Learn all about Windows Server 2019 Cluster Sets

Hello. My name is John Marlin.
I am a Program Manager on
the Windows Server Team. This video will give you a brief
introduction into a new feature in
Windows Server 2019 called Cluster Sets. So what is Cluster Sets? Cluster
Sets is a loosely coupled
grouping of Failover Clusters. Combining those clusters together to,
in essence, make one large Cluster. It allows for virtual machine
fluidity across clusters for
balancing and maintenance tasks. It has a self-managed and
dynamically updated single
unified namespace that it uses. And most importantly, Cluster
Sets is all about scale
without the loss of resiliency. So how it work? As you see here,
I have four individual clusters. Creating a Cluster Set will
combine those Clusters together
using that single namespace for
centralized Cluster Set Management. So how does it work with virtual machines? When creating a new virtual machine,
you will specify this unified namespace. Based on minimum memory and CPU criteria
that you have set, Cluster Sets will
deermine the best Cluster to put it on. Repeat the action for any additional
virtual machines that you create. In some cases, high end virtual
machines need to go to a specific
Cluster for whatever reason. This virtual machine, as an
example, could be SQL Server. Specifying a “tag” on a Cluster
allows you to point that new virtual
machine to that specific Cluster. So does it interfere with any
normal clustering operations? The answer is no. Everything will continue to work that
you would traditionally see on a Cluster. Things such as preferred
owners, node isolation, load
balancing within the same cluster, normal failovers, normal failbacks between
individual nodes of the same cluster. All still continue to work as normal. One of the things that it does give
you is the ability to move virtual
machines across the different Clusters. Cluster Sets will keep track
of the location of the clusters
the virtual machines are on. The individual cluster determines
which node it should run on. Cluster Sets is ideal for compute end
of life and let me give you an example. Here, I want to move all the
virtual machines off of a cluster. In this case, Cluster 1 I
am going to decommission. Once they are all moved off, remove that
cluster from within Cluster Sets and, at that point, remove the cluster. Decommission it, repurpose
it for other cluster means, whatever you need to do. So for more information
regarding Cluster Sets, if you are currently not a Windows
Insider, join from the following web
site. https://insider.windows.com. Join up on the Insider Program. Download the latest Windows
Server 2019 Insiders Build. All documentation is available
at http://aka.ms/Cluster_Sets. We even have a hands-on lab on
GitHub that will walk you through creating a Cluster Set,
creating virtual machines, moving virtual machines between
the clusters, all provided for you. And please provide feedback through
the Windows 10 Feedback hub or, if you prefer email,

I hope you give Cluster Sets a try.
