Configuring MegaRAID IDE
This section explains how to:
! configure MegaRAID IDE and arrays
! assign RAID levels
! plan the array configuration
! optimize storage
! use the MegaRAID IDE Setup Utility
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.
