RAID Level.
This shows the RAID level of the RAIDset.
To change the RAID level, run the CL1850 Array
Configuration Utility.
The following values are valid for the RAIDset RAID
Level:
JBOD (2)
Just a Bunch of Drives. Fault tolerance is not enabled. This
RAIDset is made up of one device. Does not provide extended data
redundancy, availability or protection, and does not use striping
for performance enhancements.
Good for applications requiring high device capacity. Requires one
and only one device.
RAID0 (3)
A RAIDset using device striping and write-back caching.
Data is spread across many devices, offering faster read/write
performance than a single device. Does not provide extended data
redundancy, availability or protection. Good for applications with
large files needing high I/O performance. Requires a minimum of
two devices.
RAID1 (4)
A RAIDset using device mirroring. Any time data is written to
a device, a duplicate write is also made to a second device. Reading
from multiple devices is usually faster than reading from a single
device. Provides extended data redundancy, availability and
protection. Good for read-intensive applications needing high
availability. Requires a minimum of two devices.
RAID0PLUS1 (5)
A RAIDset where data is striped across devices and duplicated
on an equivalent number of devies. Provides extended data
redundancy, availability and protection. Good for applications
requiring high availability, high performance and capacity.
Requires an even number of devices, and a minimum of four devices.
RAID4 (6)
A RAIDset using device striping, with one device assigned for
parity. Provides extended data redundancy, availability and
protection. Good for applications such as graphics and imaging that
call for writing huge, sequential blocks of data. Requires a minimum
of three devices.
RAID5(7)
A RAIDset using device striping, with parity distributed across
devices. Provides extended data redundancy, availability and
protection. Good for transaction processing, applications requiring
many, small I/O operations scattered randomly and widely across the
devices. Requires a minimum of three devices.
