Figure 8–20 Dynamic Logical Drive Expansion
• Mode 1 Expansion (Figure 8–21) involves adding more SCSI hard disk drives to a logical drive,
which may require that the user obtain an enclosure with more drive bays. The data will be re-
striped onto the original and newly added disks.
Figure 8–21 RAID Expansion Mode 1
In Figure 8–21, new drives are added to increase the capacity of a 4-Gigabyte RAID 5 logical drive.
The two new drives increase the capacity to 8 Gigabytes.
• Mode 2 Expansion, on the other hand, requires the same number of higher-capacity SCSI hard
disk drives for a given logical drive.
