Hyper-V High availability? or only VMware

But even that seems really undesirable (RAID 6 that is) because of the performance penalties - I 'feel' like a single server would be better in general in that case with RAID 10 Spinning Rust, or RAID 5 SSD.
Depends on the workload. Most SMB workloads are perfectly fine on RAID 6. Remember you two arrays here, not just one, so your getting some performance from each, but you do have write overhead of the network.

I wonder if @scottalanmiller would still recommend OBR 10 instead of RAID 6 for use with Starwind?
All depends on the workload. In this case you would normally gravitate towards OBR6 unless you need the speed of OBR10 rather than looking primarily at reliability.

but my boss wants the OS to be failover-able.
Did you explain to him that the OS failing over could DIRECTLY undermine the ability to meet the business need of keeping the files available? OS failing over is a fallback for when your file server fails to fall over, it's not his goal.
Sounds like he is leading with "proximate" needs rather than "goal" needs.

Currently both A and B are on different physical servers but B still has some files on A server. When server B goes down, it cause DB corruption.
We should address this and fix why the database is corrupting as a good starting point.

At this point of the conversation, I will restate. You need to just step back and start over.
Hire a new consultant, get a proper idea of what things will take to get done and move forward then. -

Hire a new consultant, get a proper idea of what things will take to get done and move forward then.I am rethinking what exactly that need to be done. As SAM has mentioned:

Maybe I am too deep and trying to create a system that is not the solution for us.

@LAH3385 might be good to start a thread and try to determine what your needs are before going down the path of technology. By the time you were asking this question, you were already in pretty deep assuming certain products, product categories and platform HA. We should start with a business needs analysis, use that to set goals and then use the goals to select technology approaches.
