IBM ServeRAID M1215 (equivalent to LSI 9340-8i) SAS controller card that we modified for use with ZFS. They have been cross-flashed to Avago / LSI 9300-8i IT (Initiator Target) firmware version P16 (specifically 16.00.12.00). I also flashed the LSI/Avago MPTSAS3 BIOS ROM version 08.37.00.00 and UEFI 18.00.00.00 so that it is easier to access the controller's ROM without booting an OS. LSI Avago IT mode firmware version P16 (16.00.12.00) MPTSAS3 BIOS ROM flashed version 08.37.00.00 MPTSAS3 UEFI ROM flashed version 18.00.00.00 Original SAS address preserved in flash Original Board Tracer Number preserved in flash Original Board Assembly preserved in flash These are based on the LSI SAS3008 SAS-3 controller chipset and support PCI-E 3.0 specifications with x8 lanes. The controller has 2 SFF-8643 connectors, each carrying 4x 12Gbps SAS lanes. You will need a compatible cable to connect these to your hard drives or a backplane.
