Configuring Arrays
Organize the physical disk drives in arrays after the drives are 
connected to IDE software RAID. And array can consist of one to four 
physical disk drives, depending on the RAID level.
Configuration Strategies
The most important factors in RAID array configuration are drive 
availability (fault tolerance), and drive performance.
Maximizing Drive Availability - You can maximize the drive 
availability by increasing fault tolerance. Use RAID 1 or mirror 
configuration to maximize availability.
Maximizing Drive Performance - You can optimize drive 
performance by using striping. Select RAID 0 or striping to configure an 
array for optimal performance.
Performance and Availability - You can achieve both drive 
performance and availability. Select RAID 10 for this configuration. You 
will need four drives to configure RAID 10.
Assigning RAID Levels
Only one RAID level can be assigned to each array. The drives required 
per RAID level is
