NVRAID supports the following types of RAID arrays:
RAID 0: RAID 0 defines a disk striping scheme that improves disk read and
writes 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.
Spanning (JBOD): JBOD provides a method for combining drives of different
sizes in to one large disk.

RAID 0:
The controller "stripes" data across
multiple drives in a RAID 0 array
system. It breaks up a large file into
smaller blocks and performs disk
reads and writes across multiple
drives in parallel. The size of each
block is determined by the strip size
parameter, which you set during the
creation of the RAID set based on the
system environment. This technique
reduces overall disk access time and
offers high bandwidth.
Features and Benefits
Drives: Minimum 1, and maximum is up to 6 or 8. Depending on the
-
platform.
Uses: Intended for non-critical data requiring high data throughput, or
-
any environment that does not require fault tolerance.
Benefits: provides increased data throughput, especially for large files.
-
No capacity loss penalty for parity.
Drawbacks: Does not deliver any fault tolerance. If any drive in the
-
array fails, all data is lost.
Fault Tolerance: No.
