In an asymmetric HA pair setup, the vFiler unit-IPspace configuration in one HA pair is different from that of its partner. For example, each partner might have a different number of vFiler units configured in a specific IPspace, or one partner might have no vFiler units.
A “standby” HA pair is an example of an asymmetric HA pair setup in which one of the hosts is connected to minimal storage of its own. This host takes over its partner’s storage and vFiler units if the partner fails. In such a configuration, the standby host might not have enough storage to support the number of vFiler units that the primary host has.
