1. Go to "Storage Manager" > "STORAGE" > "Storage Space".

2. Double click a storage pool to set a threshold to bring up the Storage Pool

Management page.

3. Click "Actions" > "Set Threshold".

Setting Snapshot Reservation

You can set snapshot reservation space to ensure enough space for saving snapshots.

Snapshot reservation is set as a percentage of total storage pool space and there are

two scenarios:

When the snapshot reserve is set to 0%, new snapshots taken will all be saved to a

storage pool until that storage pool runs out of its space. When that happens, the

system will start recycling older snapshots regardless the snapshot limitation set in

Snapshot Global Settings .
