Configuring Arrays
Organize the physical disk drives in arrays after the drives are con-
nected to MegaRAID IDE. Each array can consist of one to two
physical disk drives.
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 toler-
ance. Use RAID 1 or mirror configuration to attain this objective.
Maximizing Drive Performance
You can optimize drive performance by using striping. Select
RAID 0 or striping to configure an array for optimal performance.
Assigning RAID Levels
Only one RAID level can be assigned to each array. The drives
required per RAID level is:
