Abstract: One or more techniques and/or computing devices are provided for determining whether to perform a switchover operation between computing nodes. A first computing node and a second computing node, configured as disaster recovery partners, may be deployed within a computing environment. The first computing node and the second computing node may be configured to provide operational state information (e.g., normal operation, a failure, etc.) to a cloud environment node state provider and/or cloud persistent storage accessible through a cloud storage service. Accordingly, a computing node may obtain operational state information of a partner node from the cloud environment node state provider and/or the cloud storage service notwithstanding a loss of internode communication and/or an infrastructure failure that may otherwise appear as a failure of the partner node. In this way, the computing node may accurately determine whether the partner node has failed.

Abstract: Techniques are provided for metadata management for enabling automated switchover in accordance with a configuration of storage solution that expresses a preference for either maintaining availability (e.g., a non-zero RPO mode) of the storage solution or avoiding data loss (e.g., a zero RPO mode). In one example, responsive to detecting a switchover trigger event, a node of a local cluster of a cross-site storage solution determines whether performance of an automated switchover from a failed cluster to a surviving cluster of the cross-site storage solution is enabled. Responsive to an affirmative determination, the node selectively proceeds with the automated switchover based on the configuration.
