Figure 2–7. A 3-member RAID 0 stripeset (example 1)
The relationship between the chunk size and the average request size determines if striping
maximizes the request rate or the data-transfer rate. You can set the chunk size or use the
default setting (see “Chunk Size,” page 2–23, for information about setting the chunk
size). Figure 2–8 shows another example of a three-member RAID 0 Stripeset.
A major benefit of striping is that it balances the I/O load across all of the disk drives in
the storageset. This can increase the subsystem performance by eliminating the hot spots
(high localities of reference), that occur when frequently accessed data becomes
concentrated on a single disk drive.
