Onboard SATA working with dedicated LSA SAS controller

[netall]

So, I've (slowly) started to put together my new Unraid server and I'm not sure what the best approach will be.

Long story, short...

I have the following components:

- i7 7700K

- GA Z270M D3H (6SATA ports) with 16GB RAM

- 2TB Adata Legend 800 NVME (that I plan to use as cache)

- (for now) 4 x 8TB Seagate Ironwolf PRO HDDs - I say "for now" as I plan to extend these and get 8 or 10 HDDs in total

- case (Node 804) and 600W Seasonic Gold PSU

 

Now, I have also ordered a Dell LSA 9207i controller to be able to extend the 6 SATA ports from the MB.

 

Is that OK to mix the usage of SATA ports from the MB and the LSA controller?

I'm asking that because I read various conflicting info - some say it's fine to mix (4 HDDs on MB and 6 HDDs on LSA) while others say that's better to run all disks from similar controllers... the last approach would mean I'd have to buy another LSA controller if I want to have more than 8 HDDs in my array (I only want 1 array with 1 parity disk)!

 

Thanks a lot!

No problem for mix different controller.
