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.

    If you’ll get more nodes you can look at Ceph as well.

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?

    "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/…
