JBOD = Just a Bunch of Disks

JBOD refers to an unconfigured disk attached to a RAID controller

• No fault tolerance

All AMCC 3ware RAID controllers incorporate onboard processors to deliver true hardware RAID. Software RAID schemes use the system’s processor, exploit host memory, compromise reliability and potentially rob the system of as much as 60% of its CPU cycles just to process RAID calculations.
