Changing the Volume Allocation Strategy

You can change the allocation strategy for a volume to choose how storage for new
files or additional storage for existing files is allocated on the storage pools that
belong to the volume.

To change the allocation strategy:


In Xsan Admin, select Volumes in the SAN Assets list.


Select the volume in the list and choose Edit Volume Settings from the Action (gear)

pop-up menu.


Choose an allocation strategy from the pop-up menu:

Round Robin: Each request for space is assigned to the next available storage pool in
the volume.
Fill: All data is stored on the first storage pool until it’s full, then on the next storage
pool, and so on.
Balance: New data is written to the storage pool that has the most free space.


Click OK.
