Fortunately, these can typically be supported with additional resources and special tuning. to identify the best quality at an acceptable level of bandwidth utilization. As its name implies, the JPG/PNG codec leverages two image formats, JPG and PNG, to encode and decode display content. Horizon is a complete solution that delivers, manages, and protects virtual desktops, RDSH-published desktops, and applications across devices and locations. 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. This connection is from the client to UDP port 8443 on the Unified Access Gateway. Another important aspect to consider is the size of the monitor (or monitors) to be used, and their screen resolutions. This tool takes a very high-level pass at turning off everything that only makes sense in physical server environments and tries to tune performance settings for VM environments. Developed for a variety of workloads, Blast is optimized for an ideal user experience and resource consumption. A consistent user experience across devices and locations while keeping corporate data compliant and securely stored in the data center. It is not supported in Horizon 7. The following table provides guidance on which codecs to use for various types of applications. In testing, TCP has been shown to handle high latency better than UDP. There is something for every experience level. The Horizon Performance Tracker does not currently indicate HCA mode when NVIDIA encoding is used. Ensure that ESXi hosts have sufficient resources, especially CPU. Learn how to architect the right security solutions for your business needs. EncoderSwitchEnabled Enables or turns off automatic switching between H.264 and JPG/PNG based on screen content. By default, Blast Extreme is capped at 30 frames per second (FPS). Be certain to test key applications and multimedia content before embarking on widespread deployment. and includes optimization templates for both Windows desktop and server operating systems. Navigate the sophisticated world of Unified Access Gateway (UAG) for Workspace ONE and Horizon 8. General Settings for Virtual Machines If multimedia redirection (MMR) is enabled, this traffic uses TCP port 9427 between the client and agent. Blast Extreme was carefully designed to provide an excellent out-of-the-box experience, with no additional configuration required in almost all cases. Added new observations on the impact of increasing screen resolution on key system resources. The goal is to configure QoS to prioritize Blast Extreme above general network traffic, but below the few applications that are even more sensitive to delay. The settings are configured in the Windows Registry of the Windows virtual and physical desktops and Microsoft RDSH servers. 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. Important: Many of the optimizations available to the other codecs have not yet been developed for the Blast Codec, including the ability to set custom image qualities. For mixed workloads, use the encoder switch to dynamically switch between the new Blast Codec or JPG/PNG and H.264 codecs. On the right, switch to the tab named Security Servers. Navigate to Virtual Machine > Settings (Fusion) or VM > Settings (Workstation). This not only provides a genuine hardware GPU to accelerate system and application graphics, it also frees the virtual CPUs for other tasks, helping to improve user experience and system scalability. H264maxQP The lowest quality that H.264 will start with before building the screen to higher quality. VNCRegionEncoder_Create: region encoder adaptive. Horizon Client, on the client device, authenticates and requests a desktop or application. Readers should also have a solid understanding of desktop and application virtualization, as well as a good working knowledge of networking and supporting infrastructure, covering topics such as Active Directory, Group Policy, and supporting technologies. Let us help you learn how to use it. However, it is important to note that building-to-lossless increases session bandwidth utilization because more display information is sent across the network. These formats employ compression to reduce the size of the content before it is transferred across the network. Blast Extreme can also use the certificate thumbprint of the Blast Secure Gateway or virtual desktop. The following table details the requirements for each codec. VNCSERVER-WIN32: Successfully changed the NV display. We have many more paths than are shown here. However, compared to other codecs, H.264 requires more processing power to perform its encoding and decoding operations. Remember that you are separating the user and their keyboard, monitor, and mouse from the system they are actually using. No tuning for Network Latency: Low bandwidth / High latency Environments require additional tuning, Please see Tuning Blast Extreme for Wide Area Networks for details. Fortunately, Blast Extreme supports the H.264 codec for precisely this type of content. Highlight the Security Server, then click the menu named More Commands and click Prepare for Upgrade or Reinstallation. The Blast Worker process determines whether UDP is enabled on the agent and allowed on the client. (maximum display bandwidth) to the maximum desired bandwidth utilization per user. Work with network partners and circuit providers to fix the network. Set, Use Blast Extreme clipboard settings to reduce or block using the clipboard. Use Adobe Flash redirection if extensive use of Adobe Flash must be supported. Deploy virtual desktops and RDSH servers on fast virtual disks (all-flash or flash-optimized). Although this strategy makes for reliable delivery, the process adds overhead. Many of the codec options and Blast Extreme settings can be controlled by administrators. Figure 3: Tunneled Connection from Client to Agent Through the Connection Server. For details about port requirements for connectivity between the various components and servers in a Horizon deployment, see Network Ports in VMware Horizon. HEVC provides up to 50 percent better compression with the same quality as H.264. Monitors with higher screen resolutions, and use cases with multiple monitors, require more system resources, especially CPU and network bandwidth. However, because H.265 requires substantially more processing power than H.264 to encode and decode, the ESXi hosts for desktops and server farms must have NVIDIA Tesla GPUs to offload encoding. The settings allow you to manage the maximum bandwidth that any one user can consume. JpegQualityHigh The highest quality that JPG/PNG will achieve. New in Horizon 8 (2106): HEVC with High Dynamic Range (HDR) Encoding. These pages help you understand the breadth of our most popular products. One of the easiest methods is to use the Windows Group Policy template provided with each release of VMware Horizon. When client-drive redirection (CDR) is enabled by the administrator, this traffic goes through the Horizon Tunnel on the Unified Access Gateway appliance. A Windows Registry value also needs to be set to 1 on the Client under HKLM\SOFTWARE\VMware, Inc.\Vmware VDM\Client\AllowClientHDR to enable HDR. Use NVIDIA GPUs. The App Volume Manager is a console for managing configuration, creation of AppStacks, and assignment of AppStacks and writable volumes. TCP 443 is used between the client and the Unified Access Gateway. H.264 applications that require higher color quality or that exhibit lack of clarity with H.264 alone. Figure 2: Codec Options Available in the Horizon Client. Therefore, it is imperative to start by verifying that all components are sized properly and have sufficient resources and available capacity. Lower power consumption means longer battery life. HEVC requires NVIDIA GPUs to be installed in the ESXi hosts to offload encoding. 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. If other optimizations are not working as expected, verify there are no settings in HKEY_CURRENT_USER. The running codec and codec options can also be identified by examining the latest entries in the Blast-Worker-SessionId<#>.log file, as detailed in the following table. 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. 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. EncoderBlastCodecEnabled Enables or turns off the Blast Codec. Optimize the desktops and RDSH servers using the VMware Operating System Optimization Tool. 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. DecoderImageCacheSizeKB Introduced in Horizon 8 (2111).Set on the client. Like HEVC, the encoding for H.264 and H.264 with HCA can be offloaded to NVIDIA GPUs installed in the ESXi hosts. The image formats used by these codecs employ compression to reduce the size of the content before it is transferred across the network. A Blast session is established between the client and agent (virtual desktop or RDSH server), using the TCP and, if available, UDP connection established through the Blast Secure Gateway. 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. Without QoS, there is nothing to prevent lower value network traffic from impairing the performance of time-sensitive applications including Voice over IP and virtual desktops supported by display protocols like Blast Extreme. Testing has shown this enables smooth 4K video playback without need for hardware GPUs. Moving to the cloud?

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. Added information about OpenGL and DirectX compatibility with hardware GPUs in remoted physical PCs. Here you can create an account, or login with your existing Customer Connect / Partner Connect / Customer Connect ID. Update for VMware Horizon 7 version 7.10. While the JPG algorithm attempts to remove only redundant data, in practice other data is lost as well. When client-drive redirection (CDR) is enabled by the administrator, by default, the traffic is side-channeled on the Blast Extreme channel. Problem is with second file, which is growing sometimes up to 15GB, then new files are created. There is a unified image quality configuration setting that controls the remoted display image quality level across all Blast encoders. 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. If you have a GPU to offload H. 264 and the available bandwidth, you can change this setting to reduce the . Information on how to enable build-to-lossless mode is covered in the next chapter, How to Configure Blast Extreme. However, some applications and use cases require higher quality. : Because port sharing incurs some performance overhead on Unified Access Gateway, port sharing is not the preferred configuration. After you apply the policy, the system stores the settings in the registry key HKLM\Software\Policies\VMware, Inc.\VMware Blast\config. Yes: Deselect all codecs and codec options (uncheck: H.264, Allow High Color Accuracy, and Allow High Efficiency Video Coding). Same applications that are ideal for H.264 while offloading the encoding from the ESXi host CPUs to an NVIDIA GPU. It also causes some streaming video to letterbox, which may impair user experience. Screen 0/1 @ Resolution: 3840 x 2160. Mark Ewert has been working in IT for over 25 years, with nearly two decades hands-on experience with VMware technologies. WANs typically have just a fraction of the bandwidth that is available on local area networks (LANs). Value: 1. In a typical environment, the admx policy files go into \\<domain name>\SYSVOL\<domain name>\Policies\PolicyDefinitions. Horizon is a complete solution that delivers, manages, and protects virtual desktops, RDSH-published desktops, and applications across devices and locations. Horizon Client 4.8 or later is required; Horizon Client 5.2 or later is recommended. If the testing is not successful, use JPG/PNG. 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. 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. 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. This is due to the much higher graphical quality this hardware-enabled configuration provides. Utilize this tool to get you part of the way there. 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. Note that HDR is an optional capability of HEVC (High Efficiency Video Coding, H.265) and requires an NVIDIA hardware GPU. Get introduced to our content types, tools, and capabilities. Blast Extreme is included with VMware Horizon, the latest generation of VMware desktop virtualization and remote application-delivery software. These settings apply to HTML Access and all Horizon Client platforms. Figure 4: Horizon Performance Tracker Reports Details of a Blast Extreme Session, NVIDIA Encoded H.264 with High Color Accuracy. Screen 0/1 @ Resolution: 3840 x 2160. Keep in mind, however, that Blast Extreme will always resort to using more bandwidth, if necessary, to prevent the session from crashing. The registry location to configure Blast Extreme is: HKEY_LOCAL_MACHINE\SOFTWARE\Vmware, Inc.\Vmware Blast\Config. The fourth Blast Extreme codec option is HEVC. The former option allows Blast Extreme to burst and use more bandwidth when necessary, while the latter attempts to more strictly control it. Used together, the JPG/PNG codec is ideally suited for typical Windows and Linux applications, including Microsoft Office. Use cases of this caliber nearly always require hardware GPUs to provide the necessary graphics capabilities and acceleration. 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. Screen 0/1 @ Resolution: 3840 x 2160, New in Horizon 8 (2106): HEVCwith High Dynamic Range (HDR) Encoding, VNCSERVER-WIN32: Enabled HDR on display \\.\DISPLAY9 You can increase the rate, up to 60 FPS, by using the Windows Registry setting. 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. A certificate thumbprint is a cryptographic hash of a certificate. Use UDP unless the traffic must pass through a UDP-hostile network device such as a TCP-based SSL VPN. Same applications as for the Blast Codec and the H.264 codec. 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. Go to https://my.vmware.com/web/vmware/downloads. The descriptions mention various remote experience features. This can result in H.264 being used for one display and JPG/PNG or the Blast Codec being used for another simultaneously. However, if the network also supports interactive video, Blast Extreme is often marked one-level lower with a DSCP marking of AF31. 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). This guide provides detailed information on how to configure and optimize Blast Extreme for these situations. H.264 will provide support for full-motion graphics, whereas the encoder switch will ensure that the most efficient codec is dynamically used for each screen based on screen content.
