There's at least a FreeBSD download available for this HBA, the STORCLI = utility, but no driver. However the specifications, as well as the product brief PDF file, = mention FreeBSD support... CC'ing Sreekanth & Kashyap from Broadcom, feel free if you have any info = ! Trying to decide whether or not I build my whole new 3-nodes storage = infrastructure upon these PCI-E 4.0 adapters, or if I go with the = already widely approved SAS3008... Thank you again ! Kind regards, Ben
