      What type of Windows licensing do you have? Replication can be affected by that.

        Dell SCv2020

        Do you really need dedicated storage instead of local storage?

        Thanks but I'm not getting into that argument.

        If your SCv2020 is EOL, now is a good time to see if you really need a replacement.

          We have Microsoft Volume Licensing and I haven't looked into weather or not we'd have to purchase "double" or not.. I'm not sure but I thought a backup environment doesn't quite count as production.

            I would say "Hot"=Active.

                hot/warm/standby environment is more what I'm talking about. I do plan to look into the licensing requirements involved. We have Datacenter for the vmware environment.

                  You should be good with datacenter if you have it for every server involved in the scenario.

                    I think I might go ahead and use Veeam's VM replication for a warm site setup.

                      We have a few locations that are all relatively close by

                      That is probably the craziest thing about going through all this hassle and being in the same geographic region. I would seriously consider a colo outside of the area. I mean you do all that work and put in all these expenses and you have an area wide disaster and its potentially gone.
                      Colocation costs are not much more than hosting at your own facility.

                        Could replicate data at the storage controller level:The SCv2020 does have embedded REPL ports specifically for replicating to another SCv2020 via iSCSI - this requires more additional licensing which is fine

                        Does this maintain anything other than crash consistency? Unless the SCv2020 is just automating VMware to do the work, this isn't a failover.

                          Sometimes, it's even less! Not often, but it can happen.

                            Way safer, and probably cheaper.

                              Just an FYI / PSA... if you use Scale HC3, this kind of replication and failover is all included in the base purchase.

                                You need the second site licensed if it is hot, meaning turned on. You do not need anything if it is cold, meaning powered off. Powered off, it's just a backup that's extremely "ready to go".

                                  I think the SCv2020 is EoL so I'm not sure if I would buy a new one or upgrade/buy double or if the SCv2020 can replicate to anything else

                                  Typically replication requires same to same, but not absolutely always.

                                    Could replicate virtual machines at the VMware level but we will need a new vSphere license, setup may be more complex (also fine)

                                    Replication always has to be at this level. You can't safely replicate below it. Storage doesn't have the ability to replicate on its own. If your VMware licensing doesn't allow for replication, that answers all of the questions about the storage lower down the stack. Even if the SC has the ability to replicate, it depends on this feature of VMware to execute it correctly. If you do it without VMware doing the heavy lifting you get inconsistent data. Often looks good in tests, often corrupt in a real life failover.

                                      yeah that would be preferred but we likely won't be able to get our company owners to spend that much money. Setting up a minimal warm site in our other building would be much cheaper/easier.

                                        ok that's good to know. I don't doubt you, but do you know where this info is explicitly stated by MS? I'd like to have it on hand. I may just have to dig through the licensing ToS or something.

                                          I think only cold gets away with no licensing.

                                            How are you planning on handling the IP change - I'm assuming each building is in a different IP range, so routing will become an issue - just another piece of the puzzle.
