this post is pretty much a bunch of Resources links.
Four of my resources and a quote from me in the .sig. Trying to curry favor? Haha.

I'll stop linking your content when you quit writing such good stuff. And the 40GbE quote seemed extra-relevant for this thread. ;)Four of my resources and a quote from me in the .sig. Trying to curry favor? Haha.
1) Set up patrol reads to verify the RAID1 disks
2) Set up a script to notify you if sas2ircu picks up on any problems
3) Add a fourth SSD to the mix as a spare in case any of the first three fail
like why one has to know and do all this just to setup shared storage
one should NOT need to know all this or get this indepth

Mentioned production because this will not be some home lab stuffs, will be running mission critical stuffs
from what i know, one can just ignore the RAID controller and it will leave things alone
but now am hearing i should replace with HBA
What if i do single boot drive? I mean if that fails one will just install another OS right?For example, your R730XD has an option for a rear 2x2.5" internal swap bay. If you leave that in place, you could cable those two bays into the H730P and set it up as a hardware-mirrored boot pool. Put an HBA330 into one of the PCIe x8 slots and cable the front 24 bays into that. You'll need to use another x8 slot for your 40GbE card
Can you explain this part?I'd even suggest buying into the 4x PCIe U.2 hotswap option which means consuming an x16 slot for the adaptor card. Then you can stuff a bunch of Optane devices up front to accelerate your NFS sync writes
What about R740xd then? if that will help refrain from too much customizations?(The R730XD is a really nice platform to build on, if anyone else was wondering.)
Sure, it's no big deal. It's also not expensive to add a second one, so you typically see that in enterprise deployments.What if i do single boot drive? I mean if that fails one will just install another OS right?
You're not wrong, but there's more to reliability than age. It's a sort of low-impact, low-cost thing that can nudge uptime up a bit. Of course, you can also go with crazier setups, but few people do.RAID on boot drives of same age, what advantage really?
With good SSDs, not very likely.What is probability of boot drive failing? especially using an 870 EVO SSD?
Better, but not that much better. The only major improvements are better CPUs (probably not a major limitation) and support for more than 4x bays with PCIe SSDs in some models. Cost is much higher. The HBA/RAID controller situation is the exact same, Gen13 and Gen14 use the same proprietary form factor for the embedded controller.What about R740xd then? if that will explain refrain from too much customizations?
I can drive pretty fast/well compared to most driversDo you have Mario Andretti's driving skills?
If not, why do you drive a car (assuming you do)?
There are all sorts of things that are discussed, some of which are truly important, some of which are less important for the average use case.

If using sync writes, you'd typically an SLOG to get some semblance of performance. For a while now, NVMe is the way to go and the R730XD in some configurations, has four bays that can take PCIe SSDs.What about this?
Optane drives to speed up NFS writes? How do i put this up front?
Not sure i understand this setup
You are right it says support up to 4 Express Flash NVMe PCIe SSDsIf using sync writes, you'd typically an SLOG to get some semblance of performance. For a while now, NVMe is the way to go and the R730XD in some configurations, has four bays that can take PCIe SSDs.
