starting to wonder if running 2 unraid servers on one board might be a good idea

These are really a different class of product.  If you want this much storage in a single POD you're better off to run a single RAID-6 than to try and configure it with 2 UnRAID servers in the same box.

 

But if you did want to do that, you'd have to use 2 separate 24-port RAID controllers (so you could pass each through to a VM); and set up two separate UnRAID VM's ... passing one controller through to each VM.

 

Running a pair of UnRAID VM's under ESXi should work just fine.  But by the time you configure this and buy two 24-port RAID cards to provide the ports you need, it'd likely be both more efficient and less expensive to build 2 independent 24 drive systems.

 

 

Also you increase risk of data loss.. The enclosure is so expensive that is cheaper AND more safe to have two servers.. The only reason I can imagine is that you do not have the space for two...

With that much data and just one or two 2gigs ethernet port to push em out... (not to mention the number of real users at the location), I wonder if it's more reasonable and economical to implement a snapshot-type raid like flexraid or snapraid, than an always-online system like unraid.
