Asymmetrically mirrored HA pairs

You can selectively mirror your storage. For example, you could mirror all the storage on one node, but none of the storage on the other node. Takeover will function normally. However, any unmirrored data is lost if the storage that contains it is damaged or destroyed.

Note: You must connect the unmirrored storage to both nodes, just as for mirrored storage. You cannot have storage that is connected to only one node in an HA pair .
