perform manually. ISP aids you in managing large sets of storage by providing
an allocation engine that chooses which storage to use based on the capabilities
that you specify for the volumes to be created.
The main differences between the traditional model for creating volumes and ISP
are that the set of information about the available storage is potentially unlimited,
and the set of rules that the allocation engine uses to choose storage is defined
externally to commands such as vxassist and vxvoladm.
Figure 1-2 illustrates how ISP improves on the traditional model for creating
volumes.

You can define additional
attributes that are to be
used when selecting
storage.
Application volumes with the required
capabilities are built within the storage
pool according to pre-defined and
user-specified rules and templates.
The vxassist or vxvoladm commands use the
allocation engine to select available storage
from the storage pool when creating and
administering application volumes.
