Enhanced JBOD
Using Enhanced JBOD, you can create a RAID set using a single drive. The resulting
RAID set doesn’t gain the performance or data protection of the other RAID levels, but
it does benefit from the data caching and battery backup provided by the RAID card.
An enhanced JBOD set can also be migrated to other RAID sets or moved to another
computer that has a Mac Pro or Xserve RAID Card installed.
