The VMware Operating System Optimization Tool can be downloaded from, https://flings.vmware.com/vmware-os-optimization-tool. WANs typically have just a fraction of the bandwidth that is available on local area networks (LANs). Type: REG_SZ. Before tuning Blast Extreme, it is critical to properly size and optimize the virtual desktops, physical desktops, Microsoft RDSH servers, and supporting infrastructure. By default, the traffic is then side-channeled on the Blast Extreme channel to the agent. Start with these recommendations before moving on to more specialized settings. Introduced in Horizon 8 (2106) is support for High Dynamic Range (HDR) encoding to provide higher graphical quality with vastly improved color range and contrast. (Requires NVIDIA GPU), VNCRegionEncoder_Create: region encoder NVIDIA NvEnc HEVC. Become a desktop virtualization hero with our curated activity path. 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 possible, prevent or encourage only limited use of bandwidth-intensive services such as file transfer. Horizon is a complete solution that delivers, manages, and protects virtual desktops, RDSH-published desktops, and applications across devices and locations. Note: Setting this option to 100 will not provide a lossless image. It is important to recognize, however, that no display protocol can provide a perfect LAN experience over typical WANs. Computer Configuration -> Policies -> Administrative Templates -> VMware Blast -> Max Frame Rate. Client-drive redirection traffic uses TCP 9427. or you can specify that users can choose the protocol. The former option allows Blast Extreme to burst and use more bandwidth when necessary, while the latter attempts to more strictly control it. The following diagram shows the ports used for an internal tunneled connection, and the list that follows describes the order in which the connections are made. The following registry settings have been determined through extensive testing to provide the biggest impact on system resources and user experience. Critical Horizon features and components, such as the Blast Extreme display protocol, instant-clone provisioning, VMware App Volumes application delivery, and VMware Dynamic Environment Manager , are integrated with published applications and desktops to provide a seamless user experience and an easy-to-manage, scalable solution. 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. Get to know and understand the Anywhere Workspace solution. With non-multimedia workloads, the Blast Codec uses the least bandwidth compared to all other codec options. Because H.264 also provides good support for most Windows, Linux, and macOS applications, it is also the default Blast Extreme codec option. 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 Blast Extreme uses the H.264 video encoding standard which any modern mobile device can handle in its GPU, rather than CPU. If the testing in your environment is not successful, use JPG/PNG. For more information see Configuring HTML5 Multimedia Redirectionin Configuring Remote Desktop Features in Horizon 7. 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. Like the codec and transport options, they can be set using Group Policy or using your preferred method of making registry changes. We have many more paths than are shown here. For a detailed list of Blast Extreme features, see the VMware Blast Extreme topic in the VMware Horizon Architecture Planning guide. This means that display content encoded and compressed using PNG alone can be restored to match the quality of the original content. Monitor for high CPU Ready times (which are evidence of processor contention). In other words, the settings do not directly enable the feature, such as forcing all connections to use H.264. 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. 1 enabled in both directions Another key Blast Extreme innovation is the encoder switch. Using articles, videos and labs, this activity path provides the fastest way to learn Workspace ONE! When multimedia redirection (MMR), client-drive redirection (CDR), USB redirection, or some combination of these are enabled by the administrator, this traffic goes through the HTTPS Secure Tunnel on the Connection Server. Let's set this to "Enabled" and set it to 60. Same applications as for the Blast Codec and the H.264 with HCA codec. Deploy virtual desktops and RDSH servers on fast virtual disks (all-flash or flash-optimized). Blast Extreme will always resort to using more bandwidth, if necessary, to prevent the session from crashing. Many of the codec options and Blast Extreme settings can be controlled by administrators. They are downloaded as part of the VMware-Horizon-Extras-Bundle. HEVC provides up to 50 percent better compression with the same quality as H.264. 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. 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. 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. NVIDIA Encoded H.264(H.264 Offloaded to GPU). 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.

You can combine GPU with PCoIP and blast settings to adjust video performance, frame rate (frames per second), i mage quality level, based on your available . However, this example can be achieved by disabling support for the H.264 codecs competing options: JPG/PNG and HEVC. 2 enable file upload only VNCSERVER-WIN32: ***Setting topology completed by Nvidia Display***. hosts to support other tasks, which ultimately increases scalability. This gateway then directs the traffic to the correct port and location on the Connection Server and agent. These settings are used to configure the address at which clients can reach the specific server when tunneling is in use. The following table documents the key codec and transport settings. Problem is with second file, which is growing sometimes up to 15GB, then new files are created. Yes: Select Allow H.264 Decoding, and select Allow High Color Accuracy. Applications that require higher graphical quality with improved color range and contrast, such as digital photography. What about frame rate? If the UDP connection is successful, Blast assesses the networks condition to decide whether to use TCP or UDP for session traffic. Get to know EUC vExperts from around the world. 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). This KB outlines the top trending cause associated with an intermittent external screen redirection issue with the Blast Protocol over Unified Access Gateway (UAG) If bandwidth needs to be limited, start with the. HEVC with High Dynamic Range (HDR) Encoding. 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. However, it is important to note that building-to-lossless increases session bandwidth utilization because more display information is sent across the network. Adust the Blast Encoder Image Cache Size and the Decoder Image Cache Size. If you are using Horizon Client for macOS 5.0 or later, this Horizon Collector functionality is included in Horizon Client.
