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 sizes
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

Advantages
Drawbacks
High data throughput.
No fault tolerance.
100% data
Requires 2 drives for
redundancy.

Optimized for both

RAID level 1.
Allows spare disks.
