The following table shows some examples of user templates that might be created:
As for templates, each user template can have a number of adjustable parameters that you can use
for tuning the characteristics of the created volumes.
Note A user template is not directly associated with a storage pool. Its association is implied by its
reference to capabilities and templates.
Application Volume
An application volume is created by ISP, and then exported for use by an application such as a
database or file system. It is identical to a traditional volume that you would create using
vxassist and other VxVM commands, except that you can only administer it by using the
vxvoladm command, or via the interface to ISP that is provided by the VEA. Similarly,
traditional volumes cannot be administered by using the vxvoladm command, or via the VEA
interface to ISP.
Note In this book, the term volume always means application volume unless it is specified that a
traditional VxVM volume is meant.
Intent
The intent of a volume is a conceptualization of its purpose as defined by its characteristics and
implemented by a template. ISP attempts to preserve the intent of a volume whenever the volume is
reconfigured, resized, or relocated. Intent preservation automatically conserves capabilities such as
reliability and performance, and observes additional rules such as allocating storage based on
confinement and exclusion specifications.
