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 Connection Server returns connection information for the virtual desktop or RDSH server that provides remote applications (on TCP port 443). As its name implies, the JPG/PNG codec leverages two image formats, JPG and PNG, to encode and decode display content. Fortunately, Blast Extreme supports the H.264 codec for precisely this type of content. H.264s 4:4:4 GPU decoding is also not supported by many GPUs. The Horizon Clients can use either IP version 4 or 6. Same applications as for the Blast Codec and the H.264 codec. Learn how to architect the right security solutions for your business needs. (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. VMware Blast Extreme Group Policy Settings The policy files required are vdm_blast.admx and vdm_blast.adml. It also causes some screen content to letterbox, which may impair user experience. Utilize this tool to get you part of the way there. 2. Limiting the resolution of employees monitors also greatly reduces Internet circuit bandwidth utilization. Although it has more of an impact on multimedia and video gaming, experiment with different values, up to the maximum of. Join the community by engaging in forums, events, and our premier community programs. Fortunately, Blast Extreme can be tuned to handle all of these situations. A consistent user experience across devices and locations while keeping corporate data compliant and securely stored in the data center. Get all the Tech Zone demos in one place. Here you can create an account, or login with your existing Customer Connect / Partner Connect / Customer Connect ID. TCP 443 is used between the client and the Connection Server. With the Horizon 2106 release, we also announced support for the NVIDIA Ampere A10 and A40 GPUs. To provide secure access from external locations and over the Internet, VMware Unified Access Gateway is deployed to provide secure edge services. High Efficiency Video Coding (HEVC) It is remarkable that this setup can be made to work over a WAN at all! After the policy is applied, the settings are stored in the registry key HKLM\Software\Policies\VMware, Inc.\VMware Blast\config. Blast Extreme is a display protocol built by VMware to deliver an immersive, feature-rich experience for end users across devices, locations, media, and network connections. 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. Be certain to test key applications and multimedia content before widespread deployment. And limiting frame rate for multimedia use cases such as streaming video simply impairs playback quality and user experience. Get to know EUC vExperts from around the world. For more information, see, Worksheet for Creating an Automated Instant-Clone Farm, Setting Up Published Desktops and Applications in Horizon, To configure the remote display protocol at the global entitlement level, see, Administering Cloud Pod Architecture in Horizon. It is designed to support the majority of customer use cases, including not just typical Windows and Linux apps like Microsoft Office, but also SaaS applications, line-of-business apps like Point of Sale, plus any that require low-motion, high-quality graphics support such as CATIA, Photoshop, and AutoCAD. Accepts integer value greater than 0. hosts to support other tasks, which ultimately increases scalability. Keep in mind that this may complicate WAN use cases. VNCRegionEncoder_Create: region encoder h264 4:2:0. For lossless support, enable Build-to-Lossless (EncoderBuildToPNG = 1). This will allow Horizon to allocate between 125 MB and 128 MB of video memory to each virtual desktop. On the Security Server, run the downloaded VMware-Horizon-Connection-Server-x86_64-7.13.2.exe. 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. This will force H.264 to start at higher quality and prevent it from expending bandwidth to send initial low-quality screens. Although this results in a similar reduction in the network bandwidth required, it uses substantially more CPU processing power to encode and decode. Blast gateway not running when a Certificate generated from IIS is used (89820) - This article outlines a scenario where a generated certificate key cannot be read and Blast fails. 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). Graeme Gordon is a Senior Staff End-User-Computing Architect, EUC Technical Marketing, VMware. Information on how to enable build-to-lossless mode is covered in the next chapter, How to Configure Blast Extreme. For more information, see. But it can also be used to support graphically intensive applications by leveraging the desktops physical GPU. Figure 1: Choosing Blast Extreme in the Horizon Client Options. (maximum display bandwidth) to the maximum desired bandwidth utilization per user. You can increase the rate, up to 60 FPS, by using the Windows Registry setting. These settings apply to HTML Access and all Horizon Client platforms. Welcome to VMware Digital Workspace Tech Zone, your fastest path to understanding, evaluating, and deploying VMware End User Computing products. 1 enable upload and download This will reduce both network bandwidth and CPU utilization. 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. Turn on the sound card: Fusion 7.x and above: Ensure Connect Sound card option is checked. Although this strategy makes for reliable delivery, the process adds overhead. Be certain to test key applications and multimedia content before widespread deployment. 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. Horizon Client 5.2 requires a special client setting. By default the encoder and decoder caches are set to 256 MB. At Tech Zone, our mission is to provide the resources you need, wherever you are in your digital workspace journey. 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. JPG/PNG can also be configured to use build-to-lossless mode. For details about editing View Connection Server settings and security server settings, see the VMware Horizon View Administration documentation. Find all of TechZone's available downloadable content here. However, it is important to note that building-to-lossless increases session bandwidth utilization because more display information is sent across the network. If the testing is not successful, use JPG/PNG. Begin your journey leveraging cloud-based services for desktop environments. Use HTML5 multimedia redirection if resource-intensive web-browser-based content such as YouTube or eLearning streaming video must be supported at high screen resolutions without NVIDIA GPUs. Is there a GPO or something? In testing, viewing a YouTube video in a standard window instead of full-screen reduced bandwidth utilization by 53 percent. NVIDIA, including GTX 10xx and 20xx series models, AMD, including Radeon RX and Vega RX models, Intel, including Intel HD Graphics 530, UHD Graphics 620, and Iris Plus Graphics 650. 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. Let us help you become the hero of your department. Access technical, third-party tips, tricks, and how-tos. Access technical, third-party tips, tricks, and how-tos. In testing, video gaming workloads have been routinely benchmarked performing at 60 FPS. Support full-motion video at 4K display resolution or above without HTML5 redirection. If the primary use-case is full motion video or high-speed motion graphics such as gaming, use the H.264, H.264 with High Color Accuracy or High Efficiency Video Coding (codecs), offloaded to an NVIDIA Tesla or newer GPU. In testing this has been shown to decrease the amount of network bandwidth used by Blast Extreme. To enable the new feature, you need to set this registry key on your VDI machine: Key: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\VMware, Inc.\VMware Blast\Config\EncoderSwitchEnabled. Do not starve the virtual desktops and RDSH servers of resources. Note: Setting this option to 100 will not provide a lossless image. 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. This is due to the much higher graphical quality this hardware-enabled configuration provides. 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. Yes. Watch conversations with VMware experts on top-of-mind issues. Deselect all other codecs and codec options. Testing has shown this enables smooth 4K video playback without need for hardware GPUs. Encoder Switch: Blast Codec and H.264 with HCA. TCP port 9427 is then used from the Unified Access Gateway to the agent. To verify operation, examine the logs. Yes: Deselect all codecs and codec options (uncheck: H.264, Allow High Color Accuracy, and Allow High Efficiency Video Coding). Used together, the JPG/PNG codec is ideally suited for typical Windows and Linux applications, including Microsoft Office. The Blast Codec should be evaluated for use whenever network bandwidth or display protocol CPU utilization is a primary concern. If USB redirection is enabled, this traffic uses TCP 32111 between the client and agent. However, if the network also supports interactive video, Blast Extreme is often marked one-level lower with a DSCP marking of AF31. This guide is intended for IT administrators and implementors who want to provide end users with the best possible remote display experience. By default, they are expected to be installed on dedicated, physical hardware, and not separated from their intended users by networks and display protocols. While most of our environment is running PCoIP, we have also tested with BLAST. In the client VMware Blast settings, Allow High Efficiency Video Decoding (HEVC) and Allow High Dynamic Range Decoding (HDR) needs to be turned on. This means that some of the original image data is discarded (lost) as part of the compression process. End-users access to their personalized virtual desktops or remote applications from company laptops, their home PCs, thin client devices, Macs, tablets, or smartphones. 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. This means the client resorts to CPU decoding, which can result in degraded performance on weak client hardware, particularly when using high-resolution monitors. The VMware Operating System Optimization Tool can be downloaded from, https://flings.vmware.com/vmware-os-optimization-tool. There are several ways that these settings can be applied. WANs typically have just a fraction of the bandwidth that is available on local area networks (LANs). I ended up writing a logon script to solve the problem until VMware fixes it. Use cases of this caliber nearly always require hardware GPUs to provide the necessary graphics capabilities and acceleration. Display communication protocols provide end users with a graphical interface to a remote desktop or published application. TLS version and encryption defaults are routinely updated to reflect current best practices. 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. 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. Offload H.264 and High Efficiency Video Coding (HEVC) encoding from the ESXi hosts. Set on the virtual desktop and RDSH server (agent side). The port used by the Blast Secure Gateway on the Unified Access Gateway can be customized (for example, it can use TCP 443). One of the easiest methods is to use the Windows Group Policy template provided with each release of VMware Horizon. 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. 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). The traffic uses the native port for each of the remote experience features between the Connection Server and the agent: With an external connection, the client is connecting from outside the corporate network to the Unified Access Gateway. Yes: Select Allow H.264 on the client. There is a unified image quality configuration setting that controls the remoted display image quality level across all Blast encoders. By default, H.264 in Blast Extreme uses a 4:2:0 sample rate, with the 2:0 indicating that only a quarter of the information about image color is included, compared to HCAs 4:4:4. 3 enabled server to client only. 2 enable file upload only VMware built Blast Extreme to handle even the most demanding graphical workloads, including medical imaging and designing geographic information systems (GIS) applications used for analyzing large data sets, creating maps, and visualizing scenarios of the outside world, in both 2D and 3D. The connection continues from the Unified Access Gateway to UDP port 22443 on the agent. Find all of TechZone's available downloadable content here. Using articles, videos and labs, this activity path provides the fastest way to learn Workspace ONE! Blast Extreme now supports four codecs: JPG/PNG, H.264, High Efficiency Video Coding (HEVC), and the new Blast Codec. DecoderImageCacheSizeKB Introduced in Horizon 8 (2111).Set on the client. (which like all VMware flings, is not officially supported). 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). Blast Extreme is a next-generation display protocol, developed by VMware. Use Group Policy to prohibit use of desktop wallpaper. This means most should be considered medium- to high-speed WAN use cases. Workspace ONE Access, formerly known as Identity Manager, is a powerful tool. Horizon Cloud on Microsoft Azure Activity Path. Log File Locations for Client and Agent Components By default, Blast Extreme is capped at 30 frames per second (FPS). It is important to recognize, however, that no display protocol can provide a perfect LAN experience over typical WANs. Most settings make the option available to be used (set to 1) or not (set to 0).

HEVC also requires clients to have physical GPUs with H.265 decode support, but fortunately, as with H.264, most client devices manufactured since 2015 have them. Streaming video, for example, may freeze for a moment or pixelate briefly, but otherwise continue playing. Horizon Client 4.8 or later is required; Horizon Client 5.2 or later is recommended. Entitle users to desktops and published applications. For more information, see Configuring HTML5 Multimedia Redirection in Configuring Remote Desktop Features in Horizon 7. General Settings for Virtual Machines Blast Extreme can also use the certificate thumbprint of the Blast Secure Gateway or virtual desktop. Tuning to handle high latency starts with reducing bandwidth. SwitchEnc: 1 Screen 1 switching to h264 4:2:0 encoder. To observe this in action we can control the codec selection using the VMware Blast settings on the Horizon client. Let us help you become the hero of your department. EncoderNvidiaH264Enabled Enables or turns off support for offloading H.264 encoding to NVIDIA GPUs installed in the ESXi hosts. Get to know and understand the Anywhere Workspace solution. HCA turns off 4:2:0 chroma subsampling, providing a 4:4:4 sample rate instead. Explore custom assets and resources for federal, state, and local government framework solutions here, including industry-leading, public-sector solutions for endpoint management security, virtualization, cloud, and mobile, commercial requirements, industry standards, government certification, and accreditation programs. FIPS-ready libraries are available for Unified Access Gateway 2.9 or later appliances. Added information about the Blast Codec, which was introduced in the Horizon 7.10 release, and new information about the encoder switch. The VMware Blast ADMX template file ( vdm_blast.admx) contains policy settings for the VMware Blast display protocol. This means that display content encoded and compressed using PNG alone can be restored to match the quality of the original content. Question: 1. Fortunately, VMware has developed a free tool to optimize Windows desktops and servers. For extreme low-bandwidth, high-latency, or high-performance uses cases, however, Blast Extreme comes equipped with several tuning options, as described in this guide. Information on how to enable the new Blast Codec is covered in the next chapter, How to Configure Blast Extreme. This configuration is ideal for digital photography, design, and video production but requires an NVIDIA hardware GPU to support HEVC. Still, when logged into a virtual machine, there is no improvement to the quality of the picture when run on a Thin Client. Critical Horizon features and components, such as the Blast Extreme display protocol, instant-clone provisioning, VMware App Volumes application delivery, and VMware Dynamic Environment Manager , are integrated with published applications and desktops to provide a seamless user experience and an easy-to-manage, scalable solution. USB redirection traffic can also be side-channeled in the Blast Extreme port. Remember that you are separating the user and their keyboard, monitor, and mouse from the system they are actually using. This can help determine the best architecture, understand the traffic flow, and network ports, and help in troubleshooting. Although Blast Extreme is designed to provide an excellent, out-of-the-box configuration for most use cases, some network conditions and applications require additional tuning. Horizon is a complete solution that delivers, manages, and protects virtual desktops, RDSH-published desktops, and applications across devices and locations. When multimedia redirection (MMR), client-drive redirection (CDR), USB redirection, or some combination of these are enabled by the administrator, this traffic goes through the HTTPS Secure Tunnel on the Connection Server. For a detailed list of Blast Extreme features, see the VMware Blast Extreme topic in the VMware Horizon Architecture Planning guide. Join the community by engaging in forums, events, and our premier community programs. The VMware virtual desktop pool setting in the Horizon administrative console You'll need to set the video resolution and the monitor account to their maximum values. H.264, the most commonly used codec in the world, was designed specifically to support entertainment content and is known for its use in encoding Blu-ray movies. Chris Halstead co-authored the original version of this white paper. Use NVIDIA Tesla or newer GPUs.

It may be a good idea to completely uninstall VMware Tools and re-install. Set up the VM with general settings, as follows, and then further configure according to the type of graphics acceleration you are using. EncoderNvidiaHEVCEnabled Enables or turns off support for offloading HEVC encoding to NVIDIA GPUs installed in the ESXi hosts. More than 8 virtual CPUs might be required to support the most demanding use cases, especially video gaming, even with NVIDIA hardware GPUs. Broad client support, including Windows, Linux, Mac, Android, iOS, Chrome, and web (HTML Access) clients. The range is 136, where 1 is the highest quality. The following table documents the key codec and transport settings. Go to https://my.vmware.com/web/vmware/downloads. On the client, this means near universal H.264 GPU decode support, because nearly all devices with graphics cards manufactured since 2013 have hardware H.264 decode support, including cell phones and most thin clients. The former option allows Blast Extreme to burst and use more bandwidth when necessary, while the latter attempts to more strictly control it. The following table provides guidance on which codecs to use for various types of applications. The next component to optimize is the Windows operating system. However, this example can be achieved by disabling support for the H.264 codecs competing options: JPG/PNG and HEVC. Set up an RDSH server VM and install applications to be remoted to end users. Because WANs involve long-haul circuits or even satellite connections, they also impose latency (delay), extending how long it takes packets to travel from sender to receiver. VMware recommends use of Network QoS to prioritize display protocol network traffic, not just on constrained WAN circuits, but even on the LAN as well. If the testing in your environment is not successful, use JPG/PNG. Highlight the Security Server, then click the menu named More Commands and click Prepare for Upgrade or Reinstallation. The connection travels from the client to a Unified Access Gateway virtual appliance on TCP port 443, and then from the Unified Access Gateway to the Connection Server on TCP port 443. 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 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 formats employ compression to reduce the size of the content before it is transferred across the network. Watch conversations with VMware experts on top-of-mind issues. High Efficiency Video Coding, or HEVC for short, is also known as H.265 and is the industry successor to H.264. Yes: Select Allow High Efficiency Video Coding and Allow High Dynamic Range Decoding (HDR). The Blast Codec will continue to evolve. 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. Same applications as for the Blast Codec and the H.264 with HCA codec. 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. MinBandwidthKbps The minimum bandwidth used by all services, in kilobits per second. Display resource-intensive multimedia content in a window instead of full screen. It also causes some screen content to letterbox, which may impair user experience. only limits the bandwidth used to transfer the screen contents. 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. UdpEnabled Enables or turns off support for the UDP transport protocol. Enable build-to-lossless mode if supporting a use case such as non-diagnostic medical imaging, which requires the display to be transferred without loss of quality. Welcome to VMware Digital Workspace Tech Zone, your fastest path to understanding, evaluating, and deploying VMware End User Computing products. Display protocols have similar performance characteristics. Depending on the environment and design requirements, these external URLs can be configured in several different ways: Using multiple ports on a single address (Port Address Translation) 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. Demanding graphical applications commonly require more than two virtual CPUs, even with hardware GPU support. . This means the encoder preserves all of the information related to color instead of sacrificing some to increase codec efficiency. TCP port 32111 is then used between the Unified Access Gateway and agent. Once infrastructure resources and capacity have been verified, and the desktops and servers have been optimized, the performance of the display protocol can be tuned as necessary. Open "Device Manager" Right click on the VMware Display adapter and open "Properties" On the "Driver" tab, select "Uninstall" The 4:2:0 sample rate can result in color washout as well as text or image fuzziness when using some applications (for example, CAD) or some color combinations. Encoder Switch: JPG/PNG and H.264 with HCA. : NVIDIA GPUs will also offload H.264 and HEVC encoding. Explore the latest VMware tools designed to get your end-user computing environment running smoothly and efficiently. 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.
