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!!
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.
