during their life cycle. File relocation may be triggered according to various criteria
such as frequency of access, ownership and size changes.
To set up a storage tier begin by tagging those volumes that you want to place in
a tiered hierarchy, add these volumes to a volume set, and then implement the
policies your enterprise has decided to use. For example, a policy might say that
customer transaction records should be moved from the top tier (for example,
gold) to a middle tier (silver) when they have not been accessed for 30 days, and
from the middle tier to the lowest tier when they have not been accessed for 120
days.
Figure 3-1 illustrates such a configuration where a file system has been created
on a volume set that is composed of volumes that have been tagged with tier values
that correspond to the cost of the storage from which they have been created.
