Power Console allows you to create the following RAID levels online.
RAID
Level
Description
Application
Drives
Needed
0
Data divides into blocks and
distributes sequentially among
drives (striping).
Data collection from external
sources at very high transfer
rate. Fault tolerance is not
required.
One to
eight
1
Data written to one drive is
duplicated on another drive
(mirroring).
Read-intensive, fault-tolerant
systems.
Two
3
Disk striping with dedicated parity
drive.
Non-interactive applications that
process large files sequentially
and require fault tolerance.
three to
eight
5
Disk striping with distributed
parity.
High read request rates and low
write request rates, such as
transaction processing, office
automation, and online customer
service requiring fault tolerance.
three to
eight
10
Striping of mirrored array, a
combination of levels 1 and 0 (for
example, by spanning two
contiguous RAID 1 logical drives).
Data storage that justifies the
100% redundancy of mirrored
arrays and needs the enhanced
I/O performance of striped
arrays.
Four, Six
or Eight
30
Striping of two or more RAID 3
arrays. RAID Level 30 is a
combination of 3 and 0 (for
example, by spanning two
contiguous RAID 3 logical drives).
Non-interactive applications that
process large files sequentially,
requiring fault tolerance and
high speed.
At least
six
50
RAID Level 50 is a combination of
5 and 0 (for example, by spanning
two contiguous RAID 5 logical
drives).
Data that requires highly
reliable storage, high request
rates, and high data transfer
performance.
At least
six
NOTE
Look at the Power Console main menu to determine if the physical drives are in “Ready”
state. Verify before you start the create array process.
To create an array:
1. From Adapter in the top menu bar of the Power Console main menu, select
Configuration.
2. Select Custom Configuration. Power Console will scan the configuration and display a
dialog similar to the following.
