How Do I Do a Custom Configuration?
Custom Configuration gives you full control over the configuration of your
disk drives. With Custom Configuration, you can:
• Select individual disk drives to add to the configuration
• Build multiple arrays
• Configure logical drives individually
• Select a specific RAID level
• Select the write caching method (Write-Thru or Write-Back)
• Set the stripe size
• Set logical drive size by physical or logical capacity
• Add capacity to an existing array
• Assign additional spare drives or unassign existing spare drives
• Enable spanning to create a configuration of larger drive sets
Once you’ve selected Custom from the Configure RAID Drive screen, the
Custom Configuration menu is displayed (Figure 2-19).
