Creating a RAID Volume Based on Multiple Drive Groups: RAID 00, 10, 50, and 60

Disk spanning allows multiple drive groups to function like one big drive. Spanning overcomes a lack of disk space
and simplifies storage management by combining existing resources or adding relatively inexpensive resources.
Spanning alone does not provide reliability or performance enhancements. Spanned virtual drives must have the
same stripe size and must be contiguous. With spanning, a RAID 1 drive group is turned into a RAID 10 drive
group (Figure 10).
Figure 10. RAID 10
Spanning two contiguous RAID 0 virtual drives does not produce a new RAID level or add fault tolerance. It does
increase the capacity of the virtual drive and improves performance by doubling the number of physical disks.
Table 9 describes how to configure RAID 00, 10, 50, and 60. The virtual drives must have the same stripe size,
and the maximum number of spans is eight. The full drive capacity is used when you span virtual drives.
