Example failover scenarios with Windows Server 2019 S2D cluster

In my previous blogpost, I’ve installed and configured a two node virtual S2D cluster with Windows Server 2019 within Hyper-V on my laptop (Windows 10).

Now the full infrastructure is up and running, and the first guest virtual machine is a live, it’s also nice to take a view on some failover scenarios! In the following examples, you can see the high availability and resiliency of a Storage Space Direct (S2D) cluster. It’s realy, realy, realy powerfull and absolute the feature of virtualization!!

The following scenarios I’m going to cover:

  • Live migration virtual machine;
  • Pause a Hyper-V cluster node (drain roles)
    • for maintenance, for example patching, firmware updates or driver updates.
  • Power Off a Hyper-V cluster node
    • For example a power failure or hardware failure

Scenario 1 – Live Migration:

This feature is already present in the previous versions of Hyper-V and it’s realy powerfull to migrate a virtual machine to another Hyper-V host without any downtime!

        

Scenario 2 – Pause a Hyper-V cluster node:

In this scenario I’m going to ‘pause’ a Hyper-V cluster node with the ‘drain roles’ option. This can be for maintenance, for example: Patching, firmware updates, driver updates or just investigate some issues within Windows.

     

     

As you can see, in my two node S2D cluster, we can ‘pause’ one of the Hyper-V cluster nodes and the virtual machine is still up and running!!

Scenario 3 – Power Off a Hyper-V cluster node:

In this scenario I’m going to simulate a power failure or hardware failure, just to ‘Power Off’ on of the Hyper-V cluster nodes! The virtual machine is saved for a couple of seconds, migrated to the other Hyper-V node and started again!

              

With also with a hardware or power failure, the impact and downtime is that much!! Because the power of Storage Spaces Direct (S2D), your workloads are maximum protected and available!!

Wrap Up:

In this blogpost you’ve seen some scenarios with Storage Space Direct (S2D) in Windows Server 2019. Here you can see the high availability and resiliency of a Storage Spaces Direct infrastructure. Realy powerfull and it meets all your needs for your virtualization environment.

WEBINAR: Troubleshooting Microsoft Hyper-V

Altaro_Webinar_Troubleshooting_HyperV

If you’ve been in IT for any length of time, you’ve likely gotten that phone call that you never want to get: Everything is broken! It’s the end of the world! The sky is falling! Your Hyper-V Host or Cluster is broken and you are the person to fix it!

Where do you start?

What are the most common things to look for?

These are exactly some of the questions we’ll be covering in our next webinar, on February 25th, 2016 at 4pm CET / 10am EST!

Microsoft Cloud and Datacenter Management MVPs Didier Van Hoye and Andy Syrewicze will be answering these questions, and will also be sharing some tales from the trenches.

In this webinar you’ll learn Hyper-V troubleshooting basics and solutions to common problems. You’ll also see some Hyper-V oddities that were encountered by Didier and Andy and how these issues were ultimately resolved and with what tools.

It’s one thing to setup and run a virtualization solution. It’s another thing to fix it when it’s broken.

Sign up now to join us on February 25th, 2016 at 4pm CET / 10am EST (30-45mins + live Q&A!) for some tales from the trenches!

WEBINAR: Scripting & Automation in Hyper-V without SCVMM

Webinar_Altaro

Save the date!!

the 10th of december there is a free webinar about automating tasks in your Hyper-V environment without the user of Microsoft System Center Virtual Machine Manager (SCVMM).

This is realy usefull for that customers who don’t have System Center within their environment! Automation and scripting some tasks can save you a lot of time and money!
MVP Thomas Maurer and Technical Evangelist Andrew Syrewicze will present this webinar!
