Adjustable Encoder Image Cache Size and Decoder Image Cache Size settings. After you apply the policy, the system stores the settings in the registry key HKLM\Software\Policies\VMware, Inc.\VMware Blast\config. For details about port requirements for connectivity between the various components and servers in a Horizon deployment, see Network Ports in VMware Horizon. (Requires NVIDIA GPU). Utilize this tool to get you part of the way there. This step-by-step setup of VSs leverages the Kemp application template for Horizon 7 and Horizon 8. Blast Extreme is a next-generation display protocol, developed by VMware. 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. I'm sure this feature looked awesome on paper. Use NVIDIA GPUs. H264maxQP The lowest quality that H.264 will start with before building the screen to higher quality. There is something for every experience level. Broad client support, including Windows, Linux, Mac, Android, iOS, Chrome, and web (HTML Access) clients. A certificate thumbprint is a cryptographic hash of a certificate. A monitor at 4K resolution requires up to six times the bandwidth for the same application workload as 1080p. Blast Extreme now supports four codecs: JPG/PNG, H.264, High Efficiency Video Coding (HEVC), and the new Blast Codec. These pages help you understand the breadth of our most popular products. Most settings make the option available to be used (set to 1) or not (set to 0). Use our product forums to engage with the community. 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. Follow these guidelines: Note that while the optimizations in this section are typically used with WANs, they can also be used on the LAN if Blast Extremes default settings use more bandwidth or other resources than desired. Join the community by engaging in forums, events, and our premier community programs. Fortunately, this processing can be offloaded from the CPU to graphics cards (GPU) in the device. Be certain to test key applications and multimedia content before widespread deployment. Access technical, third-party tips, tricks, and how-tos. Feature parity with the VMware PCoIP display protocol. On the Security Server, run the downloaded VMware-Horizon-Connection-Server-x86_64-7.13.2.exe. Desktop wallpaper unnecessarily expends both CPU resources to encode and network bandwidth to transfer. Learn how to architect the right security solutions for your business needs. VMware has built a set of tools and resources to support you and your team as you build out an adoption strategy. 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. Testing has shown this reduces the bandwidth required to support such content by up to 80 percent. Turn on the sound card: Fusion 7.x and above: Ensure Connect Sound card option is checked. See. The encoder switch dynamically switches between either the JPG/PNG codec or the Blast Codec, and H.264, depending on the screen content type. Some even suffer from packet loss, where packets never arrive at the destination at all! The encoder switch also supports High Color Accuracy (HCA) for H.264, enabling it to be used for multimedia content that exhibits color problems or lack of clarity with H.264 alone. It also causes some screen content to letterbox, which may impair user experience. MaxBandwidthKbpsPerMegaPixelSlope The maximum bandwidth used to transfer screen contents per megapixel remoted, in kilobits per second. Highlight the Security Server, then click the menu named More Commands and click Prepare for Upgrade or Reinstallation. Computer Configuration -> Policies -> Administrative Templates -> VMware Blast -> Max Frame Rate. The Blast Extreme template is named: vdm_blast.admx and can be found in the VMware-Horizon-Extras-Bundle-xxx.zip file, with xxx indicating the corresponding version of Horizon. Added guidance on the benefits of HTML5 multimedia redirection. For external connections: Unified Access Gateway 2.9 or later. But when rapidly changing screen content such as streaming video is detected, Blast Extreme automatically switches to multimedia optimized H.264. In this mode, the codec is able to support applications that require the display protocol to be lossless, ensuring nothing is lost in transmission. The encoder switch ensures that the most efficient codec is dynamically used based on screen content. Applications and use-cases that require higher quality typically have demanding graphical requirements that can only be supported by hardware GPUs. 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. More information about the admin settings is provided in the next section of this chapter. Workspace ONE Access, formerly known as Identity Manager, is a powerful tool. 2 When RDP protocol is tunneled through the Connection Server or Security Server. Screen 0/1 @ Resolution: 3840 x 2160. 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. One of the goals for Blast Extreme 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. HEVC will not work with ESXi CPU encoding alone. Welcome to VMware Digital Workspace Tech Zone, your fastest path to understanding, evaluating, and deploying VMware End User Computing products. These encryption mechanisms apply to the H.264, H.265, and JPG/PNG codecs. Learn how to architect the right security solutions for your business needs. 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. NVIDIA H.264 with HighColorAccuracy Essa conexo fornece o nvel necessrio de segurana e conectividade ao . 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. (maximum display bandwidth) to the maximum desired bandwidth utilization per user. Problem is with second file, which is growing sometimes up to 15GB, then new files are created. Blast Extreme supports four codecs: JPG/PNG, H.264, HEVC (H.265), and the new Blast Codec. Instructions for configuring all of the Blast Extreme codec options are provided in the next chapter, How to Configure Blast Extreme. 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. 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 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. Testing has shown this enables smooth 4K video playback without need for hardware GPUs. 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). 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. 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. Note that this increases bandwidth and virtual desktop CPU utilization. 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. Screen 0/1 @ Resolution: 3840 x 2160. In a typical environment, the admx policy files go into \\<domain name>\SYSVOL\<domain name>\Policies\PolicyDefinitions. Caroline Arakelian is a Senior Technical Marketing Manager, End-User-Computing Technical Marketing, VMware. Use of a solid color with no image or pattern is recommended. Like high latency, tuning for packet loss starts with reducing bandwidth. It is extremely important to recognize that optimizing for higher quality nearly always results in more system resources being used, not less. Developed for a variety of workloads, Blast is optimized for an ideal user experience and resource consumption. NVIDIA Encoded H.264(H.264 Offloaded to GPU). Encoder Switch: JPG/PNG and H.264 with HCA. Most Macs, laptops, and Windows PCs manufactured in 2013 or later. Using articles, videos, and labs, this activity path provides the fastest way to learn Workspace ONE! Explore how VMware can help solve an IT team's most pressing digital workspace challenges. 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. The evaluation process has been initiated. The author wishes to thank the following people for their contributions to this paper and the growing knowledge of how to optimize VMware Blast Extreme: To comment on this paper, contact VMware End-User-Computing Technical Marketing at euc_tech_content_feedback@vmware.com. However, it is a new and rapidly evolving codec. Do not starve the virtual desktops and RDSH servers of resources. Use TCP if latency is greater than 250 milliseconds. Incorporated various recent suggestions from reviewers. VMware Blast: H. 264 Quality. This detail can be observed by reviewing the logs. NVIDIA Ampere A10 and A40 GPUs. EncoderAdaptiveEnabled Enables or turns off support for the VMware JPG/PNG codec. Yes: Select Allow High Efficiency Video Coding and Allow High Dynamic Range Decoding (HDR). Increase the frame rate. FIPS-ready libraries are available for Unified Access Gateway 2.9 or later appliances. 1 enabled in both directions If the testing in your environment is not successful, use JPG/PNG. HEVC can also support higher quality at similar compression ratios as H.264, but again at the cost of more processing power with no bandwidth savings. If full-motion graphics must be supported, such as streaming video, use the encoder switch to dynamically switch between the Blast Codec or JPG/PNG and the H.264 codec. Yes: Select Allow High Efficiency Video Coding. The VMware Blast service ( VMBlastS.exe) manages user sessions, proxies incoming TCP connections, and prepares the Blast Worker process. VMware Blast Extreme Group Policy Settings The policy files required are vdm_blast.admx and vdm_blast.adml. There is something for every experience level. Increasing this setting helps improve display quality at the expense of higher bandwidth utilization. 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. 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. For other browsers, the JPG/PNG codec is used. ) JpegQualityLow The lowest quality JPG/PNG will start with before building the screen to higher quality. Some of the codecs and codec options can be enabled using the Horizon Client, as shown in the following screenshot. HEVC supports higher-quality imaging with less bandwidth utilization than H.264. MinBandwidthKbp and MaxBandwidthKbps also impact all services, including audio and file transfer, while MaxBandwidthKbpsPerMegaPixelSlope only limits the bandwidth used to transfer the screen contents. The Blast Codec should be evaluated for use whenever network bandwidth or display protocol CPU utilization is a primary concern. Begin your journey leveraging cloud-based services for desktop environments. The Connection Server returns the connection information for the virtual desktop or RDSH server that provides remote applications (on TCP port 443). Visit these other VMware sites for additional resources and content. The Blast Worker process ( VMBlastW.exe) captures the screen and handles everything within the session. manages user sessions, proxies incoming TCP connections, and prepares the Blast Worker process. ) It is better to leverage HTML5 multimedia redirection to optimize such use cases.
