If you talk to 'Raspberry Pi Ltd.' when you say 'you', you are simply in the wrong place. Even Eben Upton himself has stated they won't do and invest in SATA anymore (with Pi5 etc). I know you can do RAID with 2 HDDs both their own PSU and USB-SATA convertor chips, but then you have like a Christmas tree as I always tend to describe that. On the serving end RJ45 Gigabit IP network. Modern redundancy is on IP level I would say.GE,
Thanks for all your resposes.
The reason, why I need HW RAID is due to EXSi...
Why EXSi?... Don't have to time to study "how to" in Proxmos... And it's more comfortable and user friendly (for me).
I was wondering why it's still not possible.
.What a great deal could be achieved with X1007 and X1004 if HW RAID supported.
I am in IT for several years too and I know that HW raid is not reliable, but same for SW raid...
Perhaps one day RasPi guys provide some changes and surprise us with HAT/s for HW raid.
.
I have some old 6-Intel_SATA + 2-Marvell_SATA motherboard. The Marvell PCI-E connected chip can do 'HW RAID' although it runs BIOS code to at least configure it. And is it some proprietary RAID, I have no clue what the layout is in the 2 disks connected, although I bet with dm-mapper it would be possible to do the same. It is double traffic on the PCI-E, that is a difference.
But of course, you can contact Marvell to buy such a chip, and make a HAT of it as @memjr suggests. Or actually connect a flatcable as it is not attached on top. But maybe the sales guy will point you to Marvell SoCs with SATA build-in, they have Cortex-A72 based chips that are dedicated for storage and not like RPi HW that evolved from STBs and targeted for digital signage.
And both EXSi and Proxmox are commercial solutions that have perfectly working alternatives build-in standard into Linux. It is basically a 5-minute action list to get installed and a get VM up and running in Pi4-8GB.
