Thanks for the help. I finally figured out the issue. Apparently server 2016 needed an updated driver for the RAID controller. I downloaded the driver and put it on a USB stick and at the "where do you want to install Windows" screen I loaded that driver and immediately was able to see all of my RAID drives. So I started over with the three drive setup just to see if it may work and I set my two data drives to raid one mirror and did nothing with the OS drive other than set it to Non RAID. I started installation again, loaded the driver and two drives appeared one was my 500 GB OS drive and the other one of the two terabyte data drives. So apparently this controller will do a mix of RAID and NON-RAID drives simultaneously.
This is now set up and working exactly as I wanted it to but I have hopefully a final question. Before I deploy is there any way for me to verify the mirrored drive is working correctly? We do an off-site backup as well but I would still like to at least know that if one of these drives should fail the other is ready to go. Also, the documentation is a bit vague as far as the process and the event of a failure.. if one of these mirror drives fails will it continue to operate without any human help? Since it is set to raid and mirrored.. if one of these drives fails will it still boot or will it catch it as "hey I'm set to raid 1 and there's only one drive functioning so I'm just not going to boot?
I basically understand what you needed, so you need the data drives to be in RAID1.
Can you let me know more about the server, how many total drive you have in the server? 2? What RAID controller do you have in the server? If you only have 2 drives, then you can only set 1 RAID1 VD. Though, you can partition the VD into 2 in the RAID configuration. You can configure the VD partition size.
There is no best way do setting up the RAID, rather to be what is the preferred way. That would be either. I'm most prefer from Lifecycle. RAID configuration would best left the settings at default.
The 500gb is the OS drive and the 2TB drives are the Data drives. If I decided to mirror the OS drive as well would I go about it the same way and would having two arrays impact performance at all?
Actually that didn't work because I was unable to see any hard drives when trying to install windows server. I tried the OS drive as a virtual, physical, a regular volume and nothing worked. Is it not possible to have the one drive not in Raid and have the other two secondary drives set for Raid 1 with this controller?
It's not possible to mixed configuration like you intended, Non-RAID drive with a RAID array.
I tried to check on S130, it listed that minimum disk for RAID0 is 2. I was going to request you to try creating a RAID0 with just 1 drive, though, could you try that and let me know if it does work with 1 drive on RAID0. I know other Dell RAID controllers can do it.
Could you try using the Lifecycle controller to install the OS: https://dell.to/2F6capR, though the OS must be a support OS by the server. Else it won't actually install without errors.
Nice job! Well, it's often that the missing driver is the solution. Happy to hear that it works now
Regarding your final question, a RAID works exactly like that if one drive fails it changes its state to degraded but will continue to work until another drive fails.
If you have a hot-spare setup, this one will be used then to replace the failed drive and will be added as the new member. The rebuild will start and mirror back the data.
The new drive will be set up as a global hot-spare again to jump in if any other drive fails.
And as you never know if the RAID will work like expected, you always do the backup.
Please, don't be afraid of using the RAID - it will work as it should.
Thanks for the clarification. And you are exactly right an on-site duplicate is really not a backup when the building burns, floods, or the server is stolen.

I believe I have it figured out. This is how they are appearing in the S130 config utility.
