Configuring Units
Table 2: Possible Configurations Based on Number of Drives
# Drives | Possible Configurations |
|
2RAID 0 or RAID 1
3RAID 0
RAID 1 with hot spare RAID 5
4RAID 5 + hot spare RAID 10
Combination of RAID 0, RAID 1, single disks
5RAID 5 + hot spare RAID 10 + hot spare
Combination of RAID 0, RAID 1, hot spare, or single disks
6 or more RAID 50
Depending on the number of drives, a RAID 50 may contain from 2 to 4 subunits. For example, with 12 drives, possible RAID 50 configurations include 2 subunits of 6, 3 subunits of 4, or 4 subunits of 3. With 10 drives, a RAID 50 will contain 2 subunits of 5 drives each.
Combination of RAID 0, 1, 5, 10, hot spare, or single disks
Drive Capacity Considerations
The capacity of each drive is limited to the capacity of the smallest drive in the array. The total array capacity is defined as follows:
Table 3: Drive Capacity
RAID Level | Capacity |
|
|
RAID 0 | (number of drives) X (capacity of the smallest drive) |
|
|
RAID 1 | capacity of the smallest drive |
