VMware recommends using VMware Dynamic Environment Manager (formerly known as User Environment Manager). Blast Extreme was carefully designed to provide an excellent out-of-the-box experience, with no additional configuration required in almost all cases. Horizon Agent 7.5 or later is required; Horizon Agent 7.10 or later is recommended. Adjustable Encoder Image Cache Size and Decoder Image Cache Size settings. Get introduced to our content types, tools, and capabilities. and includes optimization templates for both Windows desktop and server operating systems. Use a single monitor with the lowest screen resolution supported by the use case. Fortunately, this processing can be offloaded from the CPU to graphics cards (GPU) in the device. For more information, see. 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. MaxBandwidthKbps The maximum bandwidth used by all services (display, keyboard and mouse, audio, file transfer, clipboard, and so on), in kilobits per second. SwitchEnc: 1 Screen 1 switching to h264 4:2:0 encoder. New in Horizon 8 (2106): HEVC with High Dynamic Range (HDR) Encoding. This configuration is ideal for digital photography, design and video production. The future successor to JPG/PNG, the Blast Codec provides a high-quality user experience while using significantly less CPU and network bandwidth required by other codecs. 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 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 Connection Server. Diagrams show which ports are used at which locations, and the numbered lists that follow the diagrams show what is happening at each connection. 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. Do not attempt to support high-quality use cases over a WAN or poorly functioning network. Introduced in Horizon 8 (2111) is the ability to adjust the size of the Blast codec cache. Desktop and RDSH server sizing and optimization. USB redirection traffic can also be side-channeled in the Blast Extreme port between the Unified Access Gateway and agent. Clients 5.3 and later do not. EncoderH264YUV444 Enables or turns off support for High Color Accuracy for H.264. Expanded the guidance on how to enable different codecs and verify the running configuration. The evaluation process has been initiated. The VMware Blast service ( VMBlastS.exe) manages user sessions, proxies incoming TCP connections, and prepares the Blast Worker process. Workspace ONE Access, formerly known as Identity Manager, is a powerful tool. Although it has more of an impact on multimedia and video gaming, experiment with different values, up to the maximum of. 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. EncoderMaxFPS The maximum frames per second that Blast Extreme will display. Get to know EUC vExperts from around the world. Consider using the HEVC codec. Highlight the Security Server, then click the menu named More Commands and click Prepare for Upgrade or Reinstallation. There is something for every experience level. Note: To open the dialog box for changing VM settings, in the vSphere Web Client, right-click the VM in the inventory, and select Edit Settings. The next component to optimize is the Windows operating system. Introduced in Horizon 8 (2106): Enable support for High Dynamic Range (HDR) color. Find all of TechZone's available downloadable content here. This ensures that all systems deployed from these templates are configured properly for Blast Extreme. Test the new Blast Codec. Deselect all other codecs and codec options. The range is 136, where 1 is the highest quality. It also causes some screen content to letterbox, which may impair user experience. 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. NVIDIA and AMD GPUs are not able to support OpenGL due to a limitation of their video drivers. EncoderBlastCodecEnabled Enables or turns off the Blast Codec. One of the easiest methods is to use the Windows Group Policy template provided with each release of VMware Horizon. They are designed to have something for people of every experience level. Get to know EUC vExperts from around the world. To set up the Horizon environment for Blast Extreme, administrators open various firewall ports and select Blast Extreme as the default display protocol or as a possible protocol choice for end users: Use the correct version of Horizon and related components: With Horizon 7 version 7.7, VMware introduced the ability to broker physical desktop machines running Windows 10 version 1803 and 1809 Enterprise Edition, via the Blast Extreme display protocol. Deselect all other codecs and codec options. The VMware Workspace ONE and Horizon Reference Architecture guide provides guidance for architecting Workspace ONE and Horizon deployments. TLS version and encryption defaults are routinely updated to reflect current best practices. TCP port 32111 is then used between the Unified Access Gateway and agent. 4 If using Blast Secure Gateway 5 Not using Blast Secure Gateway 6 Standard encoded RMI 7 RMI over SSL Because of its efficiency and excellent performance, UDP, which is the default transport protocol Blast Extreme uses, should not be changed, with two exceptions. Introduced in Horizon 8 (2106): Leverage High Efficiency Video Coding (HEVC) with High Dynamic Range (HDR) encoding to provide higher graphical quality with improved color range and contrast. 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. With the Horizon 2106 release, we also announced support for the NVIDIA Ampere A10 and A40 GPUs. 1 enable upload and download VMware has built a set of tools and resources to support you and your team as you build out an adoption strategy. H.264 applications that require higher color quality or that exhibit lack of clarity with H.264 alone. If desired, the traffic between the Unified Access Gateway and Horizon Agent can be configured to use a separate port (TCP 9427). Yes: Deselect all codecs and codec options (uncheck: H.264, Allow High Color Accuracy, and Allow High Efficiency Video Coding). 3 enabled server to client only. The descriptions mention various remote experience features. This means most should be considered medium- to high-speed WAN use cases. 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). However, some applications and use cases require higher quality. Screen 0/1 @ Resolution: 3840 x 2160. To collect logs on a Mac, you can use the. With Horizon 7 version 7.12, support for using Blast Extreme with physical desktop machines running Windows 10 versions 1903 and later was added. Note that HDR is an optional capability of HEVC (High Efficiency Video Coding, H.265) and requires an NVIDIA hardware GPU. Figure 3: Group Policy Settings for Blast Extreme. TCP port 9427 is then used from the Unified Access Gateway to the agent. 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. 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. It also causes some screen content to letterbox, which may impair user experience. Figure 4: External Connection from Client to Agent Through the Unified Access Gateway. Still, when logged into a virtual machine, there is no improvement to the quality of the picture when run on a Thin Client. Fortunately, these can typically be supported with additional resources and special tuning. In testing, UDP has been shown to handle packet loss better than TCP in most situations. Contains entries that tell you whether UDP or TCP is being used. Windows desktop and server operating systems are not designed for efficient virtualization. They are designed to have something for people of every experience level. 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. More information about the admin settings is provided in the next section of this chapter. 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. When client-drive redirection (CDR) is enabled by the administrator, by default, the traffic is side-channeled on the Blast Extreme channel. Explore the latest VMware tools designed to get your end-user computing environment running smoothly and efficiently. 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. This provides increased scalability and better performance, especially in CPU-constrained ESXi environments without NVIDIA GPUs. 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. The VMware Blast ADMX template file ( vdm_blast.admx) contains policy settings for the VMware Blast display protocol. Workspace ONE Access, formerly known as Identity Manager, is a powerful tool. 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. If other optimizations are not working as expected, verify there are no settings in HKEY_CURRENT_USER. Deselect all other codecs and codec options. Install VMware Horizon Client on end users' machines and have end users access their remote desktops and applications. TCP 443 is used between the client and the Unified Access Gateway. 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. If the UDP connection is successful, Blast assesses the networks condition to decide whether to use TCP or UDP for session traffic. Fortunately, Blast Extreme supports the H.264 codec for precisely this type of content. 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. For more information, see, Common Criteria Certification Report for VMware Horizon. Chris Halstead co-authored the original version of this white paper. In testing, viewing a YouTube video in a standard window instead of full-screen reduced bandwidth utilization by 53 percent. VMware Blast detects the presence of a vGPU system and applies higher quality default settings. Blast-Worker-SessionID#.txt. Navigate the sophisticated world of Unified Access Gateway (UAG) for Workspace ONE and Horizon 8. First introduced in Horizon 7.10, the Blast Codec is rapidly evolving but does not yet support all the optimizations and configuration options available to the other codecs. If you are using Horizon Client for macOS 5.0 or later, this Horizon Collector functionality is included in Horizon Client. No tuning for Network Latency: Low bandwidth / High latency Environments require additional tuning, Please see Tuning Blast Extreme for Wide Area Networks for details. HEVC requires NVIDIA GPUs to be installed in the ESXi hosts to offload encoding. Screen 0/1 @ Resolution: 3840 x 2160. The Horizon Clients can use either IP version 4 or 6. Easily manage VM Profile settings across images. Desktop wallpaper unnecessarily expends both CPU resources to encode and network bandwidth to transfer.

For details about editing View Connection Server settings and security server settings, see the VMware Horizon View Administration documentation. Like the codec and transport options, they can be set using Group Policy or using your preferred method of making registry changes. Internal testing resulted In a 12 percent bandwidth savings by doubling the size of both caches to 512 MB. Using articles, videos, and labs, this activity path provides the fastest way to learn Workspace ONE! NVIDIA H.264 with HighColorAccuracy If the file does not exist, it will create it with the blast settings already enabled. HEVC also requires a client device capable of HEVC GPU decoding. This detail can be observed by reviewing the logs. HEVC supports higher-quality imaging with less bandwidth utilization than H.264. This is simply due to the larger number of pixels that must be supported at higher resolutions. setting, which limits only the display traffic without negatively impacting audio, file transfer, or other supporting services. Use of a solid color with no image or pattern is recommended. For more information see Configuring HTML5 Multimedia Redirectionin Configuring Remote Desktop Features in Horizon 7. : NVIDIA GPUs will also offload H.264 and HEVC encoding. For further information about configuring Blast Extreme to use DSCP marking reference, see. High Efficiency Video Coding, or HEVC for short, is also known as H.265 and is the industry successor to H.264. Fortunately, VMware has developed a free tool to optimize Windows desktops and servers. Get all the Tech Zone demos in one place. VNCEncodeRegionNvEncGetHandle: region encoder NVIDIA NvEnc H264 using YUV 4:4:4 color space. 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).
