Intel SAS Module AXXRMS2AF080

It's an LSI SAS2008: http://ark.intel.com/products/54561/Intel-Integrated-Server-RAID-Module-AXXRMS2AF080

That page also says the module is to be discontinued in the fourth quarter of 2012.

The FreeBSD driver is mfi(4), I think, but there are multiple firmware versions and modes of operation that complicate things. Not having any of those controllers, I have not paid attention to the details.

If I were looking at those, I'd prefer the PCIE slot versions, which cost about the same but would also work on other motherboards.
 
LSI SAS2008 is supported by the mps(4) driver.

And good to know:

BUGS
This driver is still in development, it has only been tested on the amd64
architecture and has some known shortcomings:
+o No IR (Integrated RAID) support.
+o No userland utility support (e.g. mptutil(8).)
+o Sometimes the driver gets into a state where devices arrive and
depart multiple times, without user intervention.
+o The error recovery code isn't complete.

For me it works great on an IT mode HBA, letting ZFS do all the fancy work.

btw, I saw that 9.1-RELEASE will receive a new driver, maybe more is possible by then.
 
My trouble with a PCI-E controller is that I need to use all slots with other cards, like HBA, SAS controller and etc...
So, maybe this card will work fine with the 9.1 release, isn't it ?
