RAID 0+1:
RAID 0 drives can be mirrored using RAID 1 techniques. Resulting in a RAID 0+1
solution for improved performance plus resiliency.
Features and Benefits
- Drives: Minimum 4, and maximum is 6 or 8, depending on the platform.
Benefits: Optimizes for both fault tolerance and performance, allowing for
-
automatic redundancy. May be simultaneously used with other RAID
levels in an array, and allows for spare disks.
- Drawbacks: Requires twice the available disk space for data redundancy,
the same as RAID level 1.
- Fault Tolerance: Yes.

Spanning (JBOD):
JBOD stands for "Just a Bunch of Disks". Each drive is accessed as if it were on a
standard SCSI host bus adapter. This is useful when a single drive configuration is
needed, but it offers no speed improvement or fault tolerance.
Features and Benefits
Uses: JBOD works best if you have odd sized drives and you want to
-
combine them to make one big drive.
Benefits: JBOD provides the ability to combine odd size drives using all of
-
the capacity of the drives.
- Drawbacks: Decreases performance because of the difficulty in using
drives concurrently.
- Fault Tolerance: Yes.
