The higher end LSI RAID products are a bit different.
I expect that other LSI SAS 6Gb/s HBA's would closely resemble the above if you run into something different, please let me know. It has been a very pleasant and flexible controller to work with, as we use them with ESXi in -IR mode as well. A "dmesg | grep mps" would show something like:Īnd so far, things like hot adding a drive seem to work fine. Within FreeBSD, that'll probe as a controller serviced by the mps driver, and the drives will appear as normal "daX" devices and appear in "camcontrol devlist", so pretty straightforward pleasure there. You can look under SAS Topology at your attached disks, but really there's not a whole lot to be seen here in IT mode. Shows you the adapter type and firmware revision. You can hit control-C during that to get to the card configuration utility. Directly attached drives look just about the same, just fewer of them: This is the BIOS probe of an M1015 in IT mode with 8 drives attached via a single SFF8087 and an LSI SAS expander (Supermicro 24-drive SAS backplane). These cards often come without brackets or with a low-profile bracket to fit into 2U rackmount servers. If you get an M1015 and crossflash it to IT mode, you end up with one of the best HBA controllers available for FreeNAS, in my opinion.

If you don't, then it is under the "mfi" driver and it is a RAID card. It is important to crossflash this card! If you do, it works under the "mps" driver, and it becomes a plain HBA.
The card consumes around 10 watts and should have at least some airflow in order to maintain proper cooling. Two SFF8087 connectors provide up to 8 SAS/SATA channels directly via breakout cables, or, if a compatible SAS expander is used, possibly many more SAS/SATA channels. You don't want to run that, you instead want to crossflash it to be an LSI 9211-8i (also known as LSI SAS2008) in IT mode, making it a basic SAS/SATA HBA card. This card comes by default with IBM's version of the LSI RAID firmware on it. It is possible to crossflash these cards to be a generic LSI SAS1068E card, but the silicon is still capped at 2TB drives.Ī favored card in the FreeNAS community is the IBM ServeRAID M1015, a budget RAID card that can be found inexpensively (~$75) on eBay. such controllers include the IBM ServeRAID BR10i and Intel RAID Controller SASUC8I (LSI SAS3082E-R/LSI SAS1068E chipset) and are driven in FreeBSD by the LSI Logic Fusion-MPT SCSI driver ("mpt").

If you are considering buying one, don't, unless you're getting it for $10 or free or something like that.

If you have an older controller of some sort, one that doesn't do SATA-III, you may need some other drivers and you will also be limited to no more than 2TB drives. Most of the current RAID cards seem to be driven by the LSI Logic MegaRAID SAS driver ("mfi") which comes with some significant caveats, including being unable to see your drives via the FreeBSD CAM subsystem or access diagnostics via SMART, and all maintenance and management must be done via the "mfiutil" tool or via the BIOS. The HBA cards I've seen are most often driven by the LSI Logic Fusion-MPT2 SAS driver in FreeBSD ("mps") but older ones may be driven by the LSI Logic Fusion-MPT SCSI driver ("mpt"). In general, a HBA is probably a better choice than a RAID card. They make HBA ("Host Bus Adapter") and RAID cards. See this linked article: What's all the noise about HBAs, and why can't I use a RAID controller?
Any use of "virtual drives" or one-drive RAID0 JBOD modes likely involves the controller writing its own proprietary configuration to the drive and then that means that if you ever need to switch controllers, you're going to have extra special trouble because you need to copy the data off the old drive, not just move the old drive to a new SATA controller port. ZFS and FreeNAS work best when the drive is managed directly by FreeNAS, including having SMART data available from the drive. ZFS users on FreeNAS should avoid using hardware RAID cards. If you're confused, it is probably understandable. A recent post prompted me to think, there's a lot of confusion regarding LSI HBA/RAID cards.
