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. It also causes some screen content to letterbox, which may impair user experience. Although this results in a similar reduction in the network bandwidth required, it uses substantially more CPU processing power to encode and decode. Use cases of this caliber nearly always require hardware GPUs to provide the necessary graphics capabilities and acceleration. 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). Note: Dynamic Environment Manager also provides optimization templates for Blast Extreme. Optimized for the mobile cloud, VMware Blast Extreme supports a broad range of client devices, including Windows, Linux, Mac, Android, iOS, Chrome, and web (HTML Access) clients.

Some of the codecs and codec options can be enabled using the Horizon Client, as shown in the following screenshot. 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. 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. The port used by the Blast Secure Gateway on the Unified Access Gateway can be customized (for example, it can use TCP 443). Our Communities feature the top Digital Workspace Experts across the world and 3rd-party content. Blast Extreme is a next-generation display protocol, developed by VMware. Continuing the theme of useful registry key settings you can bake into your image or manually configure for some quick testing, below is a list of corresponding Blast Extreme registry settings to the Horizon 7. Increasing this setting helps improve display quality at the expense of higher bandwidth utilization. Although this strategy makes for reliable delivery, the process adds overhead. This is typically achieved using a Differentiated Services Code Point (DSCP) marking of AF41. 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. 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 lowest currently supported setting). Each setting is a string value (REG_SZ). Encoder Switch: This Continued Visit these other VMware sites for additional resources and content. Horizon Client, on the client device, authenticates and requests a desktop or application. Is there a GPO or something?

For further information about configuring Blast Extreme to use DSCP marking reference, see. MaxBandwidthKbps The maximum bandwidth used by all services (display, keyboard and mouse, audio, file transfer, clipboard, and so on), in kilobits per second. 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. NVIDIA Encoded H.264 These settings are used to configure the address at which clients can reach the specific server when tunneling is in use. EncoderMaxFPS The maximum frames per second that Blast Extreme will display. 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. Figure 3: Group Policy Settings for Blast Extreme. setting, which limits only the display traffic without negatively impacting audio, file transfer, or other supporting services. While typically supporting just a single user, most households do not yet have LAN-speed Internet connections (gigabit Ethernet). It is important to recognize, however, that no display protocol can provide a perfect LAN experience over typical WANs. A TCP WebSocket connection is made from the client to the Blast Secure Gateway on port 8443, and then from the Blast Secure Gateway to the virtual desktop or RDSH server on port 22443. 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. Problem is with second file, which is growing sometimes up to 15GB, then new files are created. EncoderH264Enabled Enables or turns off support for H.264.

Although RAM is rarely the bottleneck, monitor RAM to ensure it is not being over utilized by applications. 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. The following registry settings have been determined through extensive testing to provide the biggest impact on system resources and user experience. Most settings make the option available to be used (set to 1) or not (set to 0). The Connection Server returns the connection information for the virtual desktop or RDSH server to the client. Depending on application workload, 4K displays can use up to six times the resources as 1080P. However, some use cases and situations require additional tuning, especially for wide area networks (WANs). 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. I ended up writing a logon script to solve the problem until VMware fixes it. Note that HDR is an optional capability of HEVC (High Efficiency Video Coding, H.265) and requires an NVIDIA hardware GPU. Log File Locations for Client and Agent Components Blast Extreme supports two transport protocols to carry the display traffic between clients and the Horizon infrastructure: TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).
