Intergraph InterRAID-8e Hardware User's Manual page 103

Power Console allows you to create the following RAID levels online.
RAID
Level Description
0 Data divides into blocks and
distributes sequentially among
drives (striping).
1 Data written to one drive is
duplicated on another drive
(mirroring).
3 Disk striping with dedicated parity
drive.
5 Disk striping with distributed
parity.
10 Striping of mirrored array, a
combination of levels 1 and 0 (for
example, by spanning two
contiguous RAID 1 logical drives).
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).
50 RAID Level 50 is a combination of
5 and 0 (for example, by spanning
two contiguous RAID 5 logical
drives).
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.
Application
Data collection from external
sources at very high transfer
rate. Fault tolerance is not
required.
Read-intensive, fault-tolerant
systems.
Non-interactive applications that
process large files sequentially
and require fault tolerance.
High read request rates and low
write request rates, such as
transaction processing, office
automation, and online customer
service requiring fault tolerance.
Data storage that justifies the
100% redundancy of mirrored
arrays and needs the enhanced
I/O performance of striped
arrays.
Non-interactive applications that
process large files sequentially,
requiring fault tolerance and
high speed.
Data that requires highly
reliable storage, high request
rates, and high data transfer
performance.
