i-Sata vs s-Sata vs HBA

[cooling]

Hello, I'm trying to build a new server with this hardware:
- Supermicro X10SRA-F
- Intel Xeon 2695v4
- 4x8GB DDR4 2133 ECC-reg
- 8x8TB Wd RED in RAIDZ-2 configuration
- NIC Intel X520-DA2

I'm not sure how to connect HDD...the Supermicro motherboard has 6 x i-Sata (AHCI) ports and 4 x s-Sata (SCU) ports, but I don't understand the difference (I've already search, but not a lot of luck) between them and if it's safe to connect HDD some to i-Sata and other to s-Sata. I've got also an LSI 9211-8i HBA, that I can use (can it also improve performance respect motherboard ports?)...what you suggest to do?

Thanx in advance.

The SATA ports have two controllers. For FreeNas that does not matter and you can plug into any ports. No need for the HBA, unless you want to use something like ESXI. With that said. I don’t believe that board is a popular FreeNAS board as it is more geared towards a workstation with the onboard sound.

The LGA2011v3 chipsets internally separate the two controllers. For FreeNAS, it makes no difference whatsoever and you can treat them all the same.
