To deploy VMware Tunnel with Unified Access Gateway, ensure that your system meets the following requirements:

Hypervisor Requirements

Unified Access Gateway that deploys the VMware Tunnel requires a hypervisor to deploy the virtual appliance. You must have a dedicated admin account with full privileges to deploy the OVF.

Supported Hypervisors
  • VMware vSphere web client
    Note: You must use specific versions of VMware products with specific versions of Unified Access Gateway. The Unified Access Gateway appliance must be deployed on a version of VMware vSphere that is the same as the version supported for the VMware products and versions respectively.
  • Microsoft Hyper-V on Windows Server 2012 R2 or Windows Server 2016

Software Requirements

Ensure that you have the most recent version of Unified Access Gateway. VMware Tunnel supports backwards compatibility between Unified Access Gateway and the Workspace ONE UEM console. The backward compatibility allows you to upgrade your VMware Tunnel server shortly after upgrading your Workspace ONE UEM console. To ensure parity between Workspace ONE UEM console and VMware Tunnel, consider planning an early upgrade.

Hardware Requirements

The OVF package for Unified Access Gateway automatically selects the virtual machine configuration that VMware Tunnel requires. Although you can change these settings, do not change the CPU, memory, or disk space to smaller values than the default OVF settings.

To change the default settings, power off the VM in vCenter. Right-click the VM and select Edit Settings.

The default configuration uses 4 GB of RAM and 2 CPUs. You must change the default configuration to meet your hardware requirements. To handle all the device loads and maintenance requirements, consider running a minimum of two VMware Tunnel servers.

Table 1. Hardware Requirements
Number of Devices Up to 40000 40000-80000 80000-120000 120000-160000
Number of Servers 2 3 4 5
CPU Cores 4 CPU Cores* 4 CPU Cores each 4 CPU Cores each 4 CPU Cores each
RAM (GB) 8 8 8 8
Hard Disk Space (GB)

10 GB for distro (Linux only)

400 MB for installer

~10 GB for log file space**

*It is possible to deploy only a single VMware Tunnel appliance as part of a smaller deployment. However, consider deploying at least two load-balanced servers with four CPU Cores each regardless of the number of devices for uptime and performance purposes.

**10 GB for a typical deployment. Scale the log file size based on your log use and requirements for storing the logs.
