Hi gang!

I have 2x SuperMicro AOC controllers (8 SATA drives on each). The problem is, they don't seem to support larger than 2TB drives

Would these controllers replace them (vis a vis, do they have support under unRAID):

 

LSI Internal SAS SATA 9211-8i 6Gbps 8 Ports HBA PCI-E RAID Controller Card

 

These appear to support up to 6TB and are available on eBay for < $100.

Any advice is appreciated

See search tips in my sig. Searching the forum for "9211" gives 10 pages of results.

Thanks, you're right the search is not very intuitive!

Even after that though I'm still unsure, LOL.

 

It seems there's a lot of back and forth with very little definitive answer (that I could see).

I was hoping someone could idiot-proof it for me

 

Thanks!

Your signature lists 2x AOC-SAS2LP-MV8. Are these the ones you're referring to? I also run 2x of them and have numerous 3TB drives running fine.

PCIe AOC-SASLP-MV8 and PCI-x AOC-SAT2-MV8 both support > 2TB drives for me don't have a AOC-SAS2LP-MV8 but BrianAz has confirmed >2TB with it.  So if you are using any of those three controllers you should be able to use > 2TB drives on them as data drives.  They may not support booting from > 2TB drives however.

I am using both of those controllers, but when I put on a drive > 2TB unRAID will show only 2.2TB as the size.

Are you on unraid v6?

Yup, 6.1.4

Not sure what to tell you.  My backup server has 4TB Seagate drives and has a SASLP-MV8 on it controlling 2 of the 6 drives in my N54L.  unRAID version on that box is 6.1.2.

Yeah I know it's weird.... both my controllers are identified thusly:

 

01:00.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS (rev 08)

That is NOT a SASLP-MV8 it might be a SAS2LP-MV8 but I don't think so.  The SAS1068E chip does not support > 2TB drives - at least on posts I've seen here.  My guess is it is a Dell 6i.

Maybe a long shot, but my 3Ware card has an option called Auto Carving.

 

It was enabled by default and it splits down drives greater than 2TB into smaller volumes.

 

The result was that my 4TB drives were being seen as 2.2TB and 1.8TB.

 

Disabling it in the BIOS resulted in my drives full volume being reported.

 

You haven't mentioned that I know, but maybe worth a look.

A LSI 1068 is built in to my MB and it definitely does not support drives over 2.2TB. For larger drives you need a LSI 2008 chip, as used in the 9211 card and Dell 310.
