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. If the administrator has enabled additional remote experience features such as USB redirection or client-drive redirection (CDR), the administrator can choose whether traffic for these features will be carried on virtual channels within the Blast session or on separate dedicated connections. 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. Added recommendations for supporting work-at-home and home-office-to-cloud use cases. 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. HDR also requires Horizon 8 (210) or later with Horizon Agent build 2106-8.3.0-18287218 or later and Horizon Client build 2106-8.3.0-18287501 or later. Horizon Client 4.8 or later is required; Horizon Client 5.2 or later is recommended. Chris Halstead co-authored the original version of this white paper. Do not starve the virtual desktops and RDSH servers of resources. Note: Different types of client devices support different features of Blast Extreme. 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. While most of the Blast Extreme settings are included in the ADMX template, some are not, including those related to the Blast Codec and encoder switch. Testing has shown this reduces the bandwidth required to support such content by up to 80 percent. This means that display content encoded and compressed using PNG alone can be restored to match the quality of the original content. Here you can create an account, or login with your existing Customer Connect / Partner Connect / Customer Connect ID. 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. 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. : NVIDIA GPUs will also offload H.264 and HEVC encoding. Note: At this point, the VMware Blast service on the agent side (Horizon Agent on the virtual desktop or RDSH server) proxies the incoming TCP connection. Horizon Client 5.2 requires a special client setting. VNCRegionEncoder_Create: region encoder switch. 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. Welcome to VMware Digital Workspace Tech Zone, your fastest path to understanding, evaluating, and deploying VMware End User Computing products. Adjustable Encoder Image Cache Size and Decoder Image Cache Size settings. For further information about configuring Blast Extreme to use DSCP marking reference, see. If UDP is not enabled or is blocked, the initial TCP connection (Step 3) is used instead. Why it is only showing this low settings? The port used by the Blast Secure Gateway on the Unified Access Gateway can be customized (for example, it can use TCP 443). NVIDIA H.264 with HighColorAccuracy EncoderH264YUV444 Enables or turns off support for High Color Accuracy for H.264. These settings apply to HTML Access and all Horizon Client platforms. Codec settings can also be set in the registry of the templates used to deploy pools of desktops and farms of RDSH servers. and includes optimization templates for both Windows desktop and server operating systems. The connection continues from the Unified Access Gateway to UDP port 22443 on the agent. There is something for every experience level. The Blast Codec will continue to evolve. 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. Let us help you learn how to use it. Set, Turn off audio unless absolutely required. Webcam support in VMware Horizon View is a feature that has frequently been requested. For more information, see "VMware Blast Policy Settings" in the Horizon Remote Desktop Features and GPOs document. Yes: Deselect all codecs and codec options (uncheck: H.264, Allow High Color Accuracy, and Allow High Efficiency Video Coding). One of the easiest methods is to use the Windows Group Policy template provided with each release of VMware Horizon. 2 enable file upload only If you have a GPU to offload H. 264 and the available bandwidth, you can change this setting to reduce the . However, in testing it has been determined that only Intel GPUs support OpenGL applications in a remote session. The range is 136, where 1 is the highest quality. , which uniformly limits the bandwidth of all Blast Extreme services, can also be used to support more difficult network conditions. (the lowest currently supported setting). Type: REG_SZ. MaxBandwidthKbps The maximum bandwidth used by all services (display, keyboard and mouse, audio, file transfer, clipboard, and so on), in kilobits per second. Still, when logged into a virtual machine, there is no improvement to the quality of the picture when run on a Thin Client. A certificate thumbprint is a cryptographic hash of a certificate. Start here to understand the basics of the award-winning product suite. Expanded the guidance on how to enable different codecs and verify the running configuration. Blast Extreme will always resort to using more bandwidth, if necessary, to prevent the session from crashing. Refer to Using Horizon to Access Physical Windows Machines for more information about using Blast Extreme with physical desktops. Introduced in Horizon 8 (2106): Enable support for High Dynamic Range (HDR) color. SwitchEnc: 1 Screen 1 switching to h264 4:2:0 encoder. Note that this increases bandwidth and virtual desktop CPU utilization. Each setting is a string value (REG_SZ). Deselect all other codecs and codec options. However, it is a new and rapidly evolving codec. Specializing in IT architecture on every scale, Mark has designed hundreds of successful solutions for organizations of all sizes and verticals. The following tuning options are recommended to increase display protocol quality for all use cases and applications. A TCP WebSocket connection is made from the client to the Blast Secure Gateway on port 8443, and then from the Blast Secure Gateway to the virtual desktop or RDSH server on port 22443. All three howeverNVIDIA, AMD, and Intelare able to support Microsoft DirectX. For Linux desktops: Horizon for Linux version 7.5 or later is required; Horizon for Linux version 7.10 or later is recommended. VNCSERVER-WIN32: ***Setting topology completed by Nvidia Display***. Therefore, Blast Extreme can typically be left using its default setting of UDP unless the traffic must pass through a UDP-hostile network device such as a TCP-based SSL VPN. 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. With Horizon 7 version 7.12, support for using Blast Extreme with physical desktop machines running Windows 10 versions 1903 and later was added. Be certain to test key applications and multimedia content before widespread deployment. Blast Extreme must be on TCP 443 only (as described previously for port sharing). 8 Use View Administrator to configure the Blast External URL setting to use for the Blast Secure Gateway on the applicable View Connection Server instances and security servers. 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. With zero attack surface, unpublished API, and encrypted data Wyse ThinOS is virus and malware resistant. 1 In VMware Horizon, when using PCoIP Secure Gateway on the Connection Server or Security Server. They are designed to have something for people of every experience level. General Settings The following table describes the general settings in the Horizon Client Configuration ADMX template file. It also causes some screen content to letterbox, which may impair user experience. Yes: Select Allow H.264 on the client. 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. EncoderH264Enabled Enables or turns off support for H.264. Find assets to help you develop an adoption strategy that engages employees through careful messaging, education, and promotion. Fortunately, Blast Extreme can be tuned to handle all of these situations. Be sure to also leverage HTML5 multimedia redirection if browser-based HTML5 content must be supported. In the client VMware Blast settings, Allow High Efficiency Video Decoding (HEVC) and Allow High Dynamic Range Decoding (HDR) needs to be turned on. If USB redirection is enabled, this traffic, this traffic uses TCP port 443 from the client to the Horizon Tunnel on the Unified Access Gateway. Display communication protocols provide end users with a graphical interface to a remote desktop or published application. Note: To enable the new Blast Codec with Horizon Client 5.2, create a file named: config.ini in %appdata%/Vmware in each users profile on their virtual desktop or shared RDSH server. 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. The following registry settings have been determined through extensive testing to provide the biggest impact on system resources and user experience. Applications requiring lossless reproduction of original screen content such as non-diagnostic medical imaging. USB redirection traffic can also be side-channeled in the Blast Extreme port between the Unified Access Gateway and agent. These pages help you understand the breadth of our most popular products. JPG/PNG and H.264 with HCA. VNCRegionEncoder_Create: region encoder BlastCodec. It is important to recognize, however, that no display protocol can provide a perfect LAN experience over typical WANs. However, compared to other codecs, H.264 requires more processing power to perform its encoding and decoding operations. When you have created the registry key, re-initiate the connection to your VDI machine. [VVCSessionManager] BlastSocketDataSockActivatedCb: Data Connection:UDP, [VVCSessionManager] BlastSocketDataSockActivatedCb: Data Connection:TCP. Although this strategy makes for reliable delivery, the process adds overhead. Consider using the HEVC codec. For other browsers, the JPG/PNG codec is used. ) Added new observations on the impact of increasing screen resolution on key system resources. Blast Extreme includes the following security features to support Horizon: Display protocols must be able to efficiently provide the best user experience for various types of screen content, including text, still images, streaming video, 3D rendering, and audio. Settings made directly in the registry are dynamic and take effect immediately, whereas those requiring a client setting will take effect only after the client disconnects and reconnects to a live session. 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) Monitor for high CPU Ready times (which are evidence of processor contention). Contains entries that tell you whether JPG/PNG or the H.264 coded is being used. Fortunately, Blast Extreme supports the H.264 codec for precisely this type of content. On the server side, H.264 encoding can be offloaded to NVIDIA Tesla GPUs, freeing the costly CPUs in. Note: Dynamic Environment Manager also provides optimization templates for Blast Extreme. The Blast Worker process ( VMBlastW.exe) captures the screen and handles everything within the session. 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. Use a single monitor with the lowest screen resolution supported by the use case. DecoderImageCacheSizeKB Introduced in Horizon 8 (2111).Set on the client. The VMware Blast service ( VMBlastS.exe) manages user sessions, proxies incoming TCP connections, and prepares the Blast Worker process. The encoder switch dynamically switches between either the JPG/PNG codec or the Blast Codec, and H.264, depending on the screen content type. The settings are configured in the Windows Registry of the Windows virtual and physical desktops and Microsoft RDSH servers. These were typically not sized to handle organizations rapidly shifting their workforces to work-from-home deployments. Yes: Select Allow H.264 Decoding. Learn how to architect the right security solutions for your business needs. There is a unified image quality configuration setting that controls the remoted display image quality level across all Blast encoders. No tuning for Network Latency: Low bandwidth / High latency Environments require additional tuning, Please see Tuning Blast Extreme for Wide Area Networks for details. Remember that you are separating the user and their keyboard, monitor, and mouse from the system they are actually using. Before starting to plan or trying to troubleshoot Horizon and Blast connections, it is important to understand how a VMware Horizon Client connects to a resource. captures the screen and handles everything within the session. Actual results will depend on the application workloads and usage patterns. Like HEVC, the encoding for H.264 and H.264 with HCA can be offloaded to NVIDIA GPUs installed in the ESXi hosts. Audio is also enabled, but is not currently being used. Screen 0/1 @ Resolution: 3840 x 2160. 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. Figure 3: Tunneled Connection from Client to Agent Through the Connection Server. Desktop and RDSH server sizing and optimization. This is also due to a limitation of desktop-class video drivers. Moving to the cloud? Desktop wallpaper unnecessarily expends both CPU resources to encode and network bandwidth to transfer.
