Understanding RAID
RAID is an acronym for Redundant Array of Independent Disks. A RAID system consists of an
array of multiple independent hard disk drives that provide high performance and fault tolerance.
The RAID controller implements several levels of the Berkeley RAID technology. An appropriate
RAID level is selected when the volume sets are defined or created. This decision is based on
disk capacity, data availability (fault tolerance or redundancy) and disk performance.

The RAID controller makes the RAID implementation and the disks physical configuration
transparent to the host operating system. This means that the host operating system drivers and
software utilities are not affected, regardless of the RAID level selected. Correct installation of
the disk array and the controller requires a proper understanding of RAID technology and the
concepts.

RAID 0
RAID 0, also referred to as striping, writes stripes of data across multiple disk drives. RAID 0
does not provide any data redundancy, but does offer the best high-speed data throughput. RAID
0 breaks up data into smaller blocks and then writes a block to each drive in the array. Disk
striping enhances performance because multiple drives are accessed simultaneously; but the
reliability of RAID Level 0 is less than any of its member disk drives due to its lack of
redundancy.
RAID 1
RAID 1 also known as “disk mirroring”, means that data written to one disk drive is
simultaneously written to a second disk drive. Read performance may be enhanced if the array
controller can simultaneously access both members of a mirrored pair. During writes, there will
however, be a minor performance penalty when compared to writing to a single disk as two
writes must occur (one to each disk drive). If one drive fails, all data (and software applications)
is preserved on the other drive. RAID 1 offers extremely high data reliability, but at the cost of
doubling the required data storage capacity.
Qubex User Guide
Page 9
RAID 0+1
RAID 0+1 is a combination of RAID 0 and RAID 1, combining striping with disk mirroring.
RAID Level 0+1 combines the fast performance of Level 0 with the data redundancy of Level 1.
In this configuration, data is distributed across several disk drives, similar to Level 0, which are
then duplicated to another set of drives for data protection.
RAID 3
RAID 3 provides disk striping and data redundancy though the use of a dedicated parity drive.
RAID 3 breaks up data into smaller blocks, calculates parity by performing an exclusive-or
operation on the blocks, and then writes the blocks to all but one drive in the array. The parity
data created during the exclusive-or operation is then written to the remaining drive in the array.
If a drive fails, data on the failed drive can be recovered using the information on the parity drive.
RAID 3 is a good choice for applications that require very fast data transfer rates or large data
transfers.
Qubex User Guide
Page 10
RAID 5
In RAID 5, the parity information is written to all of the drives in the array rather than being
concentrated on a dedicated parity disk. If one drive in the array fails, the parity information can
be used to reconstruct the missing data from that drive. All drives in the array can read and write
data at the same time, greatly increasing the performance of the RAID system.
RAID 6
RAID 6 extends a RAID 5 array by using dual distributed parity. Data and parity is striped at
block level across all member drives, just like in RAID 5. However, two sets of parity are
calculated and written across all the drives. When a disk fails, the data is recovered from the
remaining disks. RAID 6 provides the ultimate level of fault tolerance and can sustain two
simultaneous drive failures without downtime or data loss.
RAID 6 offers a good solution for mission-critical data.
