Chapter 4
Although each drive in an array must have the same capacity, one
logical drive can span two or more arrays with different capacities. For
example, one array might contain three drives of 4 MB each, and the
second array might contain three drives of 12 MB each. One logical
drive can span both of these arrays.
Spanned arrays must be numbered consecutively.
When you use an HP NetRAID utility to configure your system, and
you specify that a logical drive will span arrays, the system will span
all eligible arrays that are numbered consecutively and that contain
the same number of disk drives, up to a maximum of four arrays.
