These efficient purpose-built thin clients offer ultrafast access to applications, files, and network resources within Virtual Desktop Infrastructure (VDI) environments. The following diagram shows the ports used for an internal connection, and the list that follows describes the order in which the connections are made. NVIDIA Encoded H.264 (H.264 offloaded to GPU), NVIDIA Encoded H.264 (H.264 offloaded to GPU) with HCA. Type: REG_SZ. Be certain to test key applications and multimedia content before widespread deployment. One of the easiest methods is to use the Windows Group Policy template provided with each release of VMware Horizon. Activity Paths are guided and curated learning paths through modules and activities that help you cover the most content in the shortest amount of time. Explore the latest VMware tools designed to get your end-user computing environment running smoothly and efficiently. Keep in mind, however, that Blast Extreme will always resort to using more bandwidth, if necessary, to prevent the session from crashing. 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. The Connection Server returns the connection information for the virtual desktop or RDSH server to the client. Optimize the desktops and RDSH servers using the VMware Operating System Optimization Tool. Information on how to enable build-to-lossless mode is covered in the next chapter, How to Configure Blast Extreme. 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). 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. 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 settings are configured in the Windows Registry of the Windows virtual and physical desktops and Microsoft RDSH servers. Using articles, videos, and labs, this activity path provides the fastest way to learn Workspace ONE! Although this results in a similar reduction in the network bandwidth required, it uses substantially more CPU processing power to encode and decode. Another key Blast Extreme innovation is the encoder switch. 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, installed on the client device, connects to a Connection Server on TCP port 443 for authentication and to request a desktop or application. NVIDIA Encoded H.264 Testing has shown this enables smooth 4K video playback without need for hardware GPUs. Learn how to architect the right security solutions for your business needs. MinBandwidthKbp and MaxBandwidthKbps also impact all services, including audio and file transfer, while MaxBandwidthKbpsPerMegaPixelSlope only limits the bandwidth used to transfer the screen contents. 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. VMware Blast Extreme uses the H.264 video encoding standard which any modern mobile device can handle in its GPU, rather than CPU. The connection workflow descriptions in this section also include information about the configurable components of Blast Extreme and the various Blast Extreme services and processes that are built into the virtual desktop agent. Horizon Client, on the client device, connects to a Connection Server on TCP port 443 for authentication and to request a desktop or application. Find all of TechZone's available downloadable content here. Instructions for configuring all of the Blast Extreme codec options are provided in the next chapter, How to Configure Blast Extreme. See, Worksheet for Creating an Instant-Clone Desktop Pool, You can also configure the remote display protocol at the RDSH server farm level. Log File Locations for Client and Agent Components The former option allows Blast Extreme to burst and use more bandwidth when necessary, while the latter attempts to more strictly control it. 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. Computer Configuration -> Policies -> Administrative . To observe this in action we can control the codec selection using the VMware Blast settings on the Horizon client. Highlight the Security Server, then click the menu named More Commands and click Prepare for Upgrade or Reinstallation. 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. 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. It also causes some screen content to letterbox, which may impair user experience. Using articles, videos and labs, this activity path provides the fastest way to learn Workspace ONE! Set, Turn off audio unless absolutely required. When client-drive redirection (CDR) is enabled by the administrator, by default, the traffic is side-channeled on the Blast Extreme channel. EncoderNvidiaHEVCEnabled Enables or turns off support for offloading HEVC encoding 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. TCP port 32111 is then used between the Unified Access Gateway and agent. Visit these other VMware sites for additional resources and content. The Blast Codec will continue to evolve. 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. The descriptions mention various remote experience features. High Efficiency Video Coding (HEVC). , which uniformly limits the bandwidth of all Blast Extreme services, can also be used to support more difficult network conditions. Applications and use-cases that require higher quality typically have demanding graphical requirements that can only be supported by hardware GPUs. Screen 0/1 @ Resolution: 3840 x 2160. This means that display content encoded and compressed using PNG alone can be restored to match the quality of the original content. 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. 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. VNCRegionEncoder_Create: region encoder h264 4:2:0. 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. : NVIDIA GPUs will also offload H.264 and HEVC encoding. Fortunately, VMware has developed a free tool to optimize Windows desktops and servers. All TCP and UDP connections use TLS to encrypt communication. It also tells whether a GPU is required on the client or server. 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. If UDP is not enabled or is blocked, the initial TCP connection (Step 3) is used instead. These pages help you understand the breadth of our most popular products. Use UDP unless the traffic must pass through a UDP-hostile network device such as a TCP-based SSL VPN. Value: 1. 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. General Settings - VMware VMware vSAN is a software-based storage feature that is built into the ESXi hypervisor and integrated with vSphere; it pools disk space from multiple ESXi hosts and provisions it via smart policies, such as protection limits, thin provisioning and erasure coding. Connection Server 7.1 or later is required; Connection Server 7.10 or later is recommended. However, it is important to note that building-to-lossless increases session bandwidth utilization because more display information is sent across the network. If users are experiencing poor text or image clarity in certain applications with H.264 alone, Blast Extreme can be configured to use High Color Accuracy (HCA). UdpEnabled Enables or turns off support for the UDP transport protocol. 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. 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. Navigate the sophisticated world of Unified Access Gateway (UAG) for Workspace ONE and Horizon 8. 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. TLS version and encryption defaults are routinely updated to reflect current best practices. However, in testing it has been determined that only Intel GPUs support OpenGL applications in a remote session. 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. Figure 3: Group Policy Settings for Blast Extreme. All three howeverNVIDIA, AMD, and Intelare able to support Microsoft DirectX. But when rapidly changing screen content such as streaming video is detected, Blast Extreme automatically switches to multimedia optimized H.264. How to troubleshoot a VMware Horizon black screen For external connections: Unified Access Gateway 2.9 or later. 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. A key design principle with VMware Blast Extreme is to offload graphics processing from the CPU, which reduces the power consumption for accessing a desktop. Join the community by engaging in forums, events, and our premier community programs. Monitors with higher screen resolutions, and use cases with multiple monitors, require more system resources, especially CPU and network bandwidth. This guide provides detailed information on how to configure and optimize Blast Extreme for these situations.

If desired, the traffic between Horizon Client and Horizon Agent can be configured to use a separate port (TCP 9427). In the client VMware Blast settings, Allow High Efficiency Video Decoding (HEVC) and Allow High Dynamic Range Decoding (HDR) needs to be turned on. Let us help you become the hero of your department. Blast Extreme is included with VMware Horizon, the latest generation of VMware desktop virtualization and remote application-delivery software. In testing with a single 4K display, viewing a typical YouTube video in standard windowed mode used 53 percent less bandwidth and 23 percent less virtual desktop CPU than watching the same video full-screen. (Requires NVIDIA GPU), VNCRegionEncoder_Create: region encoder NVIDIA NvEnc HEVC. Watch conversations with VMware experts on top-of-mind issues. Applications that require higher graphical quality with improved color range and contrast, such as digital photography. If you are using Horizon Client for macOS 5.0 or later, this Horizon Collector functionality is included in Horizon Client. The Blast Worker process ( VMBlastW.exe) captures the screen and handles everything within the session. The encoder switch dynamically switches between either the JPG/PNG codec or the Blast Codec, and H.264, depending on the screen content type. TCP port 9427 is then used from the Unified Access Gateway to the agent. EncoderH264Enabled Enables or turns off support for H.264. DecoderImageCacheSizeKB Introduced in Horizon 8 (2111).Set on the client. Navigate to Virtual Machine > Settings (Fusion) or VM > Settings (Workstation). 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. 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. A stated goal in the VMware Horizon documentation 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." VMware notes that "some use cases and situations require additional tuning, especially for wide area networks . SwitchEnc: 1 Screen 1 switching to h264 4:2:0 encoder. 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. And if Blast Extreme encounters problems making its initial connection over UDP, it will automatically switch and use TCP for the session instead. 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. VMware Blast Policy Settings (the lowest currently supported setting). There is something for every experience level. Expanded the guidance on how to enable different codecs and verify the running configuration. In the following screenshot, the Horizon Performance Tracker is reporting that the Blast session is using UDP and the NVIDIA HEVC codec. VMware Horizon, Blast Extreme and NVIDIA virtual GPU - VMBlog For details about editing View Connection Server settings and security server settings, see the VMware Horizon View Administration documentation. Most settings make the option available to be used (set to 1) or not (set to 0). (maximum display bandwidth) to the maximum desired bandwidth utilization per user. Horizon Client version 5.2 only also requires a special configuration file on the client (see the note following this table). If users experience any of these issues, HCA can be enabled to improve quality while preserving H.264s multimedia efficiency. But it can also be used to support graphically intensive applications by leveraging the desktops physical GPU. 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. 1 enable upload and download 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. New in Horizon 8 (2106): HEVC with High Dynamic Range (HDR) Encoding. Feature parity with the VMware PCoIP display protocol. Note: Despite the presence of a physical GPU, Blast Extreme with physical desktops is not able to offload H.264, H.264 with High Color Accuracy, or High Efficiency Video Coding (HEVC) encoding, even with NVIDIA GPUs. 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. The default setting of 6200 is geared towards efficiently supporting a medium-quality use case. Remember that you are separating the user and their keyboard, monitor, and mouse from the system they are actually using. Navigate the sophisticated world of Unified Access Gateway (UAG) for Workspace ONE and Horizon 8. The Horizon Performance Tracker is an option that can be selected during the Horizon Agent installation on the virtual desktop, physical desktop, or RDSH server. 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 Click the View All button for the full list. By default, the traffic is then side-channeled on the Blast Extreme channel to the agent. Update for VMware Horizon 7 version 7.10. Keep in mind, however, that Blast Extreme will always resort to using more bandwidth, if necessary, to prevent the session from crashing. Webcam support in VMware Horizon View is a feature that has frequently been requested. WANs typically have just a fraction of the bandwidth that is available on local area networks (LANs). 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. Encoder Switch: JPG/PNG and H.264 with HCA. Begin your journey leveraging cloud-based services for desktop environments. Fix the network if packet loss is greater than 5 percent. Use our product forums to engage with the community. Use TCP if latency is greater than 250 milliseconds. Limiting the resolution of employees monitors also greatly reduces Internet circuit bandwidth utilization. Troubleshooting VMware Horizon View Blast Secure Gateway Service Initiation Issues (54145) - This article walks through steps to increase logging to get precise . NVIDIA Encoded H.264(H.264 Offloaded to GPU). Most configuration settings can be made directly in the Windows Registry of each virtual and physical desktop and RDSH server using your preferred tool for making such registry changes. If USB redirection is enabled, this traffic uses TCP 32111 between the client and agent. 2 enabled client to server only Use a single monitor with the lowest screen resolution supported by the use case. Clients 5.3 and later do not. In other words, the settings do not directly enable the feature, such as forcing all connections to use H.264. 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). Using VMware's Horizon Performance Tracker For Rudimentary Blast I ended up writing a logon script to solve the problem until VMware fixes it. Testing has shown this reduces the bandwidth required to support such content by up to 80 percent. This is simply due to the larger number of pixels that must be supported at higher resolutions. Windows display scale to vmware display scaling Same applications as for the Blast Codec and the H.264 with HCA codec. Get all the Tech Zone demos in one place. This will force H.264 to start at higher quality and prevent it from expending bandwidth to send initial low-quality screens. Horizon Client, on the client device, authenticates and requests a desktop or application. This configuration is ideal for digital photography, design, and video production but requires an NVIDIA hardware GPU to support HEVC. Reducing network bandwidth is key to enabling support for all adverse network conditions. However, it is a new and rapidly evolving codec. However, some use cases and situations require additional tuning, especially for wide area networks (WANs). Explore how VMware can help solve an IT team's most pressing digital workspace challenges. The port used by the Blast Secure Gateway on the Unified Access Gateway can be customized (for example, it can use TCP 443). If i enable USB Redirection for the Headset, i can choose 48.000 Hz.
