JBOD controller

[pettinz]

Hi,
I’m having troubles searching on internet SAS HBA controllers that allow me to configure my hard drives in JBOD mode. I searched for the LSI 9211-8i to be a good card but it is not well explained how to configure it to work in JBOD mode. What I need is that my drives are treated as a singole one, without redundancy, but if a drive fails, it must not compromise the others.

When flashed in IT mode SAS HBA do exactly what you want.
The 9211-8i feels like a 8 port SAS/SATA controller.

I think he's asking for the "jbod" raid where all hdds/ssds are put together to a large logical device, similar to raid 0 but without the striping.
Non-RAID drive architectures - Wikipedia

I'm not sure if braodcom or adaptec have raid controllers that support this raid type.

I'm not sure what goal is here either...
"but if a drive fails, it must not compromise the others"
If some disks are connected into a virtual volume, I expect that a drive failure would compromise the others.

If you're on Windows, have a look at DrivePool (StableBit).

Seconded. Member drives are all directly addressable in the even of other member drive failures. If you don’t duplicate the folders you lose files on the failed member, but the absence of the disk doesn’t impact the files on the remaining drives.
