digital workspace journey. Horizon Client, on the client device, connects to a Connection Server on TCP port 443 for authentication and to request a desktop or application. Start here to understand the basics of the award-winning product suite. In testing, viewing a YouTube video in a standard window instead of full-screen reduced bandwidth utilization by 53 percent. 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. In testing this has been shown to decrease the amount of network bandwidth used by Blast Extreme. Do not attempt to support high-quality use cases over a WAN or poorly functioning network. However, it is a new and rapidly evolving codec. Figure 1: Blast Extreme Settings on Horizon Client for Windows. Use the new Blast Codec plus H.264 with the encoder switch to provide efficient support for nearly all work-from-home and home-office-to-cloud use cases. Access technical, third-party tips, tricks, and how-tos. 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. 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. There is a unified image quality configuration setting that controls the remoted display image quality level across all Blast encoders. There are some special considerations when supporting work-from-home and home-office-to-cloud use cases: The other common reason to tune display protocols is to increase quality. These efficient purpose-built thin clients offer ultrafast access to applications, files, and network resources within Virtual Desktop Infrastructure (VDI) environments. The fewer packets the display protocol puts on the network, the fewer that will be affected by packet loss. 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. Special note about NVIDIA GPU supported use cases: Using NVIDIA GPUs to support H.264 and High Efficiency Video Coding (HEVC) substantially increases session bandwidth. Display communication protocols provide end users with a graphical interface to a remote desktop or published application. (Requires NVIDIA GPU), VNCRegionEncoder_Create: region encoder NVIDIA NvEnc H264. More information about the admin settings is provided in the next section of this chapter. Join the community by engaging in forums, events, and our premier community programs. Horizon Client 5.2 requires a special client setting. Explore the latest VMware tools designed to get your end-user computing environment running smoothly and efficiently. The encoder switch ensures that the most efficient codec is dynamically used based on screen content. With Horizon 7 version 7.12, support for using Blast Extreme with physical desktop machines running Windows 10 versions 1903 and later was added. This gateway then directs the traffic to the correct port and location on the Connection Server and agent. The range is 136, where 1 is the highest quality. Horizon Client version 5.2 only also requires a special configuration file on the client (see the note following this table). Workspace ONE Access, formerly known as Identity Manager, is a powerful tool. General settings include both Computer Configuration and User Configuration settings. Except under unique conditions, it is not possible to increase quality while limiting system resources. Use a single monitor with the lowest screen resolution supported by the use case. HEVC requires NVIDIA GPUs to be installed in the ESXi hosts to offload encoding. Note: Setting this option to 100 will not provide a lossless image. Entitle users to desktops and published applications. 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. See the faces behind the names of our Tech Zone content. Then select the appropriate Horizon version and click Go To Downloads. Added information about the Blast Codec, which was introduced in the Horizon 7.10 release, and new information about the encoder switch. Deselect all other codecs and codec options. This can result in H.264 being used for one display and JPG/PNG or the Blast Codec being used for another simultaneously. Streaming video, for example, may freeze for a moment or pixelate briefly, but otherwise continue playing. Limiting the resolution of employees monitors also greatly reduces Internet circuit bandwidth utilization. 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. JPG/PNG and H.264 with HCA. The following table provides guidance on which codecs to use for various types of applications. The App Volume Manager is a console for managing configuration, creation of AppStacks, and assignment of AppStacks and writable volumes. These settings are used to configure the address at which clients can reach the specific server when tunneling is in use. Using articles, videos, and labs, this activity path provides the fastest way to learn Workspace ONE! Test the new Blast Codec unless this use-case is primarily in support of full motion video or high-speed motion graphics such as gaming. VNCRegionEncoder_Create: region encoder h264 4:2:0. 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. These settings determine a virtual webcam's maximum frame rate and image resolution. Deploy virtual desktops and RDSH servers on fast virtual disks (all-flash or flash-optimized). Using articles, videos and labs, this activity path provides the fastest way to learn Workspace ONE! Therefore, images compressed using JPG cannot be decoded and restored to the same quality they had before compression. My email is nikoloz.qutidze@gmail.com Many of the codec options and Blast Extreme settings can be controlled by administrators. 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. Specializing in IT architecture on every scale, Mark has designed hundreds of successful solutions for organizations of all sizes and verticals. Most Macs, laptops, and Windows PCs manufactured in 2013 or later. The following updates were made to this guide. Be certain to test key applications and multimedia content before widespread deployment. Added guidance on using Network Quality-of-Service (Qos) to prioritize Blast. 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). The Horizon Performance Tracker does not currently indicate HCA mode when NVIDIA encoding is used. Fortunately, Blast Extreme supports the H.264 codec for precisely this type of content. Visit these other VMware sites for additional resources and content. Note that HDR is an optional capability of HEVC (High Efficiency Video Coding, H.265) and requires an NVIDIA hardware GPU. Monitors with higher screen resolutions, and use cases with multiple monitors, require more system resources, especially CPU and network bandwidth. 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. And if Blast Extreme encounters problems making its initial connection over UDP, it will automatically switch and use TCP for the session instead. While typically supporting just a single user, most households do not yet have LAN-speed Internet connections (gigabit Ethernet). TCP, the most common transport protocol on the Internet, has built-in data integrity checking and control to ensure that packets arrive at their intended destination without errors. These components include the transport protocol and display protocol codec: For details about the various transport protocols, codecs, image formats, and types of compression that Blast Extreme uses, depending on the type of screen content, see Blast Extreme Technology, in the VMware Blast Extreme Optimization Guide. When client-drive redirection (CDR) is enabled by the administrator, by default, the traffic is side-channeled on the Blast Extreme channel. The actual size of the cache will be the lesser of this value, and the value of EncoderImageCacheSizeKB set on the agent side but cannot exceed half of the available RAM. Screen 0/1 @ Resolution: 3840 x 2160. Use HTML5 multimedia redirection if resource-intensive web-browser-based content such as YouTube or eLearning streaming video must be supported. These pages help you understand the breadth of our most popular products. Test the new Blast Codec. It is important to recognize, however, that no display protocol can provide a perfect LAN experience over typical WANs. Problem is with second file, which is growing sometimes up to 15GB, then new files are created. Information on how to enable build-to-lossless mode is covered in the next chapter, How to Configure Blast Extreme. The VMware Blast service ( VMBlastS.exe) manages user sessions, proxies incoming TCP connections, and prepares the Blast Worker process. Added information about OpenGL and DirectX compatibility with hardware GPUs in remoted physical PCs. 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.
