SCVMM Fabric Controller Script

We are reaching the holidays, and besides public speaking, I am trying to slow down a bit in order to prepare for the arrival of my baby girl early in January.

However, I haven’t been all that lazy, and in this blog post I would like to share a script with you.

During 2014, I have presented several times on subjects like “management stamp”, “Windows Azure Pack”, “SCVMM” and “Networking”.

All of these subjects have something in common, and that is a proper design of the fabric in SCVMM to leverage the cloud computing characteristics that Azure Pack is bringing to the table.
I have been visiting too many customers and partners over the last months just to see that the design of the fabric in VMM is not scalable or designed in a way that gives some meaning at all.

As a result of this, I had to create a Powershell script that easily could show how it should be designed, based on one criteria: turning SCVMM into a universal fabric controller for all your datacenters and locations.

This means that the relationship between the host groups and the logical networks and network definitions need to be planned carefully.
If you don’t design this properly, you can potentially have no control over where the VMs are deployed. And that is not a good thing.

This is the first version of this script and the plan is to add more and more stuff to it once I have the time.

The script can be found at downloaded here:

Please note that this script should only be executed in an empty SCVMM environment (lab), and you should change the variables to fit your environment.

Once the script has completed, you can add more subnets and link these to the right host groups.

The idea with this version is really just to give you a better understanding of how it should be designed and how you can continue using this design.
