• Omnissa Horizon deployments

  Horizon Client for Windows requires the latest maintenance release of one of the following deployment types:

  • Omnissa Horizon 8 version 2006 or later
  • Omnissa Horizon Cloud Service - next-gen
  • Horizon Cloud in Microsoft Azure

• Omnissa Horizon Connection Server and Horizon Agent

  If client systems connect from outside the corporate firewall, use an Omnissa Unified Access Gateway appliance so that client systems do not require a VPN connection. If your company has an internal wireless network to provide routable access to remote desktops that devices can use, you do not need to set up Unified Access Gateway or a VPN connection.

• Display protocols

  • PCoIP
  • Omnissa Horizon Blast
  • RDP

• Network protocols

  • IPv4
  • IPv6 During a custom Horizon Client installation, you can enable the automatic selection of the Internet protocol. For more information, see Enabling Automatic Internet Protocol Selection on Horizon Windows Client. For information about using Horizon in an IPv6 environment, see the Horizon 8 Installation and Upgrade document.

• Hardware requirements for PCoIP and Horizon Blast

  • x86-based processor with SSE2 extensions, with an 800 MHz or faster processor speed.

  • Available RAM above system requirements to support various monitor setups. Use the following formula as a general guide. The unit of measurement is pixels.

    20 MB + (24 * (# monitors) * (monitor width) * (monitor height))
    

    In general, you can use the following calculations.

    1 monitor: 1600 x 1200: 64 MB
    2 monitors: 1600 x 1200: 128 MB
    3 monitors: 1600 x 1200: 256 MB
    

• Hardware requirements for RDP

  • x86-based processor with SSE2 extensions, with an 800 MHz or faster processor speed.
  • 128 MB RAM.

• Software requirements for RDP

  • For Windows 10, use RDP 10.0.
  • The agent installer configures the local firewall rule for inbound RDP connections to match the current RDP port of the host operating system, which is typically 3389. If you change the RDP port number, you must change the associated firewall rules. You can download Remote Desktop Client versions from the Microsoft Download Center.

• Video and graphics requirements

  • Graphics card that supports Direct3D 11 Video.
  • Latest video and graphics card drivers.
