Broadcom 3008 SATA/SAS 12G HBA, IT Mode

[OsvaldoP]

Hello everyone!

We all know the rule: don't combine RAID controllers with ZFS.
That's why we've been using Supermicro boards like the H12SSL-NT with its onboard AHCI controller for our setups.

However, our new hardware distributor has recommended a change. They suggest moving to the H12SSL-CT (H13SSL-CT) and using a Broadcom 3008 SATA/SAS 12G HBA, flashed into "IT-Mode." Their reasoning is that Proxmox users specifically prefer this Broadcom HBA setup.

Does anyone have experience with a 'Broadcom 3008 SATA/SAS 12G HBA' in IT-Mode?
What board would you recommend?



Answer from KI to my thread, is this correct?

Community Endorsement: You're absolutely right – the Broadcom 3008 in IT mode is the de facto standard for ZFS builds in the
Proxmox, TrueNAS (formerly FreeNAS), and UnRAID communities. Its reliability, performance, and compatibility are well-proven over many years. 
When you encounter issues or need advice, there's a vast amount of community knowledge available online for this specific setup.

Ist eine gute Idee. Bei diesem Chipsatz kannst du dann auch SAS-Drives anschließen, die - vorausgesetzt, man nimmt sowieso Server-SSD - nicht wirklich teurer, aber schneller sind. Pro Laufwerk 12 GBit statt 6.

Braucht halt einen schnieken x8-Steckplatz, aber dann rennt das Ding. Würde ich mit -16 nehmen, damit man nicht wieder in Bedrängnis kommt und 16 Laufwerke direkt anschließen kann. Wenn weniger reichen, nimm eines mit -8.

Gibts vom Noname und von e.g. LSI.

Hi, and thanks for your response!

It seems the "Broadcom 3008" is often used for ZFS, and IT Mode is working as expected. We will change the board.

Kind regards,
