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 perf ormance, allowing for

automatic redundancy. May be simultaneously used with other RAID

lev els in an array, and allows f or spare disks.

- Drawbacks: Requires twice the av ailable disk space f or 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 y ou hav e odd sized driv es and y ou want to

combine them to make one big drive.

- Benefits: JBOD prov ides the ability to combine odd size driv es using all of

the capacity of the driv es.

- Drawbacks: Decreases performance because of the difficulty in using

driv es concurrently.

- Fault Tolerance: Yes.
