Initial Setup

The Aruba Clarity Engine provides proactive analysis of end user quality of experience by monitoring critical network services. This document describes how to install the Clarity Engine.

System Requirements

Listed below are the minimum hypervisor host system requirements for the Clarity Engine to run as a guest virtual machine (VM) and the resources required for the VM to be functional:

l Quad-core Core i5 1.9 GHz processors with hyper threading enabled

l 8 GB RAM

l Minimum 2 physical network interface cards (NICs) on the ESXi host

Deploying the OVA template on the VM requires:

l 4 vCPU

l 4 GB RAM

l 128 GB Disk

TheClarity Engine OVA template cannot be installed on the samevirtual machine instance as AirWave. The Clarity Engine needs its own virtual machine instance.

The following illustration shows the topology of the Clarity Engine in your network.
