asked on HyperV Failover cluster - general question
Hello experts,
i created my first failovercluster with hyper-v.
i thought, this is just some kind of a container for VMs to switch from one node to the other.
But i noticed, that an additional IP address has been assigned to the cluster. i mean not to the VM i created in this cluster, but to the cluster itself.
so i have these IPs
x.1 NIC on node1.cluster.local
x.2 NIC on node2.cluster.local
x.10 mrbusi.cluster.local
x.50 testvm
can anybody explain to me, what this additional IP is for?
many thanks

"so, i can choose just a service to becom HA and that is bound the "cluster-ip", right?"
That depends on the service.
"that means to make an exchange-server HA i dont have to create a vm as cluster ressource..."
Essentially, though Exchange will want its own IP address (different from the cluster itself).
"...install a third windows server and the exchange on that machine."
I'm not sure what you mean by this, but a two node cluster will be more HA than a standalone server.

i mean, i have my 2 nodes clusterd
N1.cluster.local and N2.cluster.local
i thought, i have to create a VM, thats HA
install a (3rd) Win2008R2 on that, lets name it mail.cluster.local
and install my exchangeserver on that VM
or can i:
install exchange on N1.cluster.local and N2.cluster.local
and (shortened)
tell the cluster to make the exchange-service HA

I see. Yes, either of those scenarios would work depending on what else you want to do with the clustered hosts.
There's certainly more overhead involved in clustering a VM that's running Exchange than in just running Exchange directly on the cluster itself. On the other hand, if the nodes in the cluster are beefy enough and you want to do other work with them, your first scenario would work just fine.

ok, thanks a lot for your help
so, i can choose just a service to becom HA and that is bound the "cluster-ip", right?
that means to make an exchange-server HA i dont have to create a vm as cluster ressource, install a third windows server and the exchange on that machine.
correct?
