Virtual Appliance Pre-Requisites

Deploy UNUM as a VM (Virtual Machine) on a VMware ESXi Hypervisor.

Currently, UNUM 6.3.x requires either ESXi, VMware vSphere Enterprise, VMware vSphere Standard, and vCenter 6.7 versions.

For High Availability (HA), UNUM supports both VMware vSphere Enterprise and VMware vSphere Standard with applicable licensing.

We do not support other VMware versions for UNUM 6.3.x

Please consult the specific UNUM Release Note for the UNUM version you are using for more information regarding supported VMware versions.

The instructions in this document assume the administrator has access to a VMware vCenter console with privileges adequate to create a Virtual Machine and has the necessary Linux system administration skills.

VM comes in an OVA format.

The UNUM VM requires the following: 

UNUM virtual machine (software) and server hardware requirements can vary based on the UNUM options chosen (BASE, Medium Capacity, or High Capacity). Please refer to the UNUM datasheet tables for the most up-to-date requirements.

Network: three Ethernet interfaces configured as:

Note: Please carefully review the following usage information regarding the Ethernet adapters used by UNUM.


used for management, GUI (user interaction) and data collection via Netvisor REST. This interface uses DHCP by default.


Eth1: is used for internal system communication. A standalone UNUM VM instance REQUIRES the use of an IP address for eth1 before normal operations begin. Pluribus Networks recommends adding the Eth1 IP address to a dummy vSwitch and a separate dummy subnet on the ESXi host.

WARNING! If you change the IP address of Eth1 in a cluster configuration, you disrupt normal operations. Please contact Pluribus Networks Technical Support if you need or want to change the Eth1 address in a cluster configuration.


<Optional> used to connect a Seed Switch or Fabric via an inband connection.

Note: To connect more than one Fabric via inband and external switch is required.
