A.3. Affinities
Storage pools can be assigned an affinity. When data is moved to the affinity, space is allocated from a specific storage pool rather than in a round-robin fashion across all the storage pools. Affinity data can be restricted to specific LUNs. Access to affinities can be limited to certain groups. Data that requires a higher level of integrity can then be given an affinity or volatile data that requires speed (such as a capture scratch) can be given the fastest possible storage (ie – SAS drives running on a RAID 0-based LUN).
You can use Xsan Admin to assign an affinity to a folder at the top level of a volume. However, to assign an affinity to a nested folder, use the cvmkdir command. For example:
sudo /Library/Filesystems/Xsan/bin/cvmkdir ...
