VMware NSX PowerShell Installation and System Requirements – In this blog post we would look at the minimal system requirements of installing VMware NSX and also look at how you can automate the installation using PowerCLI cmdlets.

If you want to understand what is VMware NSX and how it helps to achieve a 100% virtualized SDDC implementation have a look at one of my previous blog post on VMware NSX : Why we need it in SDDC

So lets look at the initial system requirements of Installing NSX :-

a) You need to be running vSphere 5.5 or later (vSphere 6.0, the latest release at the time of this blog post).

b) You would need to have vCenter 5.5 or later installed on your vmware environment.

c) You need to have an Enterprise Plus license, this license is required as it supports VDS or the    vSphere distributed switch which is one of the core component to enable the usage of NSX

d) Also you need the support of MTU or Jumbo Frames, this is required for NSX.

Next look at how you can install NSX using PowerCLI.

First thing you need is to head over to the VMware Download Portal and Download the OVA file for NSX.

Once you download the NSX OVA file, launch a powershell console and type in the below commands.

Once you import the config in the $ovfconfig variable, update the properties for each of the object shown below

You can update the properties for the above objects like below, here i show an example on how you can update the property object “vsm_hostname”

Once you assign all the required parameters to the OVF config, you can import the OVA file using the bwloc cmdlet.

Once the vAPP gets imported, you would need to register the NSX with your vCenter Server

Login to the NSX appliance and under NSX Management Service, select vCenter server, click on edit and and register the vCenter server.

Next log out and login to the vSphere webclient and you would see that NSX is registered with your vCenter server.

Also note that the above steps are also possible via the NSX API, here is a small extract on the webrequest which needs to be passed to configure this via the official NSX API Guide, this can be done via Invoke-WebRequest cmdlet.

First and foremost i would like to thank Chris Wahl for posting some excellent stuff on how to access the NSX API’s using powershell, Chris Wahl GIT HUB Code, Create NSX 3-Tier Application i used a similar way as he had posted on his blog to access the API via powershell.

Next i would like to thank Timo Sugliani for his NSX Scripts, these examples are excellent, we have everything covered which uses the GET method to access the API’s

Using the sample code which is posted in their blogs i was able to create a query to register the vcenter connection.

Once you establish the connection, you would be able to see the vcenter registered with nsx.

You can also access the information on the registered vcenter using a GET method mentioned in the API guide.

This would lead you to the following output

I hope you enjoyed this blog post and found the information useful. in the next posts we would look into how you would create a “Controller Cluster”, install VIBs (vSphere Infrastructure bundles) onto the Host Clusters and other components to get ready and start using NSX, and we would be using more of automation in these posts too :).
