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 Advantages Drawbacks # Hard
Disks
Fault
Tolerance
RAID 0 Non-critical data
requiring high
performance.
High data throughput.
No fault tolerance. multiple None
RAID 1 Small databases or any
other small capacity
environment requiring
fault tolerance.
100% data
redundancy.
Requires 2 drives for
the storage space of 1
drive.
2 Yes
RAID 0+1 Critical data requiring
high performance.
Optimized for both
100% data
redundancy and
performance.
Allows spare disks.
Requires 2 drives for
the storage space of 1
drive—the same as
RAID level 1.
4+ Yes
JBOD Combining odd size
drives into one big drive
Combines and uses
the capacity of odd
size drives.
Decreases
performance because
of the difficulty in
using drives
concurrently or to
optimize drives for
different uses.
