Blast can deliver a decent experience with default settings, however, some networks and scenarios need additional tuning. 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. 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. Solved: clipboard redirection - VMware Technology Network VMTN Like HEVC, the encoding for H.264 and H.264 with HCA can be offloaded to NVIDIA GPUs installed in the ESXi hosts. If users experience any of these issues, HCA can be enabled to improve quality while preserving H.264s multimedia efficiency. On the right, switch to the tab named Security Servers. The Blast Codec should be evaluated for use whenever network bandwidth or display protocol CPU utilization is a primary concern. Reducing network bandwidth is key to enabling support for all adverse network conditions. The Horizon Client authenticates to a Connection Server through the Unified Access Gateway. Mark Ewert is a Senior Product Line Manager, EUC Desktop Products, VMware. Broad client support, including Windows, Linux, Mac, Android, iOS, Chrome, and web (HTML Access) clients. EncoderH264YUV444 Enables or turns off support for High Color Accuracy for H.264. The VMware Workspace ONE and Horizon Reference Architecture guide provides guidance for architecting Workspace ONE and Horizon deployments. 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 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. Depending on application workload, 4K displays can use up to six times the resources as 1080P. Therefore, images compressed using JPG cannot be decoded and restored to the same quality they had before compression. (Requires NVIDIA GPU), VNCRegionEncoder_Create: region encoder NVIDIA NvEnc HEVC. VNCRegionEncoder_Create: region encoder BlastCodec. Install VMware Horizon Client on end users' machines and have end users access their remote desktops and applications. Blast Extreme can also use the certificate thumbprint of the Blast Secure Gateway or virtual desktop. Windows display scale to vmware display scaling also impact all services, including audio and file transfer, while. Deselect all other codecs and codec options. Display resource-intensive multimedia content in a window instead of full screen. Question: 1. Click the View All button for the full list. Testing has shown this reduces the bandwidth required to support such content by up to 80 percent. Let us help you learn how to use it. The Connection Server returns connection information for the virtual desktop or RDSH server that provides remote applications (on TCP port 443). 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. This provides increased scalability and better performance, especially in CPU-constrained ESXi environments without NVIDIA GPUs. Monitor for high CPU Ready times (which are evidence of processor contention). Added new observations on the impact of increasing screen resolution on key system resources. Then check with the "VMware Horizon Performance Tracker . Understand the basics of VMware Blast Extreme vs. PCoIP Test the new Blast Codec unless this use-case is primarily in support of full motion video or high-speed motion graphics such as gaming. Go to https://my.vmware.com/web/vmware/downloads. This detail can be observed by reviewing the logs. Even when there might be sufficient bandwidth, such as for a home-based user with a high-speed cable network connection, be certain to validate end-to-end bandwidth, latency, and packet loss before deciding if the use case can be supported. These formats employ compression to reduce the size of the content before it is transferred across the network. Our Communities feature the top Digital Workspace Experts across the world and 3rd-party content. Access technical, third-party tips, tricks, and how-tos. 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. VMware Horizon Blank Screen - The Tech Journal Display communication protocols provide end users with a graphical interface to a remote desktop or published application. Use HTML5 multimedia redirection if resource-intensive web-browser-based content such as YouTube or eLearning streaming video must be supported. 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. Learn how to architect the right security solutions for your business needs. General Settings - VMware Although Blast Extreme has been able to provide a functional desktop and application experience when packet loss is in excess of 20 percent, it is with noticeable degradation to user experience. 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). (which like all VMware flings, is not officially supported). Before tuning Blast Extreme, it is critical to properly size and optimize the virtual desktops, physical desktops, Microsoft RDSH servers, and supporting infrastructure. 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. 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. 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. This directory contains logs for the three Blast Extreme components: For more information about the entries in these log files, see How to Verify Configuration in the VMware Blast Extreme Optimization Guide. NVIDIA H.264 with HighColorAccuracy Horizon with Blast 3D and Blast Performance - VMware Keep in mind that this may complicate WAN use cases. 1 enabled in both directions 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 become the hero of your department. It turns off or tunes the elements that unnecessarily waste system resources when used in shared, virtual environments. If desired, the traffic between the Unified Access Gateway and Horizon Agent can be configured to use a separate port (TCP 9427). Yes: Select Allow H.264 Decoding. With an internal connection, the client, the server, and the virtual desktop or RDSH server are all inside the corporate network. Blast Extreme will always resort to using more bandwidth, if necessary, to prevent the session from crashing. This is great for users that use their own devices with all kinds of displays and DPI settings and such. Keep in mind, however, that Blast Extreme will always resort to using more bandwidth, if necessary, to prevent the session from crashing. Same applications that are ideal for H.264 while offloading the encoding from the ESXi host CPUs to an NVIDIA GPU. Figure 3: Tunneled Connection from Client to Agent Through the Connection Server. Actual results will depend on the application workloads and usage patterns. Log File Locations for Client and Agent Components 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 recommends use of Network QoS to prioritize display protocol network traffic, not just on constrained WAN circuits, but even on the LAN as well. Yes: Select Allow H.264 Decoding, and select Allow High Color Accuracy. The Blast Worker process determines whether UDP is enabled on the agent and allowed on the client. EncoderImageCacheSizeKB Introduced in Horizon 8 (2111). The table in each section outlines the settings configured by the application template. Horizon Client version 5.2 only also requires a special configuration file on the client (see the note following this table). Contains entries that tell you whether JPG/PNG or the H.264 coded is being used. Navigate to Virtual Machine > Settings (Fusion) or VM > Settings (Workstation). SwitchEnc: 1 Screen 4 switching to BlastCodec encoder. Screen 0/1 @ Resolution: 3840 x 2160. However, it is important to note that building-to-lossless increases session bandwidth utilization because more display information is sent across the network. These pages help you understand the breadth of our most popular products. The actual size of the cache will be the lesser of this value, and the value of DecoderImageCacheSizeKB set on the client but cannot exceed half of the available RAM. Horizon Agent 7.5 or later is required; Horizon Agent 7.10 or later is recommended. : NVIDIA GPUs will also offload H.264 and HEVC encoding. Optimize the desktops and RDSH servers using the VMware Operating System Optimization Tool. Be certain to test key applications and multimedia content before widespread deployment.

SwitchEnc: 1 Screen 0 switching to h264 4:4:4 encoder. 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. Start with these recommendations before moving on to more specialized settings. 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. Using Horizon to Access Physical Windows Machines | VMware 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. Another important aspect to consider is the size of the monitor (or monitors) to be used, and their screen resolutions. However, some use cases and situations require additional tuning, especially for wide area networks (WANs). The traffic uses the native port for each of the remote experience features between the Connection Server and the agent: With an external connection, the client is connecting from outside the corporate network to the Unified Access Gateway. Begin your journey leveraging cloud-based services for desktop environments. Information on how to enable build-to-lossless mode is covered in the next chapter, How to Configure Blast Extreme. In testing, TCP has been shown to handle high latency better than UDP. 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. Graeme Gordon is a Senior Staff End-User-Computing Architect, EUC Technical Marketing, VMware. Typical Microsoft Office use, for example, results in a very low display protocol frame rate. Special note about NVIDIA GPU supported use cases: Using NVIDIA GPUs to support H.264 and High Efficiency Video Coding (HEVC) substantially increases session bandwidth. HEVC also requires clients to have graphics cards with H.265 decode support, but fortunately, as with H.264, most client devices manufactured since 2015 have them.
