Folders with Affinities
To control which storage pools are used to store specific files (for example, to provide
different levels of service for different users or applications), you can associate a folder
on an Xsan volume with an affinity tag that’s assigned to storage pools that make up
the volume.
For example, you can associate some folders with an affinity whose storage pools have
faster LUNs, and associate other folders with an affinity whose storage pools have
safer LUNs. Users can choose between faster and safer storage by putting files in the
appropriate folder.

In the illustration on page 16, the Other folder has an affinity for the faster storage
pool that is based on a RAID 0 array. Any file that a user copies into the Other folder is
stored on the faster array. The Video and Audio folders are associated with the more
secure RAID 5 storage.
