HBA SATA/SAS Controller

The LSI (now known as Broadcom / Avago / ...) are usually the gold standard of HBAs. Highly recommended, and supported.
 
I just spent a lot of time researching this and pretty much came to the same conclusion. I chose the LSI SAS 9207-8i supported by the mps() driver because it's cheaper than what you listed and 12Gb SATA isn't something my spinning disks need. I'll get to test it out tomorrow.

The Marvell based controllers appear to be just not that great (SIIG, StarTech, HighPoint, and... ugh... Syba) with the 88SE9215 and 88SE9235 non-RAID chipsets, based on others experiences, not just on FreeBSD. There also weren't enough PCIe lanes on the cards to support the bandwidth of all the drives at once. LSI's controllers seemed to not have these problems, but were double the cost. You get what you pay for, I suppose.

People seem to like the Silicon Image 3132, but that's only two ports. The JMicron chipsets seem to use PM technology to achieve port density, which is just unacceptable.
 
that's awesome, thank you for the incite. I see the 9200x is listed in the supported hardware, so Ill get one of those.

cheers
 
Read the Backblaze Hard Drive Stats before you decide on the disks.
Make sure that the correct break-out cables for your disks are included when you purchase the controllers (I had to order mine as separate items).

Good point.

I got mine from an old surplus server, free of charge. I have a few other LSI based cards too, all from old servers. Excellent cards on FreeBSD :)

When using SAS to SATA fanout cables, these are directional as to which port goes to the host (controller) and which goes to the target (backplane or drives).
 
I was just trying to figure out why the controllers all say 512 devices supported .. or 250 devices supported .. yet the mini sas connector says it only does 4 devices .. if you plug 1 minisas from your 12 port back-plane .. does it see 4 drives or 12? or do they mean you can only use 4 devices per sas connector if your building a hardware raid on the card?
 
Pleased with the LSI SAS 9207-8i so far. S.M.A.R.T. works through it. (edit) The card runs HOT. Seems like it could use a fan.

Yes, LSI (Broadcom/Avago/...) SAS cards are known for that. As are Mellanox Infiniband cards. That's because they have a lot of IO and CPU horsepower; the better LSI SAS HBAs can saturate the bandwidth of a PCIe slot and pump all that data over SAS, while doing rather complex SCSI operations.
