Description

OftenOn is my latest project to spin up a 5-node multi-subnet Availability Group on SQL Server 2012 and Windows Server 2012 with one command. How? Through Hyper-V, Desired State Configuration, the Lability PowerShell module, and an immense amount of work.

Building the OftenOn Lab

It takes time on the first run to download about 10GB of Evaluation ISOs from Microsoft. After this though each time the lab is destroyed and competely recreated takes 45-60 minutes. You’ll know it’s done when all the VMs go to the login screen.

Then remote in yourself! Remote Desktop from your machine should work to the short computer names (e.g. CHDC01) via IPv6 but it may not work on some configurations.

The VMs built are as follows:

The C1 cluster has an Availability Group (AG1), a listener (AG1L), and a database (DummyAG1). It’s all sync’d to Dallas and ready to failover for your testing!

All VMs have WMF 5.1 installed. There’s a couple resources (like SQL patches and the .NET 4.7.2 updater) on \CHDC01\Resources. Those aren’t installed everywhere because that’s part of the fun of the lab - exploring various issues with and without them. It’s also loaded with all my other PowerShell modules.
