Real Time Replication and Failover for VMware

It seems VMware vSphere Essentials has vSphere vMotion, but can I use it without shared storage or a VSA?
good question - @scottalanmiller ?
-
@DustinB3403 But what do you I use keep the VM replicated on both hosts?

Without VSA or shared storage, you can't.
-
a Virtual SAN.
To keep them replicate (and running I'm assuming you mean) you'd also need additional windows licensing.
-
@DustinB3403 Doesn't my data-center licence on each host cover this?
-
@Dashrender What about if I had Hyper V or Xen?
-
@anonymous I know hyper-v will allow you to replicate every minute. (I do that)

@brianlittlejohn just paged everyone on mangolassi.it to read this topic... HAHA
-
@brianlittlejohn And when you lose a host, no problem?
-
@DustinB3403 How did I do that?
-
@brianlittlejohn No, I am asking if you have ever lost a host, and had the systems stay up?
-
@anonymous You will have downtime until the vm boots on the other host. Not to mention the loss of a minute or two of data.

Without shared storage or VSA, you cant have live failover, I don't think.

@DustinB3403 VMware is already installed. They have data center licencing on both hosts. VMware is Essential Plus.
You'll be reinstalling either way, though, right? No matter what licensing they have paid for, that's technical debt. Is there any reason to keep it? Even if VMware is free, I'm not aware of there being any value to keeping it except for "it's already there" but since you need to reinstall for your clustering, that does not appear to apply here.

Nope, because when the one unit dies, the data is inaccessible and the other host has no means to grab it once it is already offline.

In order to enable share or VSA storage.

Ideally they want to use all local storage.
You should have Storage vMotion that will let you do this. But that is useless once one of the hosts as failed.

Veeam will do replication and failover, if you have that. That's probably the cheapest and simplest solution for a 2 host setup.
