Although this is the simplest way of arranging storage and is expected to be the
most common, it may not provide sufficient flexibility for some installations.
See About arranging storage by attributes on page 31.
About arranging storage by attributes
You can use storage attributes to control how ISP assigns storage to application
volumes. For example, you can use confinement rules to restrict some volumes
to a subset of LUNs which share common attributes, such as caching to enhance
I/O performance, or hardware RAID to provide redundancy and/or enhance
performance.
Not all attributes of LUNs are capable of being discovered automatically. You can
use disk tags, administered using the vxdisk command or the VEA graphical user
interface, to manually attach such attributes to storage.
See About storage pool policies on page 37.
Figure 1-10 shows an example of using attached attributes, where the templates
can use the value of the Building attribute to provide the availability capability
of mirroring volumes between different locations at a site.
