      It seems VMware vSphere Essentials has vSphere vMotion, but can I use it without shared storage or a VSA?

      Ideally they want to use all local storage.

        If and only if you have the Essentials Plus are you licensed for this. I'm not certain if there is a difference with regards to "having shared storage and not"

        I would assume that it doesn't matter

              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 And when you lose a host, no problem?

                              @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.
