Figure 2-12 shows how a striped volume is allocated, assuming that 10 extents are 
required.

A sequential volume is where the extents are allocated one after the other, from one 
MDisk to the next MDisk (see Figure 2-13).

Image mode volumes are special volumes that have a direct relationship with one MDisk. 
They are used to migrate data into and out of the clustered system.
