I'm trying to decide between 2 infrastructures.

1. 2 Servers host that point to a NAS

2. 2 Servers that mirror each other with their own local storage.

Infrastructure Requirements: 50 TB of storage, Active Directory, SQL Server, Remote Access, able to supply up to 50 users.

Will buy 2 of these: HP 850519-S01 | neweggbusiness.com

From my research, the 2nd option provides better HA since the 2 Host don't depend on anything but themselves. I'm planning to use VMWare on the host. I'm assuming VMWare can handle this? Meaning can it basically Mirror everything on Host 1 to Host 2?(including storage). So basically all the VM machines, all its files, databases, configs, etc are on both local storages.

If so, is there a guide on how to do this?(I will be learning how to use VMWare). Is it a feature that all VMWare versions include?

If you believe option 2 isn't a good option, may I hear your reasons on why? I was planning on option 1 with my earlier question. Creating a new Infrastructure for my company using Windows Server and FreeNas | Server Fault

But now I'm thinking option 2 is better for us. I appreciate any help/advice from all.

Look at StarWind VSAN 2-nodes hyperconverged solution on VMware here.

It gives a possibility to mirror storage between the hosts and present it as HA datastore to the cluster. Virtual Machines can be deployed then on a top of HA datastore.

Additionally, they have a ready for Production hardware solution - StarWind HyperConverged Appliance.

    I actually was looking into this. Appears that the free version can be used in production. – Derek Welton Apr 16 '18 at 14:15

    If you’ll get more nodes you can look at Ceph as well. – BaronSamedi1958 Apr 24 '18 at 5:12

There is no vmware product that "mirrors" VMs from one host to another. Typically one either uses vSphere Replication which is asynchronous and has a minimum RPO of 5 minutes or a NAS/block device that provides asynchronous and/or synchronous replication (e.g. EMC VNX devices).

    I looked more into vSphere replication and it appears to be what I was needing. Which of the 2 options would you prefer that I mentioned above? – Derek Welton Apr 11 '18 at 18:42

    "There is no vmware product that "mirrors" VMs from one host to another. " (c) ... There is! It's called Fault Tolerance and it's with VMware vSphere for years. pubs.vmware.com/vsphere-4-esx-vcenter/topic/… – BaronSamedi1958 Apr 18 '18 at 14:42
