Satish,

Yes, that card support 'both'. You have to flash the IR firmware (IT Firmware = JBOD only) and then you are able to create RAID1 sets in the BIOS of the card and any ununsed disks will be seen by the OS as 'jbod'

Kind regards,

both RAID & JBOD mode together so i can do RAID-1 on OS disk and other
disk for JBOD
