Proxmox with TrueNAS VM using Epyc 7002 CPU?

[abishur]

I was looking to get the supermicro H12DSi-N6 motherboard along with an Epyc 7002 series CPU and was going to install Proxmox on it then set up a VM for TrueNAS and pass my hard drives into it. However, can I use the built-in SAS ports on the motherboard to accomplish this?

So far I've had independent SAS chipsets or cards that I would flash for IT mode and could completely pass into my TrueNAS VM to have full control over the drives, but my understanding is the 7002 CPUs have the controller built into the CPU so is it even possible to pass that into the VM or would it be wiser to get a SAS card that I could flash to IT mode instead?

What do the IOMMU groups of the motherboard look like? EPYC has lots of PCIe lanes from the CPU but it depends on the motherboard and BIOS whether the SAS controller of the motherboard can be passed through (alone in a IOMMU group) and whether the SAS controller resets properly (otherwise it won't function in the VM). Try to find out if someone on the internet has already done it successfully with the same motherboard and/or the same SAS controller.

EDIT: My apologies for not being helpful and restating what you already investigated and are actually doing already. Let me know if you want me to remove this post.

Like I said, the Epyc CPUs have the controller built into the CPU is my understanding, no external controller on the motherboard at all. I was asking here specifically to find out if someone had already done it successfully
