5. Once you’ve assembled the disk array groups, click the Logical Drives
tab to continue on to logical drive setup (Figure 4-47):
Figure 4-47. Manual Configuration - Logical Drives
The Logical Drives tab in Manual Configuration is where you configure your
disk arrays into logical drives.
Do the following:
1. Select a RAID level for your first logical drive. Supported RAID levels
are RAID 0, RAID 1, RAID 3, RAID 5, RAID 0+1, and stand-alone
drive (JBOD). Only RAID levels compatible with the current
configuration will be available in the list.
2. Enter the amount of available logical or physical capacity for this
logical drive. If your total configuration will have only one logical
drive which uses all available capacity, the default sizes should not be
changed. If you intend to create additional logical drives now or later,
enter a smaller number to reserve the desired amount of capacity.
3. Check the Write Cache box if you want this logical drive to use Write
Back caching. This improves performance but puts data at risk. You
should have a battery backup unit or uninterruptable power supply if
selecting this feature.
