I'm looking at an IBM M1015 and reflashing for extra capability and seen this neat little list of options:
LSI9211-IT = Straight pass through no RAID, best for ZFS file system etc
LSI9211-IR = Pass through as in IT mode, but you also have RAID options (RAID 0, RAID 1, RAID 1e and RAID 10), better for RAID 0 Windows boot SSDs etc, and possibly run Software RAID 5 on the other drives.
LSI9240 = default mode, only really useful feature this mode has is RAID1/ RAID 10, drives have to be set to JBOD (single) or RAID to be seen by OS, can be annoying when adding removing drives often.
Seeing as I am looking to run arrays native to the card AND a Windows software RAID, I will most likely crossflash one to LSI9211-IR, but, in the future if I want to use R5 on the card and get the upgrade license to support that, does anyone know if that will affect the support of the software RAID/passthrough/JBOD?
