3ware 9000 Series Serial ATA RAID Controller User Guide
JBOD units are not fault tolerant and therefore not recommended for high
availability systems unless additional precautions are taken to prevent system
hangs and data loss.
Hot Spare
A single drive, available online, so that a redundant array can be
automatically rebuilt in case of drive failure.
For additional information about RAID levels, see the article “RAID Primer”
on the 3ware website, at: http://www.3ware.com/products/pdf/

Determining What RAID Level to Use
Select the RAID configuration to use based on the applications to be used on
the system, whether performance or data protection is of primary importance,
and the number of disk drives available for use.
Review the information under “Understanding RAID Concepts and Levels”
on page 8 to determine the type of RAID configuration most appropriate for
your needs and use the tables below to determine what RAID levels are
available, based on your particular controller model and the number of
available drives.
The RAID configurations available to you are determined by the number of
ports on your controller, and the number of drives attached to those ports. You
can configure all drives in one unit, or you can configure multiple units, if you
have enough drives.
