ZFS Pool over two different controllers problem

[testcb00]

Hi everyone,

I am planing to use my current PC as a home NAS, the hardware is:

Case 6-Bay NAS Case
CPU AMD Ryzen 3 Pro 2200G
MB Asrock B450M Pro4
RAM Samsung 16GB ECC U-DIMM x2
HDD 8TB Toshiba MG06ACA800E x6
NIC Mellanox MNPA19-XTR ConnectX-2 EN 10G NIC on PCIe 2.0 x4
Boot Intel Optane M10 16GB

The current plan is to make a RAIDZ2 array using the 6x 8TB HDD but the MB has only 4 SATA, I have to buy a SAS HBA PCIe Card.
Considered that I may add more HDDs in future, a LSI SAS 9212-4i4e might be a good choice in this case. The HDDs (future) will be stored in a 2U 12-Bay HDD Cage with SAS expander.

But then the problem exists, the HDDs will be controlled by two different controllers, one is MB Chipset and the other is SAS HBA Card.
I would like to know if this configuration will cause problems.

Thank you.

It's not a problem. ZFS is happy with using disks regardless of the SATA controller and disks can be moved between SATA controllers with no concern for position in the system.
