Load Balancing for VMware Horizon (2146312) | VMware KB Troubleshooting Display Issues with the Horizon Blast Protocol (90139) Horizon Client (4.7): Forcing settings by GPO - VMware 3 enabled server to client only. In testing, TCP has been shown to handle high latency better than UDP. 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). This connection is from the client to UDP port 8443 on the Unified Access Gateway. Horizon Client version 5.2 only also requires a special configuration file on the client (see the note following this table). This means the client resorts to CPU decoding, which can result in degraded performance on weak client hardware, particularly when using high-resolution monitors. Deploying Hardware-Accelerated Graphics with VMware Horizon Updated product documentation links to use Horizon 8 documentation. If UDP is enabled on the client, the Unified Access Gateway, and the agent (default), the client attempts to make a UDP connection to the agent via the Unified Access Gateway. HEVC with High Dynamic Range (HDR) Encoding. In testing this has been shown to decrease the amount of network bandwidth used by Blast Extreme. Therefore, it is imperative to start by verifying that all components are sized properly and have sufficient resources and available capacity. Although this results in a similar reduction in the network bandwidth required, it uses substantially more CPU processing power to encode and decode. Figure 4: External Connection from Client to Agent Through the Unified Access Gateway.

If desired, the traffic between the Unified Access Gateway and Horizon Agent can be configured to use a separate port (TCP 9427). See our favorite tools, scripts, and flings from various sites. 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. 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. Diagrams show which ports are used at which locations, and the numbered lists that follow the diagrams show what is happening at each connection. The latest innovation for Blast Extreme is the Blast Codec. Added information about the Blast Codec, which was introduced in the Horizon 7.10 release, and new information about the encoder switch. Tunneling traffic through the Connection Server allows for ports to be open between the Connection Server and the client, and between the Connection Server and the agent, but not between the client and the agent. 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. While most of our environment is running PCoIP, we have also tested with BLAST. Note: Requires Horizon Agent 7.10 and VMware Horizon Client 5.2 or later. Windows display scale to vmware display scaling Learn how to architect the right security solutions for your business needs. Troubleshooting Intermittent Blast Connection Issues in - VMware SwitchEnc: 1 Screen 2 switching to adaptive encoder. This is due to the much higher graphical quality this hardware-enabled configuration provides. The Horizon Performance Tracker does not currently display the codec currently being used per screen by the encoder switch. In testing, viewing a YouTube video in a standard window instead of full-screen reduced bandwidth utilization by 53 percent. This gateway then directs the traffic to the correct port and location on the Connection Server and agent. Explore the latest VMware tools designed to get your end-user computing environment running smoothly and efficiently. Blast Extreme uses the latest security algorithms, including SHA-256. compression format. Increase the frame rate. Using VMware's Horizon Performance Tracker For Rudimentary Blast This can help determine the best architecture, understand the traffic flow, and network ports, and help in troubleshooting. Note: At this point, the VMware Blast service on the agent side (Horizon Agent on the virtual desktop or RDSH server) proxies the incoming connection. (maximum display bandwidth) to either the circuit speed or the maximum desired bandwidth utilization per user.The former option allows Blast to burst and use more bandwidth when necessary, while the latter attempts to more strictly control it. Access technical, third-party tips, tricks, and how-tos. If UDP is enabled on the agent (default), the Blast Proxy process (in Horizon Agent) attempts to make a UDP WebSocket connection to the client on port 22443. The VMware Workspace ONE and Horizon Reference Architecture guide provides guidance for architecting Workspace ONE and Horizon deployments. 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. A monitor at 4K resolution requires up to six times the bandwidth for the same application workload as 1080p. Limiting the resolution of employees monitors also greatly reduces Internet circuit bandwidth utilization. However, if the network also supports interactive video, Blast Extreme is often marked one-level lower with a DSCP marking of AF31. Note: for all settings in the following table, if the key is set to 1 support is enabled; if it is set to 0 support is turned off. 1 In VMware Horizon, when using PCoIP Secure Gateway on the Connection Server or Security Server. But it can also be used to support graphically intensive applications by leveraging the desktops physical GPU. Horizon 7.10: Enabling dynamic codec switching MaxBandwidthKbpsPerMegaPixelSlope The maximum bandwidth used to transfer screen contents per megapixel remoted, in kilobits per second. Another important aspect to consider is the size of the monitor (or monitors) to be used, and their screen resolutions. 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. These pages help you understand the breadth of our most popular products. 2 enable file upload only By default, they are expected to be installed on dedicated, physical hardware, and not separated from their intended users by networks and display protocols. We have many more paths than are shown here. 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. VNCSERVER-WIN32: ***Setting topology completed by Nvidia Display***. Horizon with Blast 3D and Blast Performance - VMware Use our product forums to engage with the community. The log files are located in: :\ProgramData\VMware\VMware Blast\. : Because port sharing incurs some performance overhead on Unified Access Gateway, port sharing is not the preferred configuration. Deploy virtual desktops and RDSH servers on fast virtual disks (all-flash or flash-optimized). VMware Blast Extreme Other codec options can only be enabled by administrators and also require a corresponding Horizon Client setting. If the file does not exist, it will create it with the blast settings already enabled. VMware Blast Extreme GPO Registry Keys - FROGGYJ In addition to leveraging all of the optimizations described in the preceding section for still images, 3D design, and font quality, try the following suggestions: VMware Horizon and Blast Extreme support not just virtual desktops, but physical ones too.
