Encoder Switch: JPG/PNG and H.264 with HCA. The descriptions mention various remote experience features. Actual results will depend on the application workloads and usage patterns. In the following screenshot, the Horizon Performance Tracker is reporting that the Blast session is using UDP and the NVIDIA HEVC codec. Do not forget the incoming Internet circuits. The Horizon Performance Tracker does not currently indicate HCA mode when NVIDIA encoding is used. VMware Blast Extreme Optimization Guide | VMware Use our product forums to engage with the community. Used together, the JPG/PNG codec is ideally suited for typical Windows and Linux applications, including Microsoft Office. But when rapidly changing screen content such as streaming video is detected, Blast Extreme automatically switches to multimedia optimized H.264. 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. Real-Time Audio-Video (RTAV) for Horizon View - VMware End-User This guide provides a technical description of the Blast Extreme display protocol, including its benefits, limitations, and deployment options, for administrators who are considering using Blast Extreme in their organization today. Internal testing resulted In a 12 percent bandwidth savings by doubling the size of both caches to 512 MB. Flexibility with regard to configuration methods, which include using Windows Group Policy or Horizon Smart Policies included with, Option to simplify setup, including opening only one port (TCP 443) on front-end firewalls when, AES (Advanced Encryption Standard) encryption. This is due to the much higher graphical quality this hardware-enabled configuration provides. Blast Extreme is a next-generation display protocol, developed by VMware. 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. For information about configuring this setting, see the guides Setting Up Virtual Desktops in Horizon, Setting Up Published Desktops and Applications in Horizon, and Administering Cloud Pod Architecture in Horizon, available from the VMware Horizon Documentation site. These formats employ compression to reduce the size of the content before it is transferred across the network. Screen 0/1 @ Resolution: 3840 x 2160. This Continued Yes: Select Allow H.264 Decoding. 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. 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. Troubleshooting Intermittent Blast Connection Issues in - VMware There is something for every experience level. 2 enabled client to server only If multimedia redirection (MMR) is enabled, this traffic uses TCP port 443 from the client to the Horizon Tunnel on the Unified Access Gateway. I'm sure this feature looked awesome on paper. The Blast Codec should be evaluated for use whenever network bandwidth or display protocol CPU utilization is a primary concern. Test the new Blast Codec. The Horizon Clients can use either IP version 4 or 6. The settings are configured in the Windows Registry of the Windows virtual and physical desktops and Microsoft RDSH servers. For more information see Configuring HTML5 Multimedia Redirectionin Configuring Remote Desktop Features in Horizon 7. 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. For external connections, Blast Extreme can use the security certificate on the Unified Access Gateway appliance. Figure 4: External Connection from Client to Agent Through the Unified Access Gateway. VMware Blast performance and end-user experience acceleration Blast is now the new default. Blast Extreme is included with VMware Horizon, the latest generation of VMware desktop virtualization and remote application-delivery software. JPG/PNG can also be configured to use build-to-lossless mode. Blast Extreme can also use the certificate thumbprint of the Blast Secure Gateway or virtual desktop. EncoderNvidiaHEVCEnabled Enables or turns off support for offloading HEVC encoding to NVIDIA GPUs installed in the ESXi hosts. When client-drive redirection (CDR) is enabled by the administrator, this traffic goes through the Horizon Tunnel on the Unified Access Gateway appliance. This is typically achieved using a Differentiated Services Code Point (DSCP) marking of AF41. VMware Blast Extreme uses the H.264 video encoding standard which any modern mobile device can handle in its GPU, rather than CPU. Yes: Select Allow High Efficiency Video Coding. If the testing in your environment is not successful, use JPG/PNG. Use of a solid color with no image or pattern is recommended. Learn how to architect the right security solutions for your business needs. EncoderBuildToPNG Enables or turns off build-to-lossless mode for the JPG/PNG codec. 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. Here's a screen shot of the codec settings from the Horizon client: If you uncheck the option, "Allow H.264 decoding," you'll fall back to JPG/PNG and Performance Tracker will report, "adaptive", as the encoder. A monitor at 4K resolution requires up to six times the bandwidth for the same application workload as 1080p. On the server side, H.264 encoding can be offloaded to NVIDIA Tesla GPUs, freeing the costly CPUs in. Create desktop pools, application pools, or both. The following settings are specifically helpful for handling low-bandwidth conditions: Note that these minimum and maximum bandwidth settings are best effort, not hard limits. However, this example can be achieved by disabling support for the H.264 codecs competing options: JPG/PNG and HEVC. Another important aspect to consider is the size of the monitor (or monitors) to be used, and their screen resolutions. blast-worker-sessionid1.log . The following registry settings have been determined through extensive testing to provide the biggest impact on system resources and user experience. If the testing is not successful, use JPG/PNG. If users experience any of these issues, HCA can be enabled to improve quality while preserving H.264s multimedia efficiency. Instructions for configuring all of the Blast Extreme codec options are provided in the next chapter, How to Configure Blast Extreme. Workspace ONE Access, formerly known as Identity Manager, is a powerful tool. Display protocols have similar performance characteristics. Let's set this to "Enabled" and set it to 60.

EncoderHEVCEnabled Enables or turns off support for the HEVC codec (H.265). While most of our environment is running PCoIP, we have also tested with BLAST. The next section describes the workflow of connections made between the client and agent components. :\ProgramData\VMware\VMware Blast\. Find assets to help you develop an adoption strategy that engages employees through careful messaging, education, and promotion. If users are permitted by the pool configuration to select a display protocol, Blast Extreme must be selected for each connections properties using the Horizon Client. VNCRegionEncoder_Create: region encoder BlastCodec. The VMware Blast service ( VMBlastS.exe) manages user sessions, proxies incoming TCP connections, and prepares the Blast Worker process. These were typically not sized to handle organizations rapidly shifting their workforces to work-from-home deployments. Same applications as for the Blast Codec and the H.264 with HCA codec. Limiting the resolution of employees monitors also greatly reduces Internet circuit bandwidth utilization. If you use a Unified Access Gateway virtual appliance for connections from outside the corporate network, by default the connection uses TCP port 8443 and optionally UDP port 8443. Information on how to enable build-to-lossless mode is covered in the next chapter, How to Configure Blast Extreme. Yes: Select Allow H.264 Decoding, and select Allow High Color Accuracy. EUC Solutions Exchange on VMware CODE is the best place to find and share snippets. For external connections: Unified Access Gateway 2.9 or later. The Blast Worker process determines whether UDP is enabled on the agent and allowed on the client. This ensures that all systems deployed from these templates are configured properly for Blast Extreme. Horizon is a complete solution that delivers, manages, and protects virtual desktops, RDSH-published desktops, and applications across devices and locations. Figure 3: Tunneled Connection from Client to Agent Through the Connection Server. This means that display content encoded and compressed using PNG alone can be restored to match the quality of the original content. If the file does not exist, it will create it with the blast settings already enabled. The fewer packets the display protocol has to transfer across the network, the fewer that will be affected by high latency. For more information, see Configuring HTML5 Multimedia Redirection in Configuring Remote Desktop Features in Horizon 7. 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.

HTML5 multimedia redirection transfers this screen content to the client as HTML5 code instead of far less efficient display protocol traffic. Workspace ONE Access, formerly known as Identity Manager, is a powerful tool. The VMware Blast ADMX template file ( vdm_blast.admx) contains policy settings for the VMware Blast display protocol. You can configure group policy settings that control the behavior of Real-Time Audio-Video (RTAV) on your remote desktops. If Sound Card is not available in the Settings pane, click Add Device > Sound Card, then click Add. The range is 136, where 1 is the highest quality. It is possible to configure the Blast External URL on the Unified Access Gateway appliance to use port sharing on TCP port 443 so that no additional ports need be opened on the front-end firewall. 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. VMware Blast detects the presence of a vGPU system and applies higher quality default settings. Customize your Workspace ONE and Horizon adoption communications using our templates as a starting point. Question: 1. only limits the bandwidth used to transfer the screen contents. For mixed workloads, use the encoder switch to dynamically switch between the new Blast Codec or JPG/PNG and H.264 codecs. A codec is used to encode and decode the screen content transferred by Blast Extreme. For Linux desktops: Horizon for Linux version 7.5 or later is required; Horizon for Linux version 7.10 or later is recommended. It is better to leverage HTML5 multimedia redirection to optimize such use cases. When client-drive redirection (CDR) is enabled by the administrator, by default, the traffic is side-channeled on the Blast Extreme channel. Fortunately, Blast Extreme supports the H.264 codec for precisely this type of content. This configuration is ideal for digital photography, design, and video production but requires an NVIDIA hardware GPU to support HEVC. 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. EncoderH264Enabled Enables or turns off support for H.264. Connection Server 7.1 or later is required; Connection Server 7.10 or later is recommended. If the end user can be interrupted, or if you are performing configuration testing, the easiest way to see the running session configuration is to use the Horizon Performance Tracker if it is installed. Control size of VMware Horizon View Blast logs For details about editing View Connection Server settings and security server settings, see the VMware Horizon View Administration documentation. The very latest in NVIDIA's lineup of GPUs, both these cards are . Graeme Gordon is a Senior Staff End-User-Computing Architect, EUC Technical Marketing, VMware. The App Volume Manager is a console for managing configuration, creation of AppStacks, and assignment of AppStacks and writable volumes. In testing this has been shown to decrease the amount of network bandwidth used by Blast Extreme. To observe this in action we can control the codec selection using the VMware Blast settings on the Horizon client. It also causes some screen content to letterbox, which may impair user experience. In this mode, under typical application conditions, Blast Extreme uses the Blast Codec or JPG/PNG codec, both of which are optimized for text and still image quality. 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. Horizon Client, on the client device, connects to a Connection Server on TCP port 443 for authentication and to request a desktop or application. High Efficiency Video Coding (HEVC) HTML5 multimedia redirection transfers this screen content to the client as HTML5 code instead of far less efficient display protocol traffic. (maximum display bandwidth) to the maximum desired bandwidth utilization per user. Therefore, it is imperative to start by verifying that all components are sized properly and have sufficient resources and available capacity. A TCP WebSocket connection is made on port 22443 between the client and the virtual desktop or RDSH server. Yes: Deselect all codecs and codec options (uncheck: H.264, Allow High Color Accuracy, and Allow High Efficiency Video Coding). The following tuning options are recommended to increase display protocol quality for all use cases and applications. In this file, add the single line: RemoteDisplay.allowClientBlastCodec = TRUE. You are about to be redirected to the central VMware login page. Highlight the Security Server, then click the menu named More Commands and click Prepare for Upgrade or Reinstallation. 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 is great for users that use their own devices with all kinds of displays and DPI settings and such. Although it has more of an impact on multimedia and video gaming, experiment with different values, up to the maximum of. In this mode, the codec is able to support applications that require the display protocol to be lossless, ensuring nothing is lost in transmission. Intelligence to determine and accommodate varying network conditions. 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. The Blast Codec was designed to be the ideal codec for these types of applications. Consider using the HEVC codec. Codec settings can also be set in the registry of the templates used to deploy pools of desktops and farms of RDSH servers. 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. Click the View All button for the full list. 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. Same applications that are ideal for H.264 while offloading the encoding from the ESXi host CPUs to an NVIDIA GPU. Be certain to test key applications and multimedia content before widespread deployment. They are designed to have something for people of every experience level. Use HTML5 multimedia redirection if resource-intensive web-browser-based content such as YouTube or eLearning streaming video must be supported. 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. NVIDIA Encoded H.264(H.264 Offloaded to GPU). 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.
