Setting the Volume Allocation Strategy
You can set the allocation strategy for a volume to determine the order in which data is
written to the volume’s storage pools.
To set the allocation strategy:
1 In Xsan Admin, select the SAN the volume belongs to, click Setup, and click Storage.
2 Double-click the volume in the list.
3 Choose a value from the Allocation Strategy pop-up menu.
Round Robin: New data is written to the next available storage pool in the volume.
Fill: All data is stored on the first storage pool until it is 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.
4 Click OK, then click Save.
Warning: When you change a volume’s allocation strategy, all data on the volume
and its storage pools is lost.
