RAID Arrays

NVRAID supports the following types of RAID arrays described in this section:
RAID 0: RAID 0 defines a disk striping scheme that improves the disk read and write
times for many applications.
RAID 1: RAID 1 defines techniques for mirroring data.
RAID 0+1: RAID 0+1 combines the techniques used in RAID 0 and RAID 1 arrays.
Spanning (JBOD): JBOD provides a method for combining drives of different s i z e s
into one large disk.

Summary of RAID Configurations

Array Uses
RAID 0 Non-critical data
requiring high
performance.
RAID 1 Small databases or any
other small capacity
environment requiring
fault tolerance.
RAID 0+1 Critical data requiring
high performance.
JBOD Combining odd size
drives into one big drive
