Preparing virtual NAM Probe machine

This procedure describes how to install the NAM Probe software on a VMware virtual machine. If you are installing the NAM Probe on a physical machine, go to Preparing NAM Probe hardware.

To create a complete NAM Probe installation, you need to:

  1. Set up a suitable server (physical or virtual).
    You Are Here
  2. Install a supported version of Linux
  3. Configure the NAM Probe communication interface
  4. Install the NAM Probe software

Creating a VMware virtual machine

In the vSphere Client, create a virtual machine to host the NAM Probe software.

Select File  ► New  ► Virtual Machine to open the Create New Virtual Machine wizard.

On the Configuration screen, set Configuration to Custom .

On the Name and Location screen, set Name and Inventory Location to the name and data center of your choice.

On the Resource Pool screen, choose the resource pool or ESX host where this virtual machine will be placed.

On the Storage screen, choose a datastore for the virtual machine.

On the Virtual Machine Version screen, set Virtual Machine Version to the latest version to get the latest features and best performance.

On the Guest Operating System screen, set Guest Operating System to Linux and set Version to Red Hat Enterprise Linux (64-bit) .

On the CPUs screen, set Number of virtual sockets to 2 and set Number of cores per virtual socket to 1 .

This configuration can be increased later as needed, but internal testing has shown this configuration to be an adequate starting point.

On the Memory screen, set Memory Size to 8 GB .

This configuration can be increased later as needed, but internal testing has shown this configuration to be an adequate starting point.

On the Network screen, add the appropriate number of virtual NICs.

Add at least one NIC for communications between the NAM Probe and other NAM components plus one NIC for each port group that you intend to monitor.

Assign each NIC to the appropriate Network and set Adapter to VMXNET3 .

On the SCSI Controller screen, set SCSI controller to the type that best suits your vSphere infrastructure.

We recommend LSI Logic Parallel .

On the Create a Disk screen, create a virtual disk and specify a capacity.

Click Finish.

What to do next

The NAM Probe platform must be running a supported version of Linux.

  • To create a fresh Linux installation using the kickstart option, see Installing Linux with kickstart.
    This is the most automated (easiest) and most reliable (less room for setup error) option, but you cannot choose this option if your environment requires you to use an existing Linux installation or to configure a new Linux installation manually.

  • To install the NAM Probe on an existing Linux installation, or to install Linux using default options and then resolve any software dependencies and conflicts manually, see Installing Linux without kickstart.
    This is not the easiest option, but it may be necessary to meet the requirements of your working environment.
