If you only need 3 Gbps SAS/SATA, there's the SuperMicro AOC-SAS-L4i.  It
uses the older LSI1068 chipset, so it's limited to 2 TB harddrives:
http://www.supermicro.com/products/accessories/addon/AOC-USAS-L4i_R.cfm

You could always check if there's an IT-mode firmware for the 921204i4e
card available on the LSI website, and flash that onto the card.  That
"disables"/removes the RAID functionality from the card, turning it into
just an HBA.

Karl,

LSI 9212-4i4e will be good.

You can flash it with the IT Firmware and there are no raid at all.

Subject: [zfs-discuss] SAS HBA's with No Raid

Hi,

I'm thinking of getting LSI 9212-4i4e(4 internal and 4 external ports) 
to replace a SUN Storagetek raid card.

The StorageTek raid card seems to want to have it's drives initialized 
and volumes created on it before they are presented to zfs. I can't find 
a way of telling it just to be an HBA.

I'd prefer to have the ability to move the sas/sata drives to another 
system and has the sas/sata controller read the drives without if there 
a problem with the card.

Is it possible to disable the raid on an LSI 9212-4i4e and have the 
drives read by a simple sas/sata card? I'm open to other brands but I 
need internal and external ports.

Thanks
Karl

That card looks like it is based on the SAS2008 controller, which
means that you need to locate the latest IT (Initiator Target) Mode
firmware for it, and use sas2flash (If I recall correctly) off a
bootable USB stick or similar to flash the controller with that
firmware.

Here is a guide that explains how to flash a LSI2008 that is on-board
on a motherboard; adapt to your situation as needed:
