Well that was fun.
I was running 2 “Servers” for home use, one being a Gen 10 HP Microserver, and the other an old desktop i5 6500 system (see here).

Then I obtained a Dell R730 rackmount, with 4x 4TB SATA drives.
Those drives ended up in the HP.
But I found that when viewing things off Plex (server was on the i5) where the media was on the HP, it did not always work so well, even when using the dual NIC’s.
So I did this……………
Moved all the data around.
Took the 4x 4TB drives and put into the i5. We now have 16TB storage – but slight issue…. motherboard only has 4 SATA ports, and I need 5, because the system has to boot off something. (Yeah I could use one of the 4TB as boot as well, but wheres the geek in that)

Luckily, my work had decomm’ed an IBM server a couple years ago, and I still had parts from it sitting in a draw in the office. Boom. 2x LSI HBA cards.
Took one home, threw that into the i5.
After a little bit of fiddling in the LSI BIOS, IT FREAKING ALL WORKED!!!!
Didnt have to flash the LSI as I was seeing online as common thing to have to do to get it usable as an extra SATA controller.

So, now I have 16TB storage active in my server, with another 8 on standby (will need a PSU with more SATA connectors).

And I have shutdown the HP, and will sell it as they tend to go for a decent amount. Fantastic as a NAS.
Xmas entertainment sorted 😀
