I got the S300 with a used R210-II; it actually is a PCIe card with an SFF-8484 connector with a fanout cable for the drives. I'll probably just pull the card from this machine and use the onboard SATA, since the drives are SATA anyway. (I guess the previous owner got the S300 for softraid.)

This is probably worth trying, thanks.

I don't believe the controller will automatically export unconfigured drives as single drive units. LSI makes 2 different versions of firmware for the unbranded controllers, IR mode for RAID and IT mode for HBA, but it's not possible/easy to flash them to the Dell branded controllers. Create RAID0 single drive units on each disk and it should export.
Dell S300 controller
Does anyone know if the Dell PERC S300 controller will work under OpenBSD as a non-RAID SAS HBA? It has an LSI SAS 1068e, but I didn't know if they did something to make it not work as an HBA. Thanks.
