Installing NFO Virtual Appliance

To deploy the NFO virtual appliance, follow the standard OVF deployment procedure.

Download the NFO virtual appliance. VMware distributes the NFO virtual appliance as an .ova file. Deploy the NFO virtual appliance by using the vSphere Client.

Prerequisites

  • Verify that you have a copy of the NFO virtual appliance .ova file.

  • Verify that you have permissions to deploy OVF templates to the inventory.

  • Verify that your environment has enough resources to accommodate the minimum requirements of the NFO virtual appliance. See Minimum Requirements.

  • Verify that you read and understand the virtual appliance sizing recommendations. See Sizing the NFO Virtual Appliance.

Procedure

Please use Edit Settings functionality in vSphere Client to make changes to Networking Properties and Other Properties. If you make any changes of these properties directly in OS, they will be overwritten on reboot of VM. CAUTION Do not specify more than two domain name servers. If you specify more than two domain name servers, all configured domain name servers are ignored in the NFO virtual appliance.

  1. In the vSphere Client, select File > Deploy OVF Template.

  2. Follow the prompts in the Deploy OVF Template wizard.

  3. On the Deployment Configuration page, select the size of the NFO virtual appliance based on the size of the environment for which you intend to collect NetFlow.

  4. On the Disk Format page, select a disk format.

  • Thick Provision Lazy Zeroed creates a virtual disk in a default thick format. Space required for the virtual disk is allocated when the virtual disk is created. The data remaining on the physical device is not erased during creation, but is zeroed out on demand at a later time, on first write from the virtual appliance.

  • Thick Provision Eager Zeroed creates a type of thick virtual disk that supports clustering features such as Fault Tolerance. Space required for the virtual disk is allocated at creation time. In contrast to the flat format, the data remaining on the physical device is zeroed out when the virtual disk is created. It might take much longer to create disks in this format than to create other types of disks.

IMPORTANT: Deploy the NFO virtual appliance with thick provisioned eager zeroed disks whenever possible for better performance and operation of the virtual appliance

  • Thin Provision creates a disk in thin format. The disk grows as the data saved on it grows. If your storage device does not support thick provisioning disks or you want to conserve unused disk space on the NFO virtual appliance, deploy the virtual appliance with thin provisioned disks.

  1. On the Properties page, set the networking parameters for the NFO virtual appliance. If you do not provide network settings, such as IP address, DNS servers, and gateway, NFO utilizes DHCP to set those settings.

CAUTION Do not specify more than two domain name servers. If you specify more than two domain name servers, all configured domain name servers are ignored in the NFO virtual appliance.

Use comma to separate domain name servers.

  1. On the Properties page, set the root password for the NFO virtual appliance.

  2. Follow the prompts to complete the deployment. For information on deploying virtual appliances, see the User's Guide to Deploying vApps and Virtual Appliances.

After you power on the virtual appliance, an initialization process begins. The initialization process takes several minutes to complete. At the end of the process, the virtual appliance restarts.

  1. Navigate to the Console tab and check the IP address of the NFO virtual appliance.

IP Address Prefix

Description

https://

The DHCP configuration on the virtual appliance is correct.

http://

The DHCP configuration on the virtual appliance failed. If it is failed:

  • Power off the NFO virtual appliance.

  • Right-click the virtual appliance and select Edit Settings.

  • Set a static IP address for the virtual appliance.

What to do next

  • To enable SSH connections to the NFO virtual appliance, configure the root password in the virtual appliance console. See Configure the Root SSH Password for the NFO Virtual Appliance.

  • The NFO Web interface is available at https://<nfo-host>:8443 where NFO-host is the IP address or host name of the NFO virtual appliance.

  • Log in to NetFlow Optimizer, apply license, and continue configuration. See Configuring NFO in NetFlow Optimizer Administration Guide for more information.

  • You can change the time synchronization settings in the NFO virtual appliance after deployment. Two methods of the time synchronization are available: either by using an NTP server or by using VMware Tools. By default, the NFO virtual appliance uses VMware Tools for the time synchronization. If you want change it to use an NTP server, disable VMware Tools time synchronization before, see picture below.

Do not applying both methods of the time synchronization simultaneously!
