Abstract
Techniques to achieve high availability in a multi-controller system are disclosed. In various embodiments, an indication is received that a network ping-based heartbeat mechanism has failed. In response to said indication, an alternative heartbeat is provided at least in part by periodically updating a heartbeat data stored in an on-disk heartbeat data structure, in a portion of a disk that is available to both an active controller and a standby controller of the multi-controller system.
