Sean, thanks for your input. I’m not quite sure what your recommendation is,
though.
Also, does anyone else have approaches not covered yet? Comments to pro or con ?

Too bad, the Essentials Plus package would allow you to create a vSphere HA
cluster. That would probably provide the HA you were looking for, as long as
100% uptime wasn't a requirement.
To support clustering in a virtual environment you'd need to present the shared
disks as RDMs (Raw Device Mappings). This is typically done using iSCSI with a
software initiator on the guest OS. That would require your SAN support iSCSI.
Can also be accomplished using HBAs on the host.
There is a ton of information out there on how to setup a virtual Windows
Cluster, as well as a lot of Pros/Cons that should be reviewed.
I'm not sure I agree with your comments regarding the difficulty in resizing a
virtual disk, or it being any more difficult to move. Even without features
like storage vMotion, a VMDK is typically more portable than a LUN on most
storage platforms.

Hello All,
My boss requested that I make our File Server highly available.
We currently have a physical server running Windows 2012, with shares published
using DFS. The server has large quantities of DAS, some of which are shared
primarily for IT dept use, and is connected to an 8 TB SAN which has the main,
most used, share.
I know that I can go out and purchase another physical file server and connect
it to the same SAN LUN and finish the requirement.
Besides acting as a file server, this server also serves WSUS and WDS.
However, I’m thinking that it may make more sense to create 2 VMs on 2 existing
separate physical hosts and create a cluster . The question is how I’d attach
the SAN LUN to the virtual cluster. Would I need to create a virtual disk on
the SAN, attach it to the cluster and copy the contents of the shares into that
virtual disk? The downside of a virtual disk is that once created, it’s
difficult to resize if necessary, and unwieldy to copy/move to a new SAN that
we will certainly need to get eventually.
Any input for either scenario welcome, and I certainly will embrance any new
ideas of how to accomplish this task.
