5.0 VMware and vMotion Support

Beginning with OES 2023, OES supports vMotion for ESX and ESXi servers with version 7.0 or higher.

VMware VMotion enables the live migration of running virtual machines from one physical server to another with zero downtime, continuous service availability, and complete transaction integrity. With a vCenter Server, we can manage multiple ESXi servers and use the vMotion feature to migrate live guests running Open Enterprise Server. During the workload migration, the application is still running and users continue to have access to the systems they need. The migration does not affect the state or operation of the OES Clustering Service, provided that the cluster is configured to use the default standard heartbeat settings.

Ensure that the period of interruption during vMotion does not cause unwanted cluster events. Unwanted cluster events occur if too many heartbeats from the node are missed during the average period of interruption. In that case, relax the heartbeat settings for the time of vMotion.
