Unified Access Gateway (UAG) is a secure gateway appliance that provides access to VMware Horizon based resources such as virtual desktops, RDSH-based applications, and physical Windows machines. UAG supports multiple authentication methods and protocols, such as SAML, OAuth, and RADIUS, to provide secure access to end users from any device and location.UAG also provides edge services such as load balancing, high availability, and firewall rules to optimize the performance and availability of Horizon based resources12.Reference:=1: VMware Horizon Architecture Planning:Unified Access Gateway2: VMware Unified Access Gateway Administration Guide:Introduction to Unified Access Gateway

VMware Horizon Agent for Linux is a software component that enables Linux machines to be used as remote desktops or published applications in a Horizon environment.Horizon Agent for Linux supports several features that enhance the user experience and manageability of Linux desktops and applications, such as USB redirection, display protocol PCoIP, multiple-session mode, single sign-on, smart card authentication, and 3D graphics34.However, Horizon Agent for Linux does not support location based printing or session collaboration features that are available for Windows machines5.Also, Horizon Agent for Linux does not require installation registration as it automatically registers with the Connection Server when the viewagent service is started6.Reference:=3: VMware Horizon 8 Documentation:Horizon Agent for Linux4: VMware Horizon 8 Documentation:Features Supported by Horizon Agent for Linux5: VMware Horizon 8 Documentation:Features Not Supported by Horizon Agent for Linux6: VMware Horizon 8 Documentation:Install Horizon Agent on a Linux Machine

The issue described indicates that the Horizon Connection Server is incorrectly handling traffic that should be directed to the Unified Access Gateway (UAG) and then to the VDI desktops. Disabling the Tunnel and Gateways settings on the Horizon Connection Server forces the UAG to handle the Blast traffic directly, ensuring that the connections are made to the VDI desktops' IP addresses, thus resolving the black screen and disconnection issue.

Enabling Quiesce Mode in the Unified Access Gateway (UAG) Admin UI is the recommended approach for minimizing downtime during maintenance or upgrades when the UAG is part of a load-balanced cluster. Quiesce Mode allows the UAG to stop accepting new connections while allowing existing sessions to continue until they naturally end. This ensures minimal disruption to users and allows for a controlled upgrade process.

Configuring BLAST Bandwidth Profiles involves setting quality, maximum session bandwidth, and frame rate controls. This can be effectively managed using Horizon Smart Policies within VMware's Dynamic Environment Manager (DEM), which allows administrators to create contextual policies that dynamically adapt to the end-user's environment. Alternatively, Group Policy Objects (GPOs) can be used to manually set these configurations across the desktop environment, providing a more static approach to enforcing these settings.

To expand a Writable Volume in VMware Horizon, the administrator needs to navigate to the Volumes > Writables section in the Horizon Console, select the specific volume, and choose the option to update or expand the writable volume. The new size specified must be at least 1GB larger than the current size to ensure there is enough space for the expansion process and to accommodate the growth of user data.

RADIUS (Remote Authentication Dial-In User Service) supports two-factor authentication and can be integrated with VMware Horizon to secure administrative access to the Horizon Console. RADIUS servers authenticate users based on a combination of something they know (a password) and something they have (a token or mobile app-generated code), providing an added layer of security for administrative logins.

VMware vSAN is a storage product that allows the pooling of resources to create datastores in a software defined datacenter. VMware vSAN is a hyper-converged infrastructure solution that integrates compute, storage, and networking resources on industry-standard x86 servers. VMware vSAN aggregates local or direct-attached data storage devices to create a single storage pool shared across all hosts in the vSAN cluster. VMware vSAN enables you to provision and manage storage from the VMware vSphere Web Client or the VMware vCenter Server Appliance Shell.VMware vSAN provides several benefits, such as lower total cost of ownership, simplified management, high performance, scalability, and availability12.Reference:=1: VMware Horizon 8 Documentation:VMware vSAN Overview2: VMware Horizon 8 Documentation:Benefits of Using VMware vSAN with Horizon 8
