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)
Choose an allocation strategy from the pop-up menu:
Round Robin: Each request for space is assigned to the next available storage pool in
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.
