I have 2 nodes (Dell R720XD's) with 8TB (in RAID 6) internal storage. I also have 2 Dell MD6300i ISCSI's (30TB in RAID 6).

I am looking to buy a VSphere license, and I have the option to have with or without VSA. Does anyone know what (if any) advantage there would be to getting the VSA license? It seems to be fairly limited with a 2 node setup, and the price is an additional $1750.

It appears you have what they are calling "traditional shared storage" (i.e. storage external to the servers that can be seen by both) and the target for VSA is folks who want to avoid that. It allows you to share internal storage among the nodes based on the diagram at this link:

Here we do Fibre SAN and don't have VSA. Any guest you build would have to be on the "traditional shared storage" rather than internal drives to be allowed to fail over automatically. We do have 1 guest on internal drives but it is purely a sandbox test setup so it can go down. Even if on internal drives it can be migrated from one node to the other - it just moves from internal on one to internal on the other. All of our other guests use the SAN storage that both nodes see at the same time.
