ESX cluster

[elijah1]

Silly question.

What's the point of having 2 ESX hosts clustered on esx level without having vmotion?

If you have HA, for fail over. If no HA, no DRS, not vmotion, no benefit.

We have VMWare HA license, so which kinf\d of failover it allows - automatical failover of VMs form one host to another?

HA monitors heartbeat of your ESX Hosts. If heartbeat is lost, VM's that are running on the host that fails will be powered off then powered back onto the other host in the cluster assuming there are no resource violations and you have shared storage. If no shared storage don't bother to use HA, it won't work.

So, if you have HA and shared storge, create a cluster and use it, in my opinon.

Here's a couple other things worth looking into

Here is some nice information about the eternal question : OS-level clustering or the same on Vmware level:

I really like this one.
